碩士 === 明志科技大學 === 機械工程系機械與機電工程碩士班 === 102 === In this study, the main goal is to dope D-glucose、DBTA、liquid crystal(E7) into different sol-gels though the sol-gel process and by thermal polymerization induced reaction to produce a optical micro porous glassy substrate. The sol-gel process contains various parameters, which could influence the synthesis of between the optical materials and sol-gel substrate. As a result, this thesis has discussion over changing the composites of sol-gel、the control of temperature in process and the selection of containers and observation on different optical rotary dispersions and birefringence of sol-gel matrix doped with D-glucose, DBTA and the liquid crystal(E7). In this study, the sol-gel matrix consists of tetraethylsilicate(TEOS)/n-octyltriethoxysilane(C_8TEOS)/n-propyltrimethoxysilane(n-propyl-TriMOS)/3,3,3-trifluoropropyltrimethoxysilane(TEP-TriMOS). D-glucose and DBTA is respectively doped into 3 types of sol-gels matries: TEOS/C_8TEOS、n-propyl-TriMOS/TEOS/C_8TEOS 、 TEP-TriMOS/TEOS/C_8TEOS though the temperature process control to produce optical-rotary microporous glassy material. The experiment is conducted by using Stokes Polarimeter to receive rotation angle γ. The result demonstrates that rotation angle γ is upwards as concentration of D-glucose and DBTA doped into sol-gels increase. Moverover, this study also dopes liquid (E7) into TEOS/C_8TEOS sol-gel matrix to produce birefringent microporous glassy material though which to observe the birefringence. The goal of this study is mainly to develop a method without need to dope metal powder and silica and instead, by using simple and low cost sol-gel process in application for fabricating optical components in MEMS process.
