dc.description.abstract | Combined effects of clay treatment and
compatibilizer polymers on the structure and properties of
polypropylene/clay nanocomposites were studied. Dynamic
mechanical analysis was used to analyze comparatively
the dynamic mechanical response of different nanocomposites
prepared from polypropylene and montmorilloniterich
bentonite, and to relate such response with the material
microstructure. Two different bentonites were used: a
purified Spanish natural bentonite was organophillized by
means of 11-undecyl-ammonium ion and a commercial
bentonite organophillized with dimethyl dehydrogenated
tallow ammonium ion. Three different polar copolymers
were employed as compatibilizer agents in some of the
formulations: maleic anhydride-grafted polypropylene,
maleic anhydride-grafted poly(styrene-co-ethylenebutyleneco-
styrene), and poly(ethylene terephthalate-co-isophthalate)
(PET). To ascertain the microstructure characteristics
in the nanocomposites, wide angle X-ray diffraction, transmission
electron microscopy, and differential scanning
calorimetry techniques were used. The nanocomposites containing
both bentonite organophillized with 11-undecylammonium
ion and PET, and maleated PP as compatibilizer
system, were found to have the highest storage modulus
and the smallest loss factor values, which was mainly due
to the better clay platelets dispersion. The dynamic mechanical
response of nanocomposites prepared with bentonite
organophillized with dimethyl dehydrogenated tallow
ammonium ion and maleated SEBS was strongly affected
by the presence of this compatibilizer. The temperature of
PP and a, b, and g relaxations strongly depended on the
interactions between the different phases in the nanocomposites. |
