本研究係以含有飽和氯化鐵/甲醇潛溶劑之PMMA試片為長晶基材，通入飽和碳酸氨形成碳酸鐵結晶，製成高分子基複合材料，本文將分PMMA於潛溶劑中的質傳行為、質傳試片的長晶與結晶試片以及結晶試片烘烤後的性質分析四部分做探討。實驗結果顯示PMMA於氯化鐵/甲醇潛溶劑之質傳過程為吸熱反應，氯化鐵對Case I擴散之擴散係數、Case II擴散之擴散速率、Case I擴散活化能及Case II擴散活化能有不同影響試片，溶漲界面在會合前會有明顯膨脹之現象。質傳後長晶試片中，碳酸鐵結晶形成由邊緣兩側開始，其晶粒成長大小由邊緣到試片中心有縮小的趨勢。對可見光及紫外光穿透光譜分析，氯化鐵/甲醇潛溶劑飽和質傳及長晶試片，當質傳溫度及濃度較高時，在1240 cm-1、1380 cm-1有產生新的吸收峰，烘烤過後整體的吸收峰強度比烘烤試片前，明顯強上許多。另外，氯化鐵/甲醇潛溶劑系統長晶試片，隨質傳溫度及質傳濃度的增加，試片之玻璃轉換溫度有上升的趨勢。氯化鐵/甲醇潛溶劑飽和質傳及長晶試片烘烤後，隨著質傳溫度及濃度較高時，會增加PMMA材料的脆性。氯化鐵/甲醇潛溶劑系統長晶試片烘烤後，隨質傳濃度的增加，試片之硬度有上升的趨勢。 This research was proposed to study on the crystallization substrates which have been mass transport of methanol mixed with ferric chloride hexahydrate (FeCl3‧6H2O) in poly(methyl methacrylate) (PMMA) and react with ammonium carbonate to produce iron carbonate crystallization. This research will be divided into four portions to study on the mass transport of cosolvent in poly(methyl methacrylate)、the crystallization condition of the substrates vs. the properties of the crystallization specimen and the character after baking. The experimental results indicate that the mass transport of this two cosolvent in poly(methyl methacrylate) (PMMA) is an endothermic process. The two saline have different influence on the diffusion coefficient for CaseⅠ, the diffusion velocity for CaseⅡ, the activation energy of diffusion coefficient in CaseⅠtransport and the activation energy of diffusion velocity for CaseⅡ.The FTIR spectrum of the specimen with the iron carbonate crystallization shows the new absorption peak at 1240cm-1and 1380 cm-1. In addition, the glass transition temperature (Tg) of the specimen with iron carbonate crystallization will rise as the increase of mass transport temperature and concentration. After backing, as the quality spreads temperature and when the consistency is higher, brittleness of PMMA material is increasing.
