Resumo: The production of ecological materials is being encouraged, aiming to minimize environmental impacts and promote greater sustainability. Therefore, this work aimed to develop bio-polyethylene biocomposites (BioPE)/wood flour (WF), using polyethylene grafted with maleic anhydride (PE-g-MA) as a compatibilizer. The biocomposites were prepared in a corrotational twin screw extruder and injection molded. The properties of Izod impact strength, tensile strength, Shore D hardness, Heat Deflection Temperature (HDT) and water absorption were investigated. Impact strength improved when biocomposite BioPE/WF was made compatible with PE-g-MA. This increase was more expressive for 10% of PE-g-MA with a high degree of maleic anhydride grafting, indicating a higher level of interaction between the phases. The BioPE/WF/PE-g-MA biocomposites showed improved elastic modulus, tensile strength, Shore D and HDT hardness, compared to the non-compatible biocomposite. An important aspect was the reduction of water absorption for biocomposites compatible with PE-g-MA, suggesting a greater barrier effect for the diffusion of moisture. From the point of view of the degree of grafting of maleic anhydride in PE-g-MA, in general, impact strength was the most sensitive property. The results indicate that wood flour is a waste with the potential to be reused in the development of biocomposites.

Por lo tanto, este trabajo tuvo como objetivo desarrollar biocompuestos de biopolietileno (BioPE)/harina de madera (HM), utilizando polietileno injertado con anhídrido maleico (PE-g-MA) como compatibilizador. Los biocomposites se prepararon en una extrusora de doble husillo rotacional y se moldearon por inyección. Se investigaron las propiedades de resistencia al impacto Izod, resistencia a la tracción, dureza Shore D, temperatura de deflexión térmica (HDT) y absorción de agua. La resistencia al impacto aumentó cuando el biocompuesto BioPE/HM se hizo compatible con PE-g-MA. Este aumento fue más expresivo para el 10% de PE-g-MA con un alto grado de injerto de anhídrido maleico, lo que indica un mayor nivel de interacción entre las fases. Los biocompuestos BioPE/HM/PE-g-MA mostraron propiedades mejoradas de módulo elástico, resistencia a la tracción, dureza Shore D y HDT, en comparación con el biocompuesto no compatible. Un aspecto importante fue la reducción de la absorción de agua para biocomposites compatibles con PE-g-MA, sugiriendo un mayor efecto barrera para la difusión de la humedad. Desde el punto de vista del grado de injerto de anhídrido maleico en PE-g-MA, en general, la resistencia al impacto fue la propiedad más sensible. Los resultados indican que la harina de madera es un residuo con potencial de reutilización en el desarrollo de biocomposites.A produção de materiais ecológicos está sendo incentivada, visando minimizar os impactos ambientais e promover uma maior sustentabilidade. Portanto, esse trabalho, teve como objetivo desenvolver biocompósitos de biopolietileno (BioPE)/farinha de madeira (FM), utilizando como compatibilizante o polietileno enxertado com anidrido maleico (PE-g-MA). Os biocompósitos foram preparados em uma extrusora de rosca dupla corrotacional e moldados por injeção. As propriedades de resistência ao impacto Izod, resistência à tração, Dureza Shore D, Temperatura de Deflexão Térmica (HDT) e absorção de água foram investigadas. A resistência ao impacto aumentou quando o biocompósito BioPE/FM foi compatibilizado com PE-g-MA. Esse acréscimo foi mais expressivo para 10% de PE-g-MA com alto grau de enxertia de anidrido maleico, indicando um maior nível de interação entre as fases. Os biocompósitos BioPE/FM/PE-g-MA apresentaram propriedades de módulo elástico, resistência à tração, dureza Shore D e HDT aprimoradas, em comparação ao biocompósito não compatibilizado. Um aspecto importante foi a redução da absorção de água para os biocompósitos compatibilizados com PE-g-MA, sugerindo um maior efeito barreira para a difusão de umidade. Do ponto de vista do grau de enxertia de anidrido maleico no PE-g-MA, em geral, a resistência ao impacto foi a propriedade mais sensível. Os resultados indicam que a farinha de madeira é um resíduo com potencial para ser reaproveitado no desenvolvimento de biocompósitos.Research, Society and Development2021-06-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1627710.33448/rsd-v10i7.16277Research, Society and Development; Vol. 10 No. 7; e23310716277Research, Society and Development; Vol. 10 Núm. 7; e23310716277Research, Society and Development; v. 10 n. 7; e233107162772525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/16277/14737Copyright (c) 2021 Fabiano Santana da Silva; Wallisson Alves da Silva; Carlos Bruno Barreto Luna; Eduardo da Silva Barbosa Ferreira ; Edcleide Maria Araújohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Fabiano Santana da Silva, Wallisson Alves da Luna, Carlos Bruno Barreto Ferreira , Eduardo da Silva Barbosa Araújo, Edcleide Maria 2021-07-18T21:07:03Zoai:ojs.pkp.sfu.ca:article/16277Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:52.414669Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
