摘要:

界面聚合通常指限定在液-液或液-固界面上进行的聚合反应,散见于少数高活性的缩聚反应体系。20世纪90年代,以RAFT聚合、ATRP等为代表的可逆失活自由基聚合(reversible deactivation radical polymerization,RDRP)因其兼具传统自由基聚合和活性阴离子聚合的优点,广泛用于聚合物链结构的可控制备。另一方面,RDRP已被用于构建更为普适的界面聚合反应,基于RDRP的界面聚合已发展成为一种可控制备具有精准纳米结构的功能性聚合物产品的新方法。本文以RAFT液-液界面聚合为主,阐述了RAFT法和ATRP法在液-液界面、液-固界面进行“活性”聚合的反应机理,总结了该领域的研究进展。在此基础上,重点介绍“活性”界面聚合在构建纳米(中空)胶囊、纳米界面工程与纳米分散以及纳米聚合物刷表面等方面的潜在应用前景。

Abstract:

Interfacial polymerization generally refers to polymerization confined to liquid-liquid or liquid-solid interfaces. Interfacial polymerization had occurred in some specific cases of highly reactive condensation polymerization. Since 1990s, reversible deactivation radical polymerizations (RDRPs) represented by RAFT polymerization and ATRP have been developed into powerful tools to precisely tailor-make microstructures of polymer chains. Besides polymer chains, precise nanostructures have been synthesized robustly from RDRP-based interfacial polymerization. In the current mini-review, we introduce how to create a RDRP-based interfacial polymerization, summarize the up-to-date status of the available nanostructures and promising application fields in nanocapsules, nano-dispersion and polymer brush surface from interfacial RDRPs.

Key words: interface, polymerization, nanostructure, nanocapsules, interfacial engineering, polymer brush
