摘要

提出了一种以超高分子量聚乙烯为基材,利用聚合物的裂纹策略制备硬弹性高分子材料的新方法。该方法包括超高分子量聚乙烯原始薄膜通过环境晶间擦伤机制的变形过程以及随后的应力松弛低温自发应变恢复过程。结果表明,该材料获得了典型的硬弹性材料的新性能:在空气中二次变形高达~20 vol %后,恢复了孔径在纳米级(小于10 nm)的多孔结构,变形的可逆性高(50-85%),并且在循环加载下具有开闭孔的效果。提出了这种现象的机理,并指出了这种机械敏感材料的实际应用领域。

Preparation of a New Hard-Elastic Polymeric Material Based on Ultra-High-Molecular-Weight Polyethylene

Preparation of a New Hard-Elastic Polymeric Material Based on Ultra-High-Molecular-Weight Polyethylene

A novel approach to the preparation of a hard-elastic polymeric material based on ultra-high-molecular-weight polyethylene using the strategy of crazing of polymers was proposed. This approach comprises the process of deformation of the pristine films of ultra-high-molecular-weight polyethylene via the environmental intercrystallite crazing mechanism and the subsequent low-temperature spontaneous strain recovery upon stress relaxation. As a result, the material acquires new properties typical of hard-elastic materials: restoration of the porous structure with pore sizes in the nanometer range (less than 10 nm) after the secondary deformation in air up to ~20 vol %, high reversibility of deformation (50–85%), and the effect of opening and closing of pores under cyclic loading. The mechanism of this phenomenon was proposed, and the fields of practical applications of this kind of mechanosensitive material were indicated.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
