Resumo
In this study, the effect of the organic (poly(lactic acid)) and the
inorganic (calcium carbonate (CaCOR3R)) fillers were evaluated in
mechanical, thermal, morphological and surface properties of the
poly(butylene adipate-co-terephthalate) (PBAT) matrix.
Mechanical results showed that the fillers has an influence on the
PBAT matrix. The use of CaCOR3R showed higher elongation at
break than PLA. However, the blends showed higher elastic
modulus, resulting in greater stiffness to the PBAT matrix. Both
fillers thermally destabilized the matrix. The morphological
properties showed a uniform dispersion of the fillers in the
composites and blends, however it is weaker with PLA. Because
the PBAT matrix surface is, intrinsically, hydrophobic, the
composites presented a smaller degree of hydrophobicity, while
the PLA makes the blends hydrophilic.
