本研究進行以雙環戊二烯(Dicyclopentadiene, DCPD)為前驅物製備高附加價值之四甲基丙烯酸酯紫外光可硬化(UV-curable)樹脂交聯劑(D4MA),以雙酚A-甲基丙烯酸縮水甘油酯 (Bisphenol A Glycerolate (1 Glycerol/-phenol) dimethacrylate, BisGMA)為寡聚物主成分,搭配市售價格低廉且常見之米蚩酮 (Michler’s Ketone, MK)光起始劑,利用紫外光引發自由基聚合之方式硬化樹脂成膜,分別以FTIR及TGA對樹脂進行分析。實驗中分別使用自行合成出的反應性單體D4MA(交聯劑)與市面上已廣泛應用的雙官能基單體1,6-己二醇二甲基丙烯酸酯 (1,6-hexanediol dimethacrylate, HDDMA),改變光起始劑含量、改變寡聚物與反應性單體的比例以及調整兩種不同官能基之反應性單體的比例,分析其交聯時間、膠化度及熱性質以取得在應用時的最適化成分比例。
固定寡聚物與反應性單體比例,改變光起始劑含量,其膠化度會隨光起始劑的含量增加而提升,光起始劑添加量以4 wt%可獲得最佳膠化度(82%)及經濟效益;照光時間以5分鐘為最佳(曝光量:4.95 J/cm2)。固定寡聚物與反應性單體比例,改變反應性單體的種類,其膠化度會隨反應性單體所含之官能基數目增加而提升。在寡聚物與單體重量比例8:2的情形下摻混兩種含不同官能基數目之單體HDDMA/D4MA,能有效提升其膠化度達到93%。實驗結果得知當改變光起始劑含量、照光時間、寡聚物與反應性單體之比例、以及搭配兩種不同官能基之反應性單體,皆會影響高分子的轉化率及交聯密度,且由熱重分析結果得知所有交聯產物的熱裂解溫度(10%重量損失)皆高於250oC,顯示其熱安定性佳。
Owing to its environment-friendly nature, UV-curing technology has been widely used in various industries such as producing protective coatings for different materials, inks, and adhesives. The UV cured system is composed of oligomers, monomers, photoinitiator, and so on. The structures and formulations of diluent monomers and oligomers can be adjusted for particular applications such as OLED package adhesives.
In this work, we have successfully synthesized a novel tetra-functional methacrylare D4MA based on dicyclopentadiene as crosslinker. The molecular structures were satisfactorily characterized using elemental analysis, mass spectra, NMR spectroscopy and FTIR.
In the present work, a series of UV-curing resins were prepared and characterized. The photo-reactivities were also studied. The optimum curing time was about 5 min. D4MA monomer was proved to be more reactive than HDDMA monomer. The results indicate that 4wt% of photoinitiator was the most economical formulation in this UV cured system. Besides, the effect of D4MA, blended with HDDMA, on photo-reactivity was also studied. The thermal properties were investigated by TGA. All films exhibited high thermal stability with Td ranging from 295 oC to 334 oC. The results show that the optimized photo-reactivity was obtained with 80% BisGMA (oligomer), 5% HDDMA (bi-functional monomer), and 15% D4MA.
