Efecto de la adición de bentonita sobre las propiedades ópticas de diferentes materiales compuestos poliméricos

ABSTRACT In this work, composite materials were obtained by the incorporation of bentonite to biodegradable and synthetic polymeric matrices. Commercial (BE) and natural (BM) bentonite samples were employed, as well as three different polymeric matrices: thermoplastic corn starch (TPS), high density polyethylene (HDPE) and a poly(styrene-b-butadiene-b-styrene) triblock copolymer (SBS). Composite materials were obtained by incorporating 5 % w/w filler by melt mixing. Films were obtained by thermo-compression in a hydraulic press. By Scanning Electron Microscopy (SEM) it were examined the homoge...
