聚电解质是广泛应用于医疗领域的一类高分子聚合物,该文从多方面对聚电解质润滑涂层进行了系统的概述。首先,基于聚电解质刷原理、水合润滑原理对聚电解质润滑涂层的润滑机理展开介绍,并对聚电解质进行了分类。其次,介绍了聚电解质与基底的多种结合方式,包括物理法、偶联接枝法和引发接枝法等,并对引发接枝法进行了详细的讨论,为设计聚电解质润滑涂层提供参考。最后,对聚电解质润滑涂层在医疗领域的应用进行了阐述,并对其未来发展提出了展望。

Abstract

Polyelectrolytes are charged polymers that are widely used in biomedical applications. This paper reviews various polyelectrolyte lubrication coatings. This review introduces the lubrication mechanisms and polyelectrolyte classifications which are based on the polyelectrolyte brush and hydration lubrication mechanisms. Then, the polyelectrolytes are divided into three categories. The review also describes how the polyelectrolytes adhere to the substrates through physical methods, coupled grafting and initiation grafting. The initiation grafting is described in detail as a reference for the design of polyelectrolyte lubrication coatings. Finally, the potential for polyelectrolyte lubrication coatings in the biomedical field is discussed with future prospects.
