    摘要: 本研究以浸漬相轉換法製備生物可分解性高分子-聚丁基烷酯(Poly(hydroxybutyrate;PHB)之多孔型薄膜,並應用電漿誘導接枝將薄膜表面改質使薄膜表面功能化。PHB薄膜之製備以氯仿為溶劑,乙醇為非溶劑。首先製作ethanol-chloroform-PHB成膜系統之相圖,利用其選定適當製膜液組成,並藉由改變製膜液之配製溫度,製備不同結構之薄膜。薄膜之孔隙結構、結晶性、機械強度、滲水性等皆加以分析探討,以了解這些物性與製膜程序之關係。其次我們以電漿誘導聚合法將聚丙烯酸接枝在PHB薄膜表面上,並由改變接枝條件如電漿處理時間、電漿功率、接枝反應時間、單體濃度等獲取最佳接枝條件,結果顯示最大接枝量可達0.48 mg/cm2。
    In this research, porous membranes of a biodegradable polymer, poly(hydroxybutyrate), were synthesized and the surfaces of which were modified by plasma-induced polymerization so as to engender functionality to the membranes. Chloroform and ethanol were used as the solvent and nonsolvents, respectively, for membrane formation by the immersion precipitation method. Phase diagram of the ethanol-chloroform-PHB system was constructed; thereby appropriate dope composition was selected. Membranes with different structures were then prepared by changing the dope preparation temperature. The porous structure, crystalline character, mechanical strength, and water wettibility of the formed membranes were studied to understand the relationship between these properties and the membrane formation process. Plasma-induced polymerization method was employed to graft poly(acrylic acid) on the membrane surface. Various variables, viz., plasma treatment time, plasma power, grating reaction time, and monomer concentration were investigated and the largest grafting yield was found to be 0.48 mg/cm2 under optimal conditions.
