The effect of low-temperature plasma treatment on the surface properties of thermoplastic starch film (TPS) was investigated. The surface layer (SL) modification of polymeric materials is mainly carried out to improve wettability and adhesive properties and to increase surface cleanliness. TPS was modified in an air atmosphere under either atmospheric or reduced pressure. The process parameters for modifying the SL of TPS were determined based on wettability assessment using a goniometer, geometric structure using scanning electron microscopy (SEM), and the degree of oxidation (O/C ratio) using X-ray photoelectron spectroscopy (XPS). Additionally, the effect of plasma treatment on TPS film sterilization was investigated.
研究了低温等离子体处理对热塑性淀粉薄膜（TPS）表面性能的影响。聚合物材料的表面层（SL）改性主要是为了改善润湿性和粘附性能，并提高表面清洁度。TPS在空气气氛中于常压或减压下进行改性。基于使用测角仪的润湿性评估、使用扫描电子显微镜（SEM）的几何结构以及使用X射线光电子能谱（XPS）的氧化程度（O/C比）来确定TPS表面层改性的工艺参数。此外，还研究了等离子体处理对TPS薄膜杀菌的影响。
