Abstract:

A highly aligned carbon nanotube sheet orients crosslinked liquid-crystalline polymer through a simple melting process (see picture). The resulting composite film can be rapidly bent and unbent by alternate irradiation with UV and visible light. The film also exhibits excellent mechanical and electrical properties due to the incorporation of aligned CNTs.

该研究报道了一种在简单的熔融过程中，利用高度排列的碳纳米管诱导液晶基元取向，进而制备可形变CLCP复合膜的新方法。在紫外光和可见光的交替照射下，CLCP复合膜具有快速和可逆的光致形变。与传统机械摩擦法制备的CLCPs相比，CLCP/CNT复合膜的机械强度明显提高，且具有较高的导电性。CLCP/CNT复合薄膜具有良好的综合性能，其可广泛应用于驱动执行器和微型机器人的新型高性能驱动材料。
