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.313-318openAccesscalcium carbonatesbuteneslactic acidcomposite materialsorganic polymersEvaluation of the Poly (Lactic Acid) and calcium carbonate effects on the mechanical and morphological properties in PBAT blends and compositesArtigo de periódico64https://orcid.org/0000-0003-3546-1643Sem Percentil
