摘要

为了提高PET薄膜的隔气性能，在功能性有机硅树脂涂料中加入了插层绢云母作为隔气材料。首先，制备了热学性能优良、交联度高的功能性有机硅树脂。其次，对绢云母进行层状插层，并用SEM和XRD对其进行表征。结果表明，该材料的片层间距为1.053 nm，与硅树脂的相容性得到改善。最后，计算了水蒸汽渗透率(WVTR)和氧气渗透率(OTR)

Excellent Gas Barrier Properties PET Film Modified by Silicone Resin/Sericite Nanocomposite Coatings

In order to improve the gas barrier properties of PET films, the intercalated sericite was used as a barrier material in the functional silicone resin coatings. Firstly, the functional silicone resin with excellent thermal properties and high crosslinking degree was prepared. Secondly, lamellar sericite was intercalated and characterized by SEM and XRD. It was found that the lamellar spacing changed to 1.053 nm, and the compatibility in silicone resin was improved. Finally, the water vapor permeability (WVTR) and the oxygen permeability (OTR) of the
