摘要

超高分子量聚乙烯(Ultra-high molecular weight polyethylene， UHMWPE)因其特有的简单规整长线性结构，分子链易于紧密堆砌与缠结。这虽然使其不能通过一般热塑性塑料加工方法成型，但也为材料结构设计和功能化带来契机。大量研究表明，利用UHMWPE分子量的多分散性、软硬相与物理交联密度的可调节性、拉伸条件下的致孔和诱导结晶效应，以及易于实现结晶相分离等特点，均可进行功能化及复合材料设计。本文综述了近年来UHMWPE功能复合材料研发及其应用进展，展望了其在电磁屏蔽、智能响应、生物医用、热管理等领域的独特优势和广阔发展前景。

Abstract

Ultra-high molecular weight polyethylene (UHMWPE) chains are prone to be closely packed and tangle because of the simple and regular long linear structure. Although the resultant bottlenecks in processing of high- performance UHMWPE materials restrict their large-scale development and applications

the unique structure indicate various opportunities for functionalization and materials design. Based on the excellent properties of UHMWPE

a considerable number of studies have shown that functionalization and composites design can be achieved by taking advantages of the polydispersity of molecular weight

adjustable soft/hard phase and physical cross-linking density

pore- foaming effects and stress-induced crystallization under stretching

crystallization-induced phase separation and other characteristics. In this mini-review

the development and application of UHMWPE-based functional composites in recent years are summarized to illustrate the unique advantages and broad prospects of UHMWPE in electromagnetic shielding

intelligent response

biomedicine and thermal management.
