摘要
功能梯度材料(FGM)是一种全新的非均质复合材料.聚合物梯度材料(PGM)是基体材料为高分子材料的一类功能梯度材料,因其独特的形态结构、奇特的功能和潜在的应用价值,已逐渐引起了人们的高度重视。本文综述了国内外聚合物功能梯度材料的研究现状,介绍了PGM的概念、分类、制备方法、表征方法及应用等,并对PGM未来的研究进行了展望。
Functionally Gradient Materials （FGM）is a new type of inhomogeneous composites . Polymeric Gradient Materials（PGM） is a kind of FGM based on polymer matrix. For its particular morphological structure, functions and potential applications, PGM attracted more scientists＇ attentions since it is proposed. In this paper, the present status of research on PGM are reviewed including conception, preparation, characterization and application. Moreover, the direction of development of PGM in the future is prospected.
