TPGDA/SR-444/VTES/ZnO有機/無機奈米複合材料合成與性質之研究

Studies on Synthesis and Properties of TPGDA/SR-444/VTES/ZnO Organic/Inorganic Nanocomposites

摘要


本研究是利用溶膠-凝膠法製備具耐熱性佳、高透光性、UV遮蔽性及符合抗靜電範圍之TPGDA/SR-444/VTES/ZnO奈米複合材料。首先將VTES經pH1.5~2.5酸性水溶液水解能得到矽醇中間物,再添加無機金屬微粒ZnO能經由有機化改質反應順利共價鍵結至有機基材上,接著將此VTES/ZnO複合物利用剩餘的活性Si-OH或Zn-OH官能基與SR-444有機壓克力單體上的活性羥基行縮合脫水反應,合成出SR-444/VTES/ZnO複合物,最後添加TAIC架橋劑及TPGDA單體與SR-444/VTES/ZnO複合物行自由基光共聚合反應產生理想程度的網狀共價鍵結結構。

This research is to synthesis TPGDA/SR-444/VTES/ZnO nanocomposite materials with good high heat resistance, good transparence in visible, UV-shielding and anti-static properties by sol-gel reaction. Firstly, the VTES was performed the silanol intermediates by hydrolysis in pH1.5~2.5 acid solution. The inorganic fillers of powder ZnO could be successfully coupled and crosslinked to organic matrices. Afterwards, the active Si-OH or Zn-OH functional groups remained on the VTES/ZnO complexes that could be covalently bonding with SR-444 acrylate monomer. Finally, TPGDA,TAIC, and SR-444/VTES/ZnO complexes were covalently bonded by UV-activated free radical polymerization to achieve cross linked structure of organic/inorganic nanocomposite.
