Albumin/gelatin gel (AG) properties are studied with an innovative cold‐plasma‐treatment‐based technique. Gel films are produced in situ on polyethylene terephthalate (PET) plates previously treated by gas (O₂, air and Ar) cold plasma. After detaching the films from the surface, the contact angles of probe liquids are measured and wettability studied, based upon the induced changes of AG surface free energy. The effect of gelatin concentration in the AG is analysed. Oxygen‐cold‐plasma‐treated PET plates induce outstanding changes in wetting properties. Optical profilometry is used for the characterisation of surface topography. Dynamic oscillatory measurements help check for mesoscopic changes. The latter technique allows shaping of gel sample stiffness. The findings support a new methodology for biomaterials/biopolymer activation when unable to be exposed to the plasma working conditions.

在低温等离子体处理的聚对苯二甲酸乙二醇酯板上凝胶化的白蛋白/明胶膜的表面改性

白蛋白/明胶凝胶（AG）的特性已通过创新的基于冷等离子体处理的技术进行了研究。凝胶薄膜是在预先用气体（O ₂）处理过的聚对苯二甲酸乙二醇酯（PET）板上原位生产的，空气和Ar）冷等离子体。从表面上剥离薄膜后，基于AG表面自由能的诱导变化，测量探针液体的接触角并研究润湿性。分析了AG中明胶浓度的影响。经氧冷等离子体处理的PET板可引起润湿性能的显着变化。光学轮廓测定法用于表征表面形貌。动态振荡测量有助于检查介观变化。后一种技术允许凝胶样品刚度的成形。这些发现为无法暴露于等离子体工作条件下生物材料/生物聚合物活化的新方法提供了支持。
