This brief perspective overviews amphiphilic polymer co‐networks (APCNs), polymeric chemically crosslinked hydrogels also covalently hosting a hydrophobic segment, conferring upon these materials the important property of internal self‐organization in aqueous environments. APCN synthesis is most conveniently accomplished via the random crosslinking copolymerization of a hydrophilic monomer with a hydrophobic macro‐crosslinker, whereas better structures are attained via the end‐linking of amphiphilic linear ABA triblock copolymers or amphiphilic star diblock copolymers. Microphase‐separated morphologies, translucency‐to‐transparency, biocompatibility, low to moderate aqueous swelling, fair mechanical strength and possible stimulus‐responsiveness constitute the main physicochemical properties of APCNs, with their major commercial application being in silicone hydrogel soft contact lenses. Modeling the swelling, morphological and mechanical behavior of these intriguing materials is an area where more progress is necessary in order to improve our understanding of these networks and facilitate the design of next‐generation APCNs. © 2020 Society of Industrial Chemistry

两亲性聚合物共网络:32岁,并且变得越来越强–一个观点

该简要概述概述了两亲性聚合物共网络(APCN),聚合化学交联的水凝胶也共价包含疏水链段,从而赋予这些材料在水性环境中内部自组织的重要特性。通过亲水性单体与疏水性大分子交联剂的无规交联共聚,可以最方便地完成APCN的合成,而通过两亲性线性ABA三嵌段共聚物或两亲星形二嵌段共聚物的末端键合,可以获得更好的结构。微相分离的形态,半透明性,生物相容性,中低水溶胀,中等机械强度和可能的刺激响应性是APCN的主要理化性质,它们的主要商业应用是硅水凝胶软性隐形眼镜。对这些引人入胜的材料的溶胀,形态和力学行为进行建模是一个需要进一步发展的领域,以便增进我们对这些网络的理解并促进下一代APCN的设计。©2020工业化学学会
