橡胶基质对橡胶/细菌纤维素晶须复合材料的水刺激-力响应性能的影响

分别选用丁苯橡胶(SBR)、天然橡胶和羧基丁腈橡胶作为基质,采用蒸发法将细菌纤维素晶须(BCWs)分别与3种橡胶胶乳混合,制备了橡胶/细菌纤维素晶须复合材料,研究了橡胶基质对复合材料吸水性能及水刺激-力响应性能的影响。结果表明,加入BCWs后,3种橡胶基质制备复合材料的吸水性能都得到增强,常温储能模量均明显下降,幅度可达到2个数量级。3种基质中以非极性橡胶SBR制备的SBR/BCWs的吸水性能和水刺激-力响应性能为最佳。...

Summary:分别选用丁苯橡胶(SBR)、天然橡胶和羧基丁腈橡胶作为基质,采用蒸发法将细菌纤维素晶须(BCWs)分别与3种橡胶胶乳混合,制备了橡胶/细菌纤维素晶须复合材料,研究了橡胶基质对复合材料吸水性能及水刺激-力响应性能的影响。结果表明,加入BCWs后,3种橡胶基质制备复合材料的吸水性能都得到增强,常温储能模量均明显下降,幅度可达到2个数量级。3种基质中以非极性橡胶SBR制备的SBR/BCWs的吸水性能和水刺激-力响应性能为最佳。
Bibliography:Bacterial cellulose whiskers (BCWs) arc crystalline rod-like nano- fillers obtained from bacterial cellulose via acid hydrolysis. They are ideal nanoreinforcements owning to their renewable nature, low cost, high aspect ratio, high crystallinity, etc. In this study, stimuli-re- sponsive nanocomposites based on three kinds of matrixes, i.e. sty- rene-butadiene rubber (SBR) , natural rubber (NR) , carboxylated acrylonitrile-butadiene rubber (XNBR) , and 10 phr BCWs were pre- pared by evaporation method respectivelly.
