Among various materials for 3DPCs fabrication, SiO2-based polymers have drawn great interest due to their high refractive index, excellent mechanical properties, and good thermal stability. In this project, we aim to fabricate SiO2 polymer 3DPCs with a simple and cost-effective method and investigate their structural properties.Objectives:1. To synthesize SiO2-based polymers by sol-gel method.2. To fabricate SiO2 polymer 3DPCs through self-assembly and template fabrication processes.3. To analyze the structural properties of SiO2 polymer 3DPCs by SEM, XRD, and FTIR.4. To investigate the optical properties of SiO2 polymer 3DPCs by UV-Vis spectroscopy.Methodology:1. Synthesis of SiO2-based polymers: Tetraethyl orthosilicate (TEOS) and other reagents will be used to synthesize SiO2-based polymers by sol-gel method.2. Fabrication of SiO2 polymer 3DPCs: Two methods will be employed, self-assembly and template fabrication processes, to fabricate SiO2 polymer 3DPCs.3. Structural analysis: SEM will be used to observe the morphology of SiO2 polymer 3DPCs. XRD and FTIR will be used to analyze the crystal structure and chemical composition of the samples.精品文档---下载后可任意编辑4.
