本研究將具生物分解性之纖維素（Cellulose）以丙烯酸醯氯(methacryloyl chloride)改質，得到含甲基丙醯酸酯之改質纖維素—(Cell-MMA)。以Cell-MMA與環氧樹脂—DGEBA (diglycidyl ether bisphenol A)、硬化劑─己二胺(hexamethylene diamine, HMDA)，混合均勻後，在過氧化苯甲醯酯(benzoyl peroxide, BPO)的存在下加熱，使DGEBA/HMDA與Cell- MMA分別進行逐步加成及自由基架橋反應，形成互穿網狀(interpenetrating polymer network, IPN) 纖維素/環氧樹脂混成材料— Cell-MMA/DGEBA/HMDA（CMDH-I）。以熱示差掃描卡量計、熱重分析儀測試混成材料之熱性質，同時亦將以培養基混合進行褐腐菌(Laetiporus sulphureus)之生物分解試驗，以探討其生物分解效果；其他有關混成材料之機械性質也做深入探討。

A homogeneous mixture of modified cellulose, cell-MMA, obtained by reaction of cellulose with methacryloyl chloride, with diglycidyl ether bisphenol A (DGEBA)/hexamethylenediamine ( HMDA) epoxy resin was prepared. Cell-MMA and DGEBA/HMDA underwent respective free radical and poly-addition polymerization simultaneously to afford a biodegradable hybrid, Cell-MMA/DGEBA/HMDA, with interpenetrating network (IPN) structure when the mixture was heated at 60℃ in the presence of BPO. After measuring the mechanical and thermal properties by DSC, TGA, and Tensilon. The IPN-structured hybrid was submitted to biodegradation tests by Laetiporus sulphureus.
