Resumo: In the present study, polyvinylpyrrolidone films containing amino acid-based surfactant, namely, sodium lauroyl sarcosinate (SLS), were prepared by casting method. The obtained films (PVP/SLS) were characterized by means of attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), optical properties, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and moisture absorption (MA). ATR-FTIR spectra of PVP/SLS films showed the main bands of PVP. The opacity of PVP films increased with the addition of SLS. Furthermore, moisture absorption of PVP/SLS films were higher than the pristine PVP film. TGA curves displayed that the thermal stability of PVP film decreased after the incorporation of SLS. DSC curves indicated that SLS can be used as plasticizer for PVP.

Os filmes obtidos (PVP/SLS) foram caracterizados por espectroscopia de infravermelho por transformada de fourier com refletância total atenuada (ATR-FTIR), propriedades ópticas, análise termogravimétrica (TGA), calorimetria exploratória diferencial (DSC) e por absorção de umidade (AU). Os espectros ATR-FTIR dos filmes de PVP/SLS mostraram as principais bandas do PVP. A opacidade dos filmes de PVP aumentou com a adição de SLS. Além disso, a absorção de umidade dos filmes de PVP/SLS foi maior do que o filme de PVP. As curvas TGA mostraram que a estabilidade térmica do filme de PVP diminuiu após a incorporação do SLS. As curvas de DSC indicaram que SLS pode ser usado como plastificante para PVP.Universidade Federal de Viçosa - UFV2023-06-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1599710.18540/jcecvl9iss5pp15997-01eThe Journal of Engineering and Exact Sciences; Vol. 9 No. 5 (2023); 15997-01eThe Journal of Engineering and Exact Sciences; Vol. 9 Núm. 5 (2023); 15997-01eThe Journal of Engineering and Exact Sciences; v. 9 n. 5 (2023); 15997-01e2527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/15997/8029Copyright (c) 2023 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCaetano, Ian Pellinca BragaStapelfeldt, Danielle Marques de AraújoMelo, Rodrigo de SiqueiraFreitas, Kênia da SilvaShiguihara, Ana LuciaAmim Júnior, Jorge2023-06-27T12:44:31Zoai:ojs.periodicos.ufv.br:article/15997Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2023-06-27T12:44:31The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
