Control on the Filler-Matrix Interfacial Interaction and Its Influence on Rubber Reinforcement of HAF/NR CompositesHAN Jing-jie, HE Xue-lian, LI Qiu-ying, GUO Wei-hong, WU Chi-fei Polymer Alloy Laboratory, School of Materials Science and Engineering, East China University of Science and Technology, Shanghai 200237, ChinaAbstract:The method of in situ grafting special molecular whose side chains had pyridine functions onto high abrasion resistance furnace black particles （HAF） was used to control the filler-matrix interracial interaction. The Ayala parameter was adopted as a function to determine quantitatively the level of the filler-matrix interracial interaction. Influence of the interracial interaction on natural rubber （NR） rein- forcement was studied. From the stress strain behavior of the HAF/NR composites, it could be concluded that the grafted furnace black （GCB） showed improved mechanical properties. The reason was that GCB improved the filler-matrix interaction, weakened the filler-filler interaction and the result was in full agreement with the fit results of Guth-Gold equation.[著者文摘]
