Chitosan is a polysaccharide derived from the chitin deacetylation process with wide versatility of applications in different areas such as agriculture, tissue engineering, pharmaceutical, food industry, dentistry, among others. Tissue engineering is one of the prominent areas in research involving chitosan, due to its properties such as low toxicity, bioactivity and biocompatibility. Several studies have associated chitosan with other biomaterials that have favorable biological effects to the healing process seeking the production of films with potential for biomedical application., from this perspective, this work aimed at the production and physicochemical characterization of chitosan films with the incorporation of Anacardium microcarpum Ducke extract, (“cajuí”), aiming at the production of a biomaterial for biomedical applications. Analysis of films by the techniques of: optical microscopy; contact angle; superficial tension; thermogravimetric analysis (TGA) and water absorption showed changes in the surface properties of the films that received extract, respectively, these showed higher heterogeneity, increased hydrophilic character, and greater degradation in aqueous medium than pure films.
