摘要

本實驗以市售之三種飽和聚酯樹脂(Polyester resin)為原料，依照固定比例與溶劑(Toluene:MEK=4:1)調配成樹脂溶液，加入耦合劑(GOTMS)或是固化劑(含NCO基團類)後，以刮刀式塗佈法(Doctor blading)塗佈於PET膜上，製成FFC (Flexible Flat Cable)彈性扁平纜線(軟性排線)用之絕緣層。期望提升絕緣層與金屬導體間介面黏著力，以及利用樹脂支撐PET薄膜在高溫製程下所產生的熱收縮現象。此實驗目的可藉由提升材料品質的穩定性，耐溫性而達成。
實驗中使用微分型掃描熱卡計(DSC)、動態機械分析儀(DMA)觀察樹脂之熱力性質和玻璃轉化點(Tg)變化、熱重損失分析儀(TGA)觀察樹脂之熱裂解溫度、紅外線光譜分析儀(FTIR)觀察樹脂官能基，以及萬能試驗機測試剝離強度和拉伸強度。實驗結果顯示，添加固化劑樹脂樣品能夠增加玻璃轉移溫度(Tg)，而添加耦合劑(GOTMS)樣品能提升剝離強度。

In this study, thermal resistant staurated polyester resin is composed of three different kinds of polyester resin monomer, which are mixed with solution (Toluene:MEK=4:1) to form polyester resin solution. After adding silane coupling agent (GOTMS) or curing agent (including NCO functional group), the solution is coated by doctor blading on the PET film to make the layer of insulation for Flexible Falt Cable(FFC). The goal of this study is to improve adhesion between layer of insulation and metal conductor interface under the heat shrinkage of PET film in the high temperature production. The purposes of the study are achieved by increasing the sability and thermal resistance of the polyester resin.
Differential Scanning Calorimetry (DSC) and Dynamic Mechanical Analymer (DMA) are used to obtain thermal properties and glass transition temperatures (Tg).Thermal Gravimetric Analysis (TGA) test is used to obtain pyrolysis temperature. FT-IR is used to observe the functional group of polyester resin. The Universal Testing Machine is used to obtain adhesive and tension. This study concludes that glass transition temperature of resin can be increased by adding curing agent, the adhesion can be increased by adding coupling agent.
