超支化聚酰亚胺的应用研究进展

Applications Progress of Hyperbranched Polyimide

近年来,超支化聚合物在化学、材料以及生物等领域引起了广泛的关注。超支化聚酰亚胺(HBPI)是由超支化大分子和线性聚酰亚胺结合形成的一种新型聚合物,它有独特的三维体型分子结构,高度支化的分子链分布,以及高分布密度的表面端基官能团。其独特的结构、优异的理化性能和合成及改性方法上的多样性使HBPI在许多领域具有潜在的应用。本文综述了自1999年出现超支化聚酰亚胺以来国内外在HBPI应用领域的研究进展,包括在气体分离膜、质子交换膜、光敏、光波导、荧光、介电、复合材料领域的应用研究进展,总结概述了HBPI在上述各领域的应用机理,并对HBPI的应用发展前景进行了展望。

In recent years, hyperhranched polymers has＂ drawn considerable attention in the chemistry, physics, materials, biology, and biomedicine fields for their unique properties .not shared with conventional linear polymers, which can be attributed to their highly branched structures. Hyperbranched Polyimide （HBPI） is a new type of polymers based on byperbranched macromoleeules and polyimides, which has the specific three-dimensional molecular structure, highly branched molecular chains and many end-group functional groups on the surface of the molecular. Owing to these unique structural characters, excellent physical and chemical properties, and variety in synthesis and modification, H BPI has gave rise to their potential application in many fields. The application development of HBPI from 1999 when HBPI was first prepared until now in gas permeation membranes, proton exchange membranes, photosensitive and optical waveguide materials, fluorescence, dielectric materials, and composites is reviewed in this paper. The application mechanism in every field mentioned above is summarized, and the forecast to the future developments of the application of HBPI is also discussed.
