Resumo
This work presents the preparation and characterization of a nanocomposite based on
Poly(butylene terephthalate) PBT and Brazilian smectitic clay (bentonite chocolate clay). Before
being incorporated as clay nanoparticles in PBT resin, the clay was organically modified by the
addition of a quaternary salt and sodium carbonate. PBT/Clay nanocomposite (96.3:3.70 wt %)
was obtained by using a twin-screw extruder machine. After extrusion process, the
nanocomposite was characterized by tensile, flexural and impact tests, SEM, Vicat, HDT, DSC,
TGA and XRD tests. The results showed that the properties of the nanocomposite obtained were
superior to those of neat PBT. Concerning the temperature of thermal distortion (HDT) an
expressive gain of around 45 % was presented to PBT/Clay nanocomposite compared to PBT
evidencing the interaction of nanofiller with the polymeric matrix.
