The influence of natural clay and organoclay vermiculite on the formation process of bionanocomposites with poly (3-hydroxybutyrate-co-3-hydroxyvalerate)

Abstract: During the last decades, a lot of research work focused on several biodegradable and biosourced polyesters for the purpose of reducing the non-degradable polymer wastes. These polyesters are particularly considered to be promising polymers for biomedical applications and short lifetime products like packaging. As these packagings are rapidly discarded, especially the food ones, their accumulation becomes a serious environmental problem. In order to replace these materials with new ones that do not harm the env… Show more

“…Hence, it is possible to use it as an excellent insulator with high thermal stability. In addition, the possibility of exfoliation makes it a filler that can be used to create various composite and nanocomposite materials with novel functionalities [30,31].…”

“…They are also effective in terms of food packaging applications and shows inertness as well in terms of interaction with food. So, these properties make them vermiculite important material [30]. Oliveira et al, (2015) studied the polyester-starch matrix-based vermiculite biodegradable nanocomposites by the melt intercalation method by using injection molding as a processing technique.…”

“…Neste contexto, o trabalho teve como objetivo preparar via extrusão plana filmes de biocompósitos com matriz de PE Verde e carga de VMT no teor de 1%. O teor de VMT foi baseado em trabalhos publicados pelo grupo de pesquisa, sendo amplamente discutido por SILVA JÚNIOR et al [14] e REIS et al [15]. Posteriormente, os filmes receberam tratamento nas suas superfícies por meio de plasma sob duas condições distintas: sob atmosfera de oxigênio (O2) (Condição 1 -C1); e um pré-tratamento com a mistura de atmosferas de argônio/hidrogênio (Ar/H2) e o posterior tratamento por plasma sob atmosfera de O2 (Condição 2 -C2).…”
