| 제목 | Synthesis of templated mesoporous metal oxide film using amphiphilic PVA-PMMA comb copolymer |
| 초록 | In this paper, we report a synthesis of organized mesoporous metal oxide films which have high porosity and good interconnectivity by a sol-gel process using an amphiphilic poly(vinyl alcohol)-poly(methyl methacrylate) (PVA-PMMA) comb copolymer synthesized via a one-step free radical polymerization. The PVA-PMMA comb copolymer had an amorphous, microphase-separated structure due to a very low combing degree (3 wt%) and the large fraction (25 wt%) of hydrophobic PMMA side chains, as characterized by FT-IR, NMR, DSC, XRD and TGA analysis. During the sol-gel process, an organized mesoporous structure was formed because the hydrolyzed metal precursor selectively interacted with the hydrophilic PVA backbones through coordination. Well-organized mesoporous structures were obtained for TiO2, SiO2, Al2O3, and ZrO2, but particulate structures were formed for Fe2O3 and ZnO owing to high reactivity and rapid hydrolysis. |
