Biomimetic water-responsive shape memory composite material and preparation method thereof

Abstract

The invention relates to the technical field of biomimetic materials, and concretely provides a biomimetic water-responsive shape memory composite material. The biomimetic water-responsive shape memory composite material is prepared by mixing polyvinyl alcohol with a polymer having a beta-folded structure. The composite material obtained in the invention has the water-responsive shape memory characteristic, and has a shape memory fixing rate of 95% or more and a recovery rate of 95% or more. 本发明涉及仿生材料技术领域，具体提供一种仿生水响应形状记忆复合材料。所述仿生水响应形状记忆复合材料为由聚乙烯醇和具有β‑折叠结构的聚合物混合而成。本发明获得的复合材料具有水响应形状记忆特性，其形状记忆固定率达95％及以上和回复率达到95％及以上。
