摘要:

以壳聚糖作为填料、脱蛋白环氧化天然橡胶（ENR）作为基质材料，制备了生物基形状记忆复合材料，通过傅里叶变换红外光谱、原子力显微镜、电子万能试验机等研究了该形状记忆复合材料的微观结构、力学性能及形状记忆性能。结果表明，加入壳聚糖后ENR的有序结晶相以更小、更均匀的尺寸分散在整个体系中；由于壳聚糖的增强增韧作用，该形状记忆复合材料的耐磨性能增强、力学性能逐渐提高。此外，壳聚糖的加入进一步提高了ENR的形状记忆性能。

Abstract:

A bio-based shape memory composite was prepared with chitosan as filler and deproteinized epoxidized natural rubber （ENR) as matrix, and the microstructure, mechanical properties, and shape memory performance of the shape memory composite materials were investigated by Fourier transform infrared spectroscopy, atomic force microscope, electronic universal testing machine, etc. The results showed that the addition of chitosan dispersed the ordered crystalline phases of ENR into smaller and more uniformly sized particles throughout the system. Due to the strengthening and toughening effect of chitosan, the abrasion resistance of the shape memory composite material was enhanced and its mechanical properties improved gradually. Furthermore, the addition of chitosan further improved the shape memory performance of ENR.
