摘要

研究壳聚糖薄膜的表面微观结构对接触角的影响。选择壳聚糖和再生壳聚糖制备无增塑剂的薄膜进行试验。采用基于欧洲药典的固滴法测定接触角。由于薄膜的制作方法，接触角的测量是在薄膜的顶部和底部表面进行的。扫描电镜证实，对于壳聚糖或再生壳聚糖薄膜，制备方法对薄膜顶部和底部的润湿性差异有轻微影响。另一方面，纤维素膜的顶部和底部的润湿性根据膜的侧面变化很大。壳聚糖和纤维素膜均具有均匀的结构。在纤维素膜中，样品的顶部和底部的微观结构存在差异，这是影响接触角从而影响表面润湿性的一个因素。

EFFECT OF CHITOSAN FILM SURFACE STRUCTURE ON THE CONTACT ANGLE

The aim of this study was to evaluate the influence of the surface microstructure of chitosan films on the contact angle. Films without plasticising additives made of chitosan or regenerated chitosan were selected for the tests. A sessile drop method based on the European Pharmacopoeia was used to determine the contact angle. Due to the method of film production, the contact angle measurements were made on both the top and bottom surfaces of the film. For chitosan or regenerated chitosan films, the method of preparation slightly affected the difference in wettability between the top and bottom of the films, as confirmed by scanning electron microscopy. On the other hand, the wettability of the top and bottom of cellulose films varied greatly depending on the side of the film. Both chitosan and cellulose films had a homogeneous structure. There were differences in the microstructure between the top and the bottom of the sample in the cellulose film, a factor that affected the contact angle and thus the wettability of the surface.
