基于氟碳表面活性剂插层水滑石的聚酰亚胺纳米复合材料的制备与性能
Preparation and Properties of Nanocomposites Based on Polyimide and Polyfluorinated Surfactant-pillared Layered Double Hydroxide†
摘要
Abstract
Layered double hydroxide was modified with polyfluorinated surfactant via anion-exchange intercalation procedure. The nature of the interlayer anions, the morphology and the thermal stability of the fluorinated LDH( LDH-FS) were investigated by infrared spectrum, X-ray diffraction and thermogravimetry analysis. The interlayer space was expanded from 0. 76 nm to 2. 52 nm and the microenvironments with polyfluorinate phase were formed. LDH-FS based polyimide(PI) nanocomposites were prepared by the in situ polymerization and characterized. LDH-FS was well dispersed in the polyimide matrix. The gas barred, mechnical and dielectric properties of the LDH-FS / PI nanocomposites were synthetically effected by the exfoliated inorganic nanolayers and polyfluorocarbon chain.关键词
