Multi-functionalization by Thin Film Formation Using the Ion Beam Mixing Method on Polymer

我们尝试采用各种方法来保护聚合物材料不受环境降解的影响，并在其表面提供功能。聚醚酰亚胺(PEI)树脂具有优异的力学性能、热学性能、电学性能和抗裂性。因此，它的应用正在扩展到电子电气设备和医疗设备的精密部件。在医疗领域，必须在医疗后对工具进行重复的水洗或射线照射，以防止细菌感染。从这些角度来看，本研究旨在评估PEI树脂在水吸收和紫外线(UV)照射下的降解行为。并针对PEI树脂官能化程度较高的缺点，尝试了真空气相沉积和离子束混合辅助气相沉积两种方法来形成薄膜。还考察了薄膜形成对吸水特性的影响。

We have tried to apply various methodes to protect polymeric materials against the environmental degradation, and to provide functions on their surface. The polyetherimide (PEI) resin has excellent characterristics in mechanical, thermal, and electrical and in crack resistance. Thus, its applications are being extended to precision components for electric and electronic devices and for medical equipment. In the area of medical care, the repetition of water wash or ray irradiation on tools must be applied after medical treatment in order to prevent bacterial infection. From these view points, this study is being made for evaluating the degradation behavior or the PEI resin as a result of water absorption and UV (ultraviolet) ray irradiation. And for the puropse of higher functionalization of PEI resin, the formation of thin film has been tried as a method the surface coating by vacuum vapor deposition and assisted vapor depoition using the ion beam mixing methods. The effect of thin film formation upon water absorption characteristics was also examined.
