由於不同軟硬鏈段比例所組成的熱塑性聚氨基甲酸酯(Thermoplastic polyurethane, TPU)其物理性質及化學性質而也有所不同，因此熱塑性聚氨基甲酸酯被廣泛的應用在各個領域中。熱塑性聚氨酯因為具有較高的生物相容性及血液相容性，且物化性優良，所以在生醫的領域中也是常見的生醫材料。本研究主要是利用電漿改質技術將熱塑性聚氨酯Tecoflex○R93A、60D及68D進行表面處理，並利用接觸角測量儀測量熱塑性聚氨酯的表面親水性，結果顯示當電漿時間為5分鐘時93A、60D及68D的接觸角的變化量趨於相似，而電漿處理完一天後仍有較高的接觸角變化量，硬度最高之材料回升最不明顯。在白蛋白的測試結果中可以發現不同的電漿時間會影響白蛋白的貼附濃度，且薄膜成形時的接觸面也會影響薄膜的軟硬鏈段的分佈，經電漿改質後其白蛋白的濃度也會因接觸面而有所不同的變化。

Because the different ratio of soft and hard segments composed of thermoplastic polyurethane(TPU) that have different physical properties and chemical properties, a result thermoplastic polyurethanes are widely used in various areas. Thermoplastic polyurethane has high biocompatibility and blood compatibility , and has excellent physical and chemical properties , so common in the areas of biomedical biomaterials. This mainly study the modified thermoplastic polyurethane surface treatment by the plasma , and measuring the surface of the thermoplastic polyurethane hydrophilic by using a contact angle measuring instrument. The results showed , when the plasma time of 5 mins, 93A, 60D and 68D which contact angle change amount tends to similarity, the contact angle still have higher changes amount by plasma treatment after a day. The highest hardness of the material is most has not obvious rebound in. In the test results, different plasma time can affect the of protein attached concentration, film forming a contact surface will affect the distribution of the hard and soft segments in the film. By plasma modification of the thermoplastic polyurethane that protein concentration have different changes in the contact surface.
