摘要
聚N-异丙基丙烯酰胺(PNIPAM)类智能凝胶与纳米金(AuNPs)组成的复合材料兼具了金的光学性质和PNIPAM的温敏特性,受到国内外专家学者的普遍关注。本文介绍了该复合物的制备方法,主要包括直接分散法、聚合物基底原位合成法、AuNPs原位合成法、模板法等,并对各自特点进行了说明。此外,文中还对PNIPAM类智能凝胶与AuNPs组成的复合材料的各种应用进行了综述,简要分析了目前存在的问题并展望了今后该材料的研究方向。
The composites which are made of intelligent hydrogels,poly(N-isopropyl acrylamide)(PNIPAM),and Au nanoparticles(AuNPs) have drawn great attentions because they have thermo-responsive behavior of PNIPAM with optical properties of AuNPs.Here,the preparation methods of the composites and their traits are reviewed,which include direct dispersion,in-situ polymerization,in-situ synthesis of nanoparticles,template methods,etc.Furthermore,the applications of these composites are introduced in aspects of photothermally modulated drug delivery,surface-enhanced Raman scattering,catalysis,on-off valve,sensing and supramolecular self-assembly.Finally,current problems and prospects of the future researches on the composites are proposed.
