In this study, three isocyanate monomer coated with n-eicosane of the phase-change materials in order to interface polymerization microencapsulated phase change materials (PCM), and take advantage of plasma modification of polyester fabric (PET) surface, so that the surface of free radicals, and take advantage of plasma treatment of polyester fabric surface free radicals in chemical bonding methods and microencapsulated phase change materials PCM on the grafting reaction of functional group generated. In order to improve traditional technologies do not use any intermediate and film to reach microencapsulated PCM with polyester fabric PET coating of the results, and the use of DSC heat absorption test, test the absorption heat and reproducibility. In the experiment that, after three isocyanate monomer coated with n-eicosane of microencapsulated phase change materials by using DSC heat absorption tests carried out would not affect them, and then 4000 times the SEM observation of 500,1200 , 3000rpm rotational speed down the size of different 1000,10.35,0.4 μm respectively, and the appearance type of good, still has the nature of heat absorption. The use of FTIR to plasma treatment of polyester fabric PET before and after grafting, the use of FTIR to observe the changes before and after the functional groups, found that only PU and CH2 only some of the functional groups OH, indirect proof of polyester fabric PET by the plasma after treatment with microencapsulated PCM of the effect of chemical grafting, and graft after the completion of the reproducibility of heat absorption with non-grafted prior to roughly the same heat absorption without the need to do their comparison, on behalf of grafted micro - Capsule not been destroyed.
本研究以界面聚合法製備利用聚胺酯(PU)包覆正二十烷之相變化材料微膠囊,並利用電漿改質聚酯織物(PET)表面使其表面產生自由基,經電漿處理後聚酯織物表面上之自由基以化學鍵結方法與相變化材料(PCM)微膠囊上之官能基產生接枝反應。以改良傳統技術,不利用任何中間體與薄膜,達到PCM膠囊與織物PET塗佈之效果,並利用DSC測試其吸放熱與再現性。實驗得知,經三異氰酸單體聚合後包覆正二十烷之微膠囊,利用DSC進行吸放熱測試時不會有所影響。在SEM下以4000倍觀察1200rpm轉速下其平均粒徑為10.35±0.37μm且外觀成型性良好,並仍具有吸放熱之性質。利用FTIR觀察電漿處理織布PET接枝前後之官能基變化,發現只有三異氰酸單體聚胺酯才會有的OH與CH2之官能基,間接證明織布PET經電漿處理後與PCM微膠囊產生化學接枝之效果,且接枝完成後吸放熱之再現性與未接枝前之吸放熱大致相同,代表接枝後膠囊PCM膠囊沒有被破壞。
