聚合诱导自组装(PISA)技术的应用研究进展

Application of Polymerization-induced Self-assembly(PISA)Technology

聚合诱导自组装(PISA)技术是制备嵌段共聚物纳米自组装体的一种新技术.相较于传统的嵌段共聚物自组装技术,该技术具有边聚合、边组装的操作简便性特点,同时还具有纳米自组装体形态可控、固含量高(高达50%)等优点,使得聚合物纳米自组装体的规模化生产和应用成为可能.经过十多年的发展,基于各种“活性”/可控聚合机理和各种配方组合的PISA体系已经被成功实现,PISA技术在各个领域的应用研究也得到了全面的推进.目前关于PISA中的组装体形态研究已经有不少综述,而针对PISA技术应用方面的综述却鲜有报道.因此,本文在简要介绍PISA技术的基本原理和发展现状的基础上,重点总结了PISA技术在纳米复合材料、生物医用材料、电池、功能涂料、Pickering乳化剂、纳米结构膜、水凝胶、发光材料等相关领域的研究动态和应用进展.希望本综述能为PISA领域的研究者提供借鉴,并进一步促进聚合物自组装相关领域的研究进展.

The polymerization-induced self-assembly(PISA)has been developed as a versatile technique to prepare the block copolymer-based nano-objects.Compared with the traditional block copolymer-based self-assembly technology,the PISA technology is featured with a polymerization process and a simultaneous self-assembly process,as well as with well-controlled morphologies and high solid content(up to 50 wt%).These advantages have facilitated the large-scale production and application of the nano-objects.Based on the modification of various“living”/controlled polymerization mechanisms and the optimization of various formulations,the PISA technology has been well developed over the past decade.Correspondingly,the application of the PISA technology is also widely used.Up to now,several reviews on the morphology evolution of PISA technology have been presented.However,a comprehensive summary on the application of PISA technique is still needed.In this review,following with a brief introduction on the fundamental principle and the status of PISA technology,the application of PISA in nanocomposite materials,biomedical materials,batteries,functional coatings,Pickering emulsifiers,nanostructured membranes,hydrogels,luminescent materials,and other fields will be focused and summarized.This summary is hoped to depict a comprehensive outline of PISA technology in recent years and to prompt the development of the self-assembly technology in interdisciplinary field.
