| 摘要: | 本研究主要利用溶膠-凝膠法(Sol-Gel)將甲基三甲氧基矽烷(MTMS)、鈦酸丁酯(TTB)與雜環系偶氮染料合成一系列噻二唑偶氮染料之混成材料。先利用濃鹽酸、甲酸與硫代胺脲加熱迴流方式反應合成中間體3-胺基-1,3,4-噻二唑，將其視為偶合鹽，而與對-硝基苯胺當作重氮鹽來進行偶合反應，製得雜環系噻二唑偶氮染料。將製得之雜環系噻二唑偶氮染料與固定比例之乙烯基三乙氧基矽烷VTES配合不同比例的MTMS/TTB產生水解聚縮合反應，製得SiO2/TiO_2與噻二唑偶氮染料之混成材料。聚對苯二甲酸乙二酯(PET)和聚對苯二甲酸丙二酯(PTT)織物進行染色加工，再藉由SEM觀察PET與PTT加工織物其表面形貌。加工後之PET與PTT織物分析其接觸角、上色性、均染性與透氣性等各項物性。
A series of some novel hybrid materials prepared via sol-gel process has been synthesized from methyltrimethoxysilane as precursors comprising with heterocyclic 1,3,4-thiadiazole azo dyes. The start material 1,3,4-thiadiazole was synthesized from formic acid and thiosemicarbazide in reflux to get the 1,3,4-thiadiazole. The 1,3,4-thiadiazole regards as coupling component were coupled with p-nitro aniline aniline as diazo component at ice bath, to give the heterocyclic 1,3,4-thiadiazole azo dyes. SiO_2/TiO_2/ thiazole azo dyes hybrid materials were synthesized via sol-gel process with precursor system. Alternatively, the heterocyclic 1,3,4-thiadiazole azo dyes processed with hydrolysis-condensation reaction by the constant ratio of vinyltriethoxysilane and methyltrimethoxysilane and titaninm-n-butoxide in appropriate proportion under catalyst. The surface morphology of processed PET and PTT fabrics was evaluated by scanning electron microscopy (SEM). The water contact angle, color strength, evenness, and air permeability characteristics of the as-prepared dyed PET and PTT fabrics were subsequently evaluated. |
