本論文是利用含氫矽油改質技術進行陽離子型光固化技術之研究，目的在製備矽氧型的離型劑，主要探討將環氧基導入聚矽氧樹脂，合成出含環氧之聚矽氧樹脂(E-PDMS)，期望降低離型劑與PET的剝離強度並且探討表面特性之變化。本實驗製程中是利用環氧樹脂吸收365nm波長的紫外光後發生交聯固化。本實驗利用傅立葉紅外線光譜儀(FT-IR)及核磁共振分析儀(H-NMR)分析其化學結構，藉由紫外光/可見光譜儀(UV-vis)測穿透率，並以熱分析儀(TGA)測試其熱性質差異。藉由水接觸角量測儀、剝離強度測試儀等分析探討固化後離型劑表面性質的變化。
由FT-IR與1H-NMR可看出矽氫基官能基被環氧官能基完全消耗，成功合成出含具環氧官能基的E-PDMS 樹脂。藉由接觸角量測儀分析可得知固化後E-PDMS樹脂，其疏水性有提升，並利用OWRK method和Wu method所計算出表面自由能有降低的趨勢。在不同改質矽油中，含氫比例為H-16的剝離強度為37(g/cm)，而具有最佳的耐剝離效果。
綜合上述實驗結果，矽油經改質降低含氫量可提升表面之離型力以及耐剝離效果。

In this investigation, uv-curing processing was conducted to study the H-PDMS modification, The purpose is to prepare the release agent of silicon with high release force and focus on the epoxy groups to the polydimehtylsiloxane to synthesize polydimethylsiloxane which contains epoxy groups (E-PDMS).We anticipate improving the peel intensity and examining the change of surface characteristic of PET and release layer. The epoxy resin was cross-link at ultraviolet of 365nm.The investigation examined the structures of the polysiloxanes of epoxy was determined by FT-IR and H-NMR, The transmission of the epoxy film was measured by UV/vis spectrometer and the thermal properties was determined by TGA. The surface characteristics of release layer have been analyzed by contact static angle measurement.
The structure of H-PDMS modification was investigated by FT-IR and 1H-NMR which shows epoxy groups were succseefully connected, based on contact angle analysis, the hydrophobicity of release layer surface could be greatly improved by reduced the hydrogen content of H-PDMS, In addition, the contact angle results based on OWRK method and Wu method revealed that surface free energy would increase after H-PDMS modification, The results show that H-16 has the best release intensity(37g/cm)and also has strongest peel resistance.
As a result, the release intensity and high durability of peel would increase through decrease the hydrogen content of H-PDMS.
