文摘

Polyvinylidene fluoride-co-hexafluoropropylene (PVdF-HFP) composite polymer electrolyte loaded with 3-isocyanatopropyltriethoxysilane (IPTES) functionalized zirconium oxide (ZrO₂) nanoparticles is successfully synthesized and evaluated for electrochromic application. Incorporation of ZrO₂ into the polymeric substrate enhances the ionic conductivity of the electrolyte. Meanwhile, the functionalization of ZrO₂ nanoparticles with IPTES ligand enhances the electrolyte’s optical transmissivity. The amount of ligand and its time of reaction with ZrO₂ are found to affect the overall property of the electrolyte. The electrolyte exhibits a balance of low crystallinity and low ZrO₂ aggregation and agglomeration resulting to a potential next generation electrolyte for energy efficient windows.
