Abstract

Processo de preparação, recobrimento e funcionalização de argilominerais e seu uso para a produção de nanocompositos poliméricos e produtos resultantes. Processo para a preparação de argilominerais revestidos e de seus respectivos compόsitos com polímeros polares e apolares. O invento esta baseado na secagem em condições apropriadas de uma suspensão coloidal da argila na presenca de um ou mais polímeros polares e solύveis no solvente empregado. O processo de secagem consiste na atomização para gerar uma nuvem de gotículas do material composto das nanoparticulas e dos polímeros de revestimento e remoção do solvente por evaporação. O material assim obtido, composto de nanoparticulas revestidas, pode ser facilmente disperso em matrizes polares e também apolares como polietileno e outras.
