摘要註:	本研究選用兩種不同交聯速率之環氧樹脂，包括芳香族環氧樹脂 (diglycidyl ether of bisphenol A, DGEBA)及脂環族環氧樹脂(methyl-3,4-epoxycyclohexyl-carboxylate, MECC)搭配酸酐型硬化劑(methylhexahydrophthalic anhydride, MHHPA)，製作互穿式網狀結構體聚合物(interpenetrating networked polymers, IPN)，研究不同組成配方生成的網狀聚合物結構體與其表面性質之相依性。組成配方包括DGEBA/MECC/MHHPA 100/0/100, 75/25/100, 50/50/100, 25/75/100, 0/100/100，硬化溫度為110 ℃, 130 ℃, 150 ℃，硬化時間均為30 min。硬化後以FTIR、DSC、Contact angle等儀器作鑑定分析。由FTIR特徵吸收峰的強度變化，可證實兩環氧樹脂會開環與互相交聯反應。DSC數據發現交聯反應是放熱反應，放熱峰會隨DGEBA/MECC重量比增加而向高溫移動，說明MECC之交聯反應速率比DGEBA快。由硬化樣品表面水接觸角分析發現，樣品頂部及底部表面接觸角皆隨DGEBA/MECC重量比降低而降低，即頂部及底部表面親水性質皆隨DGEBA/MECC重量比降低而增加，可知MECC含量越多，此IPN的表面親水性越好，其表面的接著性質也應會越好。 In this study, two epoxy resins with different crosslinking reaction rates were chosen for the preparations of interpenetrating networked polymers (IPN) and were investigated on the dependence of their surface properties on compositions of epoxy resins using FTIR, DSC, and contact angle analyzer for chracterizations. The epoxy resins included diglycidyl ether of bisphenol A (DGEBA) and methyl-3,4-epoxycyclohexyl-carboxylate (MECC), both using methylhexahydrophthalic anhydride (MHHPA) as the curing agent. The compositions included DGEBA/MECC/MHHPA 100/0/100, 75/25/100, 50/50/100, 25/75/100, and 0/100/100, crosslinking at 110 ℃, 130 ℃, and 150 ℃ for 30 min. FTIR spectra confirmed the occurrence of crosslinking reactions and formation of IPN structures. DSC data found that the crosslinking reactions were exothermic and the exothermic peaks shifted to higher temperatures with higher DGEBA/MECC weight ratios, indicating that the reaction rate of MECC was higher than that of DGEBA. The measurements of water contact angles of the cured IPN found that the contact angles at top and bottom of the cured samples both decreased with decreasing DGEBA/MECC weight ratios, an indication that higher contents of MECC in composition would give more hydrophilic surface properties and might lead to higher adhesive strengths.
