Autor: Renata Barbosa, Dayanne Diniz Souza Morais, Karine Castro Nóbrega, Edcleide Maria Araújo, Tomás Jeférson Alves Mélo

Publikováno v: Materials Research, Vol 15, Iss 3, Pp 477-482 (2012)

Nanocomposites were processed using the technique of melt intercalation, starting from a concentrated polar compatibilizer/organoclay (PE-g-MA/organoclay) prepared in an internal mixer. The concentrate was incorporated into the matrix of HDPE by two
