Resumo: This study aimed to evaluate the properties of soda lignin obtained from an unconventional and abundant waste - the rambutan peel - since lignin has been shown as the most promising natural organic feedstock alternative to petroleum for polymer science. FTIR analysis and pH measurements have confirmed the acidic form of lignin, which has shown solubility in a wide range of polarities and so many solvents, making its insertion easy on polymeric matrices. While the ability to absorb UV-light was higher than commercial lignin tested as reference, the morphology and size distribution at microscopic level were less regular than that. When added to a starch-based film, the lignin decreases its natural affinity for water, improving the barrier properties, as well as increasing its thermal resistance. Microorganisms could be developed easily on starch-based films containing this kind of lignin. This material, still underreported for technological applications, points towards as promisor to be a component or additive in polymeric matrices.

Las medidas del pH y FTIR han confirmado el carácter ácido de esta lignina, soluble en distintos disolventes y polaridad, lo que facilita su adición a matrices poliméricas. Si bien la capacidad de absorción de luz ultravioleta fue mayor en comparación con la lignina comercial probada como referencia, la morfología y la distribución del tamaño fueron menos regulares. Cuando se agrega a una película de almidón, la lignina disminuye su afinidad natural por el agua, mejorando tanto sus propiedades de barrera como su resistencia térmica. Los microorganismos se desarrollan fácilmente en películas de este tipo que contienen lignina de rambután. Aunque los reportes de sus aplicaciones tecnológicas sean muy raros, esa lignina tiene potencial como componente o aditivo en matrices poliméricas.O objetivo deste trabalho foi avaliar as propriedades da lignina soda obtida a partir de um resíduo abundante e não convencional - a casca do rambutan - uma vez que a lignina tem se mostrado como a mais importante fonte de matéria orgânica alternativa ao petróleo para ser usada em ciência de polímeros. Análises de FTIR e medidas de pH confirmaram a natureza ácida dessa lignina, mostrando-se solúvel em solventes de polaridades variadas, o que facilita sua adição a matrizes poliméricas. Enquanto a capacidade de absorção de luz ultravioleta foi maior em comparação à lignina comercial testada como referência, a morfologia e distribuição de tamanho no nível microscópico foram menos regulares. Quando adicionada a um filme de amido, a lignina diminui sua afinidade natural por água, melhorando tanto suas propriedades de barreira quanto sua resistência térmica. Micro-organismos se desenvolveram facilmente em filmes desse tipo que continham a lignina de rambutan. Esse material ainda pouco explorado em aplicações tecnológicas apresenta potencial para ser usado como componente ou aditivo em matrizes poliméricas.Research, Society and Development2022-01-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2532010.33448/rsd-v11i1.25320Research, Society and Development; Vol. 11 No. 1; e49911125320Research, Society and Development; Vol. 11 Núm. 1; e49911125320Research, Society and Development; v. 11 n. 1; e499111253202525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/25320/22111Copyright (c) 2022 Emanoel Igor da Silva Oliveira; Jean Brito Santos; Silvana Mattedi; Nádia Mamede Joséhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessOliveira, Emanoel Igor da Silva Santos, Jean Brito Mattedi, SilvanaJosé, Nádia Mamede 2022-01-16T18:08:18Zoai:ojs.pkp.sfu.ca:article/25320Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:43:37.995673Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
