Chitin has proven to have a good mechanical and electrical properties to be used in making piezoelectric thin films. However, due to the restriction in solubilizing chitosan in many solvents, there is increasing interest in exploring the used of chitosan in producing thin films. Chitosan, compared to chitin, can be easily solubilized in certain dilute acids. Chitosan that has been extracted from fungal biomass can be used for the fabrication of biomaterial thin films. There are different ways that can be used to fabricate a thin film such as electrospinning, spin-coating, solvent casting and also the hot press technique.

用于制备压电薄膜的微生物壳聚糖

几丁质已被证明具有良好的机械和电气性能，可用于制造压电薄膜。然而，由于壳聚糖在许多溶剂中溶解的限制，人们越来越关注探索壳聚糖在生产薄膜中的用途。与几丁质相比，壳聚糖可以很容易地溶解在某些稀酸中。从真菌生物质中提取的壳聚糖可用于制造生物材料薄膜。有不同的方法可用于制造薄膜，例如静电纺丝、旋涂、溶剂浇铸以及热压技术。
