- 摘要：The paper represents the situation of internal friction researches for polymer blends and composites,and analyses specially the correlation between internal friction behavior and microstructure.It is found that both intermolecular interaction in polymer blends and composite interface interaction are reflected by internal friction features at molecular level,therefore,internal friction measurement is sensitive probe for characterizing supermolecular structure in polymer blend and composite interface microstructure.The intrival problem needed to be considered in the future includes the studying of internal friction mechanism,establishing appropriate model to describe the internal friction behavior and giving definite physical meaning for characteristic parameters.关键词：Polymer blends;Composites;Internal friction analysis

发布时间：2022-09-18 - 摘要：One must illustrate the target of polymer science as the starting point of a series of polymer physics lectures.Usually,we pay attention to the chemical and spatial structures of the polymers,but not emphasize their general features that are corresponding to the physical properties. At present,we focus on the chain-like feature of polymers,and illustrate it through two generalities and three individualities of polymer structures,accompanying with the physical properties which are dominated by these structural features.关键词：Polymer science;Chain-like Structure;Structure and Property Relationships
