摘要

形状记忆聚合物(SMPs)是一种刺激响应型智能材料，在受到热、电、交变磁场、光、湿度或化学等外界刺激时，材料能够发生较大的可回复形变，在生物医用材料、航天航空、汽车、纺织等领域有广泛的应用。但SMPs强度和模量低，形状回复应力小，回复速度较慢等缺点限制了其应用，纳米复合可以克服SMPs的这些缺点。本文在介绍SMPS的基础理论基础上，从纳米改性的目的和激发方式出发，综述了不同纳米颗粒与SMPs的作用机理，并展望了纳米复合SMPs的研究和发展趋势。

Abstract

Shape memory polymers (SMPs) are a class of stimuli responsive materials

which may recover their original shapes from large deformation upon the application of an external stimulus such as heat

electricity

alternating magnetic fields

light

water or chemicals

et al. They have been widely used in the fields of biomedical materials

aerospace

automobiles

textiles as smart materials. However

their development and applications are partly restricted by their low mechanical properties

such as low strength

elastic modulus

recovery forces and slow recovery rates. Incorporation of nanoparticles would contribute to the improvement of mechanical and shape memory properties of SMPs. Based on a fundamental understanding of the shape memory mechanism of SMPs

this paper aims to provide a review of shape memory polymer nanocomposites

including the purpose of the incorporation of nanoparticles

stimulus methods and mechanism

the interaction mechanism between nanoparticles and polymer matrix and their potential applications. Finally

the research trends of SMP nanocomposites are also summarized.
