The Effect of Silane Coupling Agent on the Texture and Properties of In Situ Synthesized PI/SiO Nanocomposite Film.

PI/SiO composite films have been prepared by using in situ polymerization. The influences of the dosage of silane coupling agent (KH-560) on the structure and performance of PI/SiO composite film have been investigated. The results show that in the components without KH-560, the addition of SiO decreases the transmittance of the sample.

Synthesis and Properties of Polyimide Silica Nanocomposite Film with High Transparent and Radiation Resistance.

In order to prepare flexible glass cover sheet materials suitable for space solar cells, fluorinated diamine 2,2'-bistrifluoromethyl benzidine (TFDB) and fluorinated dianhydride 4,4' (hexafluoroisopropyl) diphthalic dianhydride (6FDA) as the monomer, polyimide (PI)/SiO composite film was synthesized by in situ polymerization, and the influence of coupling agent and SiO nanoparticle content on the film structure and properties was studied. The results show that PI synthesized from fluorine-containing monomers has better light transmittance, and the highest transmittance can reach 91.4%.
