Abstract:	主要是利用溶膠-凝膠法將噻唑染料、乙烯基三乙氧基矽烷、四乙氧基矽烷與奈米銀合成噻唑偶氮染料之混成材料。先利用苯乙醯、硫代尿素及碘以隔水加熱迴流方式反應合成噻唑中間體。將其視為偶合鹽，與對-硝基苯胺當成重氮鹽來進行偶合反應，製得噻唑偶氮染料。利用一定比例的乙烯基三乙氧基矽烷與不同比例的四乙氧基矽烷及不同比例的奈米銀進行反應，製成奈米銀/二氧化矽/雜環噻唑染料混成材。聚對苯二甲酸乙二酯(PET)織物進行染整加工，再藉由SEM 觀察PET 加工織物其表面形貌。加工後之PET 織物分析其接觸角、上色性、透氣性與抗菌性等各項物性。 A series of some novel nano silver/silica/thiazole azo dyes hybrid materials prepared via sol-gel process with vinyltriethoxysilane as precursor has been synthesized from nano silver and tetraethoxysilane with heterocyclic thiazole azo dyes. The start material thiazole was synthesized from thiourea, acetophenone derivative and iodide to get the thiazole intermediate. The 4-phenyl thiazole regards as coupling component were coupled with p-nitro aniline as diazo component at ice bath, to give the heterocyclic thiazole azo dyes. Alternatively, the heterocyclic thiazole azo dyes processed with hydrolysiscondensation reaction by the constant ratio of vinyltriethoxysilane and nano silver and tetraethoxysilane in appropriate proportion under catalyst. The surface morphology of processed PET fabrics was evaluated by scanning electron microscopy (SEM). The water contact angle, color strength, air permeability and antibacterial characteristics of the hybrid materials processed PET fabrics were subsequently evaluated.
