采用流延成膜法制备载香茅精油壳聚糖膜和纯壳聚糖膜,并对膜的结构特征、力学性、吸水透气性和抑菌性进行比较分析。结果表明:壳聚糖、香茅精油和吐温80三者的相容性良好,所制得的载香茅精油壳聚糖膜结构均一、平整度较好,具有一定的力学性能,吸水透气性良好,广谱抗菌效果明显,有望成为一种新型的医用材料并得到广泛应用。 The cast-oil-forming chitosan membrane and pure chitosan membrane were prepared by casting method. The structural characteristics, mechanical properties, water absorption, air permeability and bacteriostasis were comparatively analyzed. The results showed that the compatibility of chitosan, citronella oil and Tween 80 was good. The obtained chitosan elctrophil chitosan membrane had uniform structure, good flatness and certain mechanical properties. Good sex, broad-spectrum antibacterial effect is obvious, is expected to become a new type of medical materials and has been widely used.
