Abstract
Nanocavitation was detected for the first time in carbon black filled styrene-butadiene rubber (CB-SBR) under uniaxial loading by real time small-angle X-ray scattering (SAXS) using synchrotron X-ray radiation. A three phase model was developed to calculate the void volume fraction from the scattering invariant Q determined from the observed SAXS patterns. The normalized scattering invariant Q/Q0, where Q0 is the invariant before deformation, greatly increased above a critical extension ratio λonset which we attribute to the formation of nanovoids. Analysis of the 2D scattering patterns show that voids formed are 20-40 nm in size and elongated along the tensile direction. Cavities formed beyond λonset are smaller as λ increases. Results from the scattering experiments are strongly supported by macroscopic volume change measurements on the samples under similar uniaxial strain. A nearly constant nanocavitation stress σonset (25 MPa) was observed when the filler volume fraction φCB was larger than 14%. This value is much higher than that predicted based on the elastic instability of small voids in an unfilled elastomer and shows only a weak dependence on the cross-linking density νC in heavily cross-linked samples. An energy based cavitation criterion stressing the importance of confined domains between particles or clusters of particles was adopted and found to be consistent with the observed results. The nanocavities are thought to alter the local stress state and promote local shear motion of filler particles.

This value is much higher than that predicted based on the elastic instability of small voids in an unfilled elastomer and shows only a weak dependence on the cross-linking density ν<sub>C</sub> in heavily cross-linked samples. An energy based cavitation criterion stressing the importance of confined domains between particles or clusters of particles was adopted and found to be consistent with the observed results. The nanocavities are thought to alter the local stress state and promote local shear motion of filler particles.</s0></fC01><fC02 i1="01" i2="X"><s0>001D09D04B</s0></fC02><fC03 i1="01" i2="X" l="FRE"><s0>Vulcanisat</s0><s5>01</s5></fC03><fC03 i1="01" i2="X" l="ENG"><s0>Vulcanizate</s0><s5>01</s5></fC03><fC03 i1="01" i2="X" l="SPA"><s0>Vulcanizado</s0><s5>01</s5></fC03><fC03 i1="02" i2="X" l="FRE"><s0>SBR</s0><s5>02</s5></fC03><fC03 i1="02" i2="X" l="ENG"><s0>SBR</s0><s5>02</s5></fC03><fC03 i1="02" i2="X" l="SPA"><s0>SBR</s0><s5>02</s5></fC03><fC03 i1="03" i2="3" l="FRE"><s0>Polymère chargé</s0><s5>03</s5></fC03><fC03 i1="03" i2="3" l="ENG"><s0>Filled polymers</s0><s5>03</s5></fC03><fC03 i1="04" i2="X" l="FRE"><s0>Noir carbone</s0><s1>SEC</s1><s5>04</s5></fC03><fC03 i1="04" i2="X" l="ENG"><s0>Carbon black</s0><s1>SEC</s1><s5>04</s5></fC03><fC03 i1="04" i2="X" l="SPA"><s0>Carbón negro</s0><s1>SEC</s1><s5>04</s5></fC03><fC03 i1="05" i2="X" l="FRE"><s0>Effet concentration</s0><s5>05</s5></fC03><fC03 i1="05" i2="X" l="ENG"><s0>Concentration effect</s0><s5>05</s5></fC03><fC03 i1="05" i2="X" l="SPA"><s0>Efecto concentración</s0><s5>05</s5></fC03><fC03 i1="06" i2="X" l="FRE"><s0>Allongement mécanique</s0><s5>07</s5></fC03><fC03 i1="06" i2="X" l="ENG"><s0>Elongation (mechanics)</s0><s5>07</s5></fC03><fC03 i1="06" i2="X" l="SPA"><s0>Alargamiento (mecánico)</s0><s5>07</s5></fC03><fC03 i1="07" i2="X" l="FRE"><s0>Cavitation</s0><s5>09</s5></fC03><fC03 i1="07" i2="X" l="ENG"><s0>Cavitation</s0><s5>09</s5></fC03><fC03 i1="07" i2="X" l="SPA"><s0>Cavitación</s0><s5>09</s5></fC03><fC03 i1="08" i2="X" l="FRE"><s0>Fraction vide</s0><s5>10</s5></fC03><fC03 i1="08" i2="X" l="ENG"><s0>Void fraction</s0><s5>10</s5></fC03><fC03 i1="08" i2="X" l="SPA"><s0>Fracción vacío</s0><s5>10</s5></fC03><fC03 i1="09" i2="X" l="FRE"><s0>Méthode étude</s0><s5>13</s5></fC03><fC03 i1="09" i2="X" l="ENG"><s0>Investigation method</s0><s5>13</s5></fC03><fC03 i1="09" i2="X" l="SPA"><s0>Método estudio</s0><s5>13</s5></fC03><fC03 i1="10" i2="X" l="FRE"><s0>Diffusion RX centrale</s0><s5>14</s5></fC03><fC03 i1="10" i2="X" l="ENG"><s0>Small angle X ray scattering</s0><s5>14</s5></fC03><fC03 i1="10" i2="X" l="SPA"><s0>Difusión rayo X central</s0><s5>14</s5></fC03><fC03 i1="11" i2="X" l="FRE"><s0>Temps réel</s0><s5>15</s5></fC03><fC03 i1="11" i2="X" l="ENG"><s0>Real time</s0><s5>15</s5></fC03><fC03 i1="11" i2="X" l="SPA"><s0>Tiempo real</s0><s5>15</s5></fC03><fC03 i1="12" i2="X" l="FRE"><s0>Etude expérimentale</s0><s5>17</s5></fC03><fC03 i1="12" i2="X" l="ENG"><s0>Experimental study</s0><s5>17</s5></fC03><fC03 i1="12" i2="X" l="SPA"><s0>Estudio experimental</s0><s5>17</s5></fC03><fC03 i1="13" i2="X" l="FRE"><s0>Nanocavitation</s0><s4>INC</s4><s5>32</s5></fC03><fC03 i1="14" i2="X" l="FRE"><s0>Modèle 3 phases</s0><s4>INC</s4><s5>33</s5></fC03><fC07 i1="01" i2="X" l="FRE"><s0>Déformation uniaxiale</s0><s5>06</s5></fC07><fC07 i1="01" i2="X" l="ENG"><s0>Uniaxial strain</s0><s5>06</s5></fC07><fC07 i1="01" i2="X" l="SPA"><s0>Deformación uniaxial</s0><s5>06</s5></fC07><fN21><s1>156</s1></fN21><fN44 i1="01"><s1>PSI</s1></fN44><fN82><s1>PSI</s1></fN82></pA></standard><server><NO>PASCAL 12-0204575 INIST</NO><ET>Nanocavitation in Carbon Black Filled Styrene-Butadiene Rubber under Tension Detected by Real Time Small Angle X-ray Scattering</ET><AU>HUAN ZHANG; SCHOLZ (Arthur K.); DE CREVOISIER (Jordan); VION-LOISEL (Fabien); BESNARD (Gilles); HEXEMER (Alexander); BROWN (Hugh R.); KRAMER (Edward J.); CRETIN (Costantino)</AU><AF>Laboratory of Soft Matter Science and Engineering, ESPCI Paristech-CNRS-UPMC, 10 rue Vauquelin/75005 Paris/France (1 aut., 3 aut., 9 aut.); Materials Research Laboratory, University of California/Santa Barbara, California 93106/Etats-Unis (2 aut., 8 aut.); Department of Materials, University of California/Santa Barbara, California 93106/Etats-Unis (2 aut., 8 aut.); Department of Chemical Engineering, University of California/Santa Barbara, California 93106/Etats-Unis (8 aut.); Michelin, CERL Ladoux/63040 Clermont Ferrand/France (4 aut.); University of Wollongong/Wollongong/Australie (7 aut.); LMT-Cachan, ENS-Cachan, 61 avenue du président Wilson/94230 Cachan/France (3 aut., 5 aut.); Advanced Light Source, Lawrence Berkeley National Laboratory, 1 Cyclotron Road/Berkeley, California 94720/Etats-Unis (6 aut.)</AF><DT>Publication en série; Niveau analytique</DT><SO>Macromolecules : (Print); ISSN 0024-9297; Coden MAMOBX; Etats-Unis; Da. 2012; Vol. 45; No. 3; Pp. 1529-1543; Bibl. 73 ref.</SO><LA>Anglais</LA><EA>Nanocavitation was detected for the first time in carbon black filled styrene-butadiene rubber (CB-SBR) under uniaxial loading by real time small-angle X-ray scattering (SAXS) using synchrotron X-ray radiation. A three phase model was developed to calculate the void volume fraction from the scattering invariant Q determined from the observed SAXS patterns. The normalized scattering invariant Q/Q<sub>0</sub>, where Q<sub>0</sub> is the invariant before deformation, greatly increased above a critical extension ratio λ<sub>onset</sub> which we attribute to the formation of nanovoids. Analysis of the 2D scattering patterns show that voids formed are 20-40 nm in size and elongated along the tensile direction. Cavities formed beyond λ<sub>onset</sub> are smaller as λ increases. Results from the scattering experiments are strongly supported by macroscopic volume change measurements on the samples under similar uniaxial strain. A nearly constant nanocavitation stress σ<sub>onset</sub> (25 MPa) was observed when the filler volume fraction φ<sub>CB</sub> was larger than 14%. This value is much higher than that predicted based on the elastic instability of small voids in an unfilled elastomer and shows only a weak dependence on the cross-linking density ν<sub>C</sub> in heavily cross-linked samples. An energy based cavitation criterion stressing the importance of confined domains between particles or clusters of particles was adopted and found to be consistent with the observed results. The nanocavities are thought to alter the local stress state and promote local shear motion of filler particles.</EA><CC>001D09D04B</CC><FD>Vulcanisat; SBR; Polymère chargé; Noir carbone; Effet concentration; Allongement mécanique; Cavitation; Fraction vide; Méthode étude; Diffusion RX centrale; Temps réel; Etude expérimentale; Nanocavitation; Modèle 3 phases</FD><FG>Déformation uniaxiale</FG><ED>Vulcanizate; SBR; Filled polymers; Carbon black; Concentration effect; Elongation (mechanics); Cavitation; Void fraction; Investigation method; Small angle X ray scattering; Real time; Experimental study</ED><EG>Uniaxial strain</EG><SD>Vulcanizado; SBR; Carbón negro; Efecto concentración; Alargamiento (mecánico); Cavitación; Fracción vacío; Método estudio; Difusión rayo X central; Tiempo real; Estudio experimental</SD><LO>INIST-13789.354000509220620450</LO><ID>12-0204575</ID></server></inist></record>Pour manipuler ce document sous Unix (Dilib)
