摘要

采用动态硫化的方法制备了多重结晶反式聚异戊二烯(TPI)/聚丁烯-1 (PB-1)形状记忆材料，研究不同份数的PB-1与TPI共混的聚集态结构和交联结构对形状记忆性能的调控作用。结果表明，当30份PB-1与TPI共混时，PB-1形成连续相区，使共混体系的第一临时形状固定率

f (O→A)

和第二临时形状固定率

f (A→B)

分别提升至86.2%和95.4%。利用共混体系分子链交联网络与结晶结构协同作用，实现多温度点触发，为材料提供了多重形状记忆能力与耐热能力，为开发耐热型柔性智能器件、温度传感器等材料提供了可能性。

Abstract

Multi-crystalline

trans

-polyisoprene (TPI)/polybutene-1 (PB-1) shape memory materials were prepared

via

dynamic vulcanization. The influence of blending varying amounts of PB-1 with TPI on the condensed matter structure

crosslinked network

and resulting shape memory properties was investigated. The results indicate that when 30 phr of PB-1 was blended with TPI

PB-1 formed a continuous phase regio

which increased the first temporary shape fixity ratio

f (O→A)

and the second temporary shape fixity ratio

f (A→B)

of the blended system to 86.2% and 95.4%

respectively. Leveraging the synergistic effect between the molecular chain crosslinked network and the crystalline structure of the blended system enables triggering at multiple temperature points. This endows the material with multi-shape memory capability and enhanced thermal resistance

offering potential for application in heat-resistant flexible intelligent devices and temperature sensors.
