摘要:
制备了具有形状记忆效应的天然橡胶(NR)/反式-1,4-聚异戊二烯(TPI)复合材料,研究了碳纳米管填料用量对复合材料性能的影响。结果表明,随着碳纳米管用量的增加,复合材料的焦烧时间和工艺正硫化时间均缩短,硫化速率和交联密度略有提高;拉伸强度、定伸应力和硬度均呈现明显的上升趋势,而扯断伸长率无明显变化,证明碳纳米管起到了增强的作用;然而,形状记忆性能中的形状固定率从91.83%下降到86.64%,形状回复率从95.43%下降到90.76%。在CNTs用量为6份(质量)、直流电压在80 V以上时,复合材料展现出良好的电刺激形状记忆行为。
Abstract:
Natural rubber (NR)/trans-1,4-polyisoprene (TPI) composites with shape memory effect were prepared, and the effect of carbon nanotubes (CNTs) amount on the properties of the composites was studied. The results showed that with the increase of CNTS, the scorch time and curing time of the composites were shortened, and the curing rate and crosslinking density were slightly increased, and the tensile strength, modulus and hardness all showed an obvious upward trend, while the elongation at break did not change significantly, indicating that CNTs played a reinforcing role. However, the shape fixation rate decreased from 91.83% to 86.64%, and the shape recovery rate dropped from 95.43% to 90.76% in the shape memory properties. When the amount of CNTs was 6 phr(mass) and the DC voltage was above 80 V, the composites exhibited good electrical stimulation shape memory behavior.
