Disponível em:https:/doi.org/10.1111/jfs.13021.https://repositorio.ufrn.br/handle/123456789/64359This study evaluated the effect of adding beeswax on the hydrophobicity of biodegradablefilms produced from cornstarch. The respective films were produced from a standardformulation incorporating beeswax, keeping its concentration constant, analyzing the contactangle, colorimetry and thickness of the films. The method used for production was molding,in which the film-forming solution was prepared, poured into a mold and subjected to dryingunder controlled temperature conditions. The results indicated that the moderate incorporationof beeswax increased the hydrophobicity of the films, evidenced by sampling the contactangle. In addition, it was found that the wax influenced the color and thickness of the films,modifying their optical and mechanical properties. These results suggest that beeswax can actas an effective modifier, enhancing some characteristics of biodegradable films and makingthem more suitable for various applications, from the commercialization of environmentallybeneficial packaging and/or sustainable applications in various sectors, mainly in agriculture.pt-BRAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/filmes biodegradáveishidrofilicidadesustentabilidade.bachelorThesisENGENHARIAS
