TPGDASR-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

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.
