Preparo de nanocompósitos de poli(succinato de butileno) (PDS) e argila motmorilonita organofílica via polimerização in situ

Abstract: Resumo: Nanocompósitos de poli(succinato de butileno) (PBS) e argila montmorilonita organofílica foram sintetizados via polimerização in situ, em três diferentes concentrações (4, 6 e 8% em massa). Os produtos obtidos foram caracterizados por diversas técnicas. Entre elas, a difração de raios X foi útil para comprovar o aumento do espaçamento interlamelar da argila devido à incorporação das cadeias de polímero. As técnicas de análise térmica mostraram que o método de polimerização in situ gerou materiais com m… Show more

“…The occurrence of terminal vinyl groups is attributed to the degradation reaction of the PBS chain. 19,20 Composites, in comparison with pure PBS, do not present changes in their FTIR spectra simply because NaCl does not absorb in the IR region.…”

“…Among the biodegradable polymers, poly (butylene succinate), PBS, can be obtained from petrochemical sources or by a wholly renewable route from chemical intermediates produced in the carbohydrates fermentation such as sucrose, glucose, maltose, and fructose . PBS has excellent processability, biodegradability, low production value and its microbiological degradation generates final products such as CO 2 and H 2 O …”

“…[52] Among them, poly (butylene succinate), PBS, is an aliphatic polyester, being a white crystalline thermoplastic, with a melting point in the range of 90°C to 120°C. PBS has gained prominence, [7,10,33,[53][54][55][56][57][58][59][60][61][62] as a renewable and biodegradable alternative to polymers from petrochemical sources. Besides, PBS is handy in biomedical and pharmaceutical applications.…”
