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。
(SBR), natural rubber and carboxylated nitrile rubber (SBR) were selected as the matrix. The bacterial cellulose whiskers (BCWs) were respectively mixed with three kinds of rubber latex by evaporation to prepare the rubber / bacterial cellulose whisker composite , The effect of rubber matrix on the water absorption and water-stimulation-force response of the composites was studied. The results show that after adding BCWs, the water absorption properties of the three rubber matrix composites are enhanced, storage modulus at room temperature decreased significantly, up to 2 orders of magnitude. The SBR / BCWs prepared from non-polar SBRs in three kinds of matrices had the best water absorption and water-stimulation-force response properties.
