摘要
　　　本研究利用塊狀聚合法來製備乙烯酯(vinyl ester)/二氧化鈦(titanium oxide)之奈米複合材料，製備時以不同含量重量百分比之二氧化鈦進行聚合，實驗中除比較添加不同含量二氧化鈦的乙烯酯，另外探討直接添加未經(jīng)改質(zhì)的奈米二氧化鈦(non-modified TiO2)和加入以MPS改質(zhì)的奈米二氧化鈦(modified TiO2)之靜態(tài)機械性質(zhì)(抗張強度與模數(shù)、耐衝擊強度和硬度)、動態(tài)機械性質(zhì)(DMA)、熱性質(zhì)(TGA、DSC)及物理性質(zhì)提昇與改質(zhì)乙烯酯性質(zhì)程度差異。
　　　研究結(jié)果得知，經(jīng)由傅立葉紅外線光譜(FTIR)分析，證實奈米二氧化鈦已成功改質(zhì)。以XRD觀察乙烯酯/二氧化鈦奈米複合材料，顯示改質(zhì)前後的二氧化鈦並不會改變其結(jié)晶型態(tài)。以SEM觀察改質(zhì)對奈米二氧化與乙烯酯之間的結(jié)合力差異，得知改質(zhì)過二氧化鈦與乙烯酯結(jié)合性較佳。機械性質(zhì)方面，得知複合材料的抗張強度和耐衝擊強度測試皆會隨者奈米二氧化鈦的添加變硬變脆而下降，導(dǎo)致未改質(zhì)二氧化鈦的機械性質(zhì)優(yōu)於改質(zhì)的二氧化鈦。動態(tài)機械性質(zhì)方面，Tg點隨者添加量的上升而上升。在熱性質(zhì)方面，隨著奈米二氧化鈦添加量的增加，耐熱性效果提升更為顯著。

Abstract
　　　In this paper we use bulk polymerization to produce nanocomposites of vinly ester /titanium oxide. The synthesis of nanocomposites materials include vinyl ester, and titanium oxide (include non-modify and modify). To investigate the improvement on the static mechanical and physical properties, dynamic mechanical analyzer (DMA), heat properties of vinly ester /titanium oxide nanocomposites. The static mechanical properties include tensile strength and modulus, impact strength and hardness. In the heat properties include thermogravimetric analyzer (TGA) and different scanning calorimeter (DSC).
　　　Different functional groups were grafted on the titanium oxide by Fourier transform infrared spectrometer(FTIR). The crystal structure of vinly ester /titanium oxide nanocomposites was determined at XRD and has no significant peak as that of pure vinly ester. It is observed that the modification influenced bound force between vinyl ester and titanium oxide by SEM, and discove modified titanium oxide best than non-modified titanium oxide of associativity. In the mechanical properties, the results had been down for tensile strength and impact strength because the Material has been Stiffening and Changes crisp. The non-modified titanium oxide was better than modified titanium oxide in the vinly ester /titanium oxide nanocomposites. The glass transition (tan δ peak) had been up, when vinyl ester filled of titanium oxide. In the heat properties, concentration of titanium oxide was refledted in amarked increase of heat-resistant.
Keywords: vinyl ester, titanium oxide, nanocomposites
