“…Remarkably, the composites of clay minerals and cellulose acetate (CA) were found to possess the peculiar physical and chemical properties [28]. Nevertheless, the clay minerals were used as fillers for those composites and the quantity of clay minerals in them was usually less than 5 wt.% [29]. Therefore, those composites are not suitable to be used as adsorbents because of the lack of adsorptive properties [30].…”

“…Observa-se para o sistema PE/D-OMMT um ombro em torno de 4,7° (d 001 = 18,8 Å), correspondente, à parte da argila que não foi intercalada pelas cadeias do polímero, ficando em uma posição entre o ângulo da argila não modificada MMT 7,0° (d 001 = 12,5 Å) e da argila modificada D -OMMT 4,19° (d 001 = 20,7 Å), conforme trabalho já publicado [19] . Isso indica que houve uma redução do espaçamento basal da argila organofílica, provavelmente, devido ao cisalhamento insuficiente, durante a preparação e processamento dos materiais, para promover a dispersão da argila [21] . A tensão de cisalhamento contribui efetivamente para a difusão das cadeias poliméricas para dentro das galerias da argila, uma vez que a tensão de cisalhamento pode quebrar os aglomerados das partículas ou tactóides, aumentando o grau de intercalação/esfoliação sob condições de mistura.…”

“…A nanocomposite is new class of composites derived from the ultrafine inorganic particles with dimensions typically in the range of 1-1000 nm that are dispersed in the polymer matrix homogeneously [1]. In past decades, there were a variety of attempts to achieve polymer grafted nano-sized silica nanoccomposites [2,3]. Most recently, there is a rising trend to prepare the heterochain polymers/silica nanocomposites with chemical bonds between the polymers and the silica nanotubes.…”
