摘要

本研究是利用溶膠凝膠法製備無機/有機混成材料，以做為光學透明玻璃膜，嘗試以苯環與無機材料共價結合的方式，以及不同比例之雙成分溶劑系統條件下的水解、縮合、成型，避免模材在加工過程的破裂現象，並利用高分子PEO長鏈對溶凝膠反應，穩定骨架結構及抑制縮合速率，達到成膜時的均勻性，並在膜材仍具有塑性(plastic state)時，搭配微結構壓模轉印技術，於玻璃表面形成轉印結構。
此類型的sol-gel材料開發，配合表面微結構加工，可以突破傳統玻璃製造技術在高溫熔融時所受的限制而保有高分子的低溫製程可行性(possibility of low process temperature)和無機材料的高透光性(highly transpareny)。

In this work, we attempted to prepare hybrid inorganic/organic composites to be an optical transparent glassy film by Sol-Gel method. The precursors of the composites combined via stable covalent bonds based on organically modified silicon alkoxides and/or functionalized organic monomer. In order to generate stable, uniform, crack-free structure, this paper focused on adjusting the ratio of two different types of solvents in hydrolysis and condensation, process. By addition of polyethylene glycol, PEG in sol-gel reaction promoted the stability of structure and suppressed the condensation rate. The polymer backbone incorporate into the inorganic/organic hybrid material.
We fabricated a copper mold has micro-pattern to be a template, coating sol on ITO-glass then transfer the surface micro-structure from the template to ITO-glass by pressing it. The technique breakthrough the limitation of traditional glass industry need to fabricate at extremely high temperature. It greatly increase the possibility of low processing temperature and high transparent optical property.
