聚合物结构与气体渗透性能研究

Study on Polymer Structure and Gas Permeability

随着包装产业的发展,聚合物在包装产业中的地位越来越重要。相比于传统的包装材料(如玻璃和金属),聚合物是可渗透的。本文介绍了小分子在本征型聚合物中的渗透机制,重点阐述了聚合物的链结构、聚集态结构与其阻隔性能的关系。其中聚合物的链结构主要包括结构单元的化学组成,交联,空间构型,聚合物链的构象,聚合物链的柔顺性;聚合物聚集态结构主要包括聚合物结晶,取向。

With the development of packaging industry , the status of polymer in the packaging industry is becoming increasingly important.Compared to traditional packaging materials （such as glass and metal）, polymer is permeable.A small molecule permeation mechanism in the polymer was described focused on the relationship between intrinsic polymer chain, aggregation structure and its relationship barrier properties .Wherein the polymer chain structure main comprised structural units of the chemical composition , cross-linking , the spatial configuration of the polymer chain conformation , the flexibility of the polymer chain , polymer aggregation structure included a crystalline polymer orientation .
