Abstract
In order to design new antimicrobial nanocomposites with properties for food packaging application, films of polypropylene random copolymer (PPR), PPR/Poly-β-pinene (PβP), PPR/clay and PPR/PβP/clay were prepared by melt extrusion. Structural, morphological, mechanical, barrier, antimicrobial properties and thermal stability of the films were determined. PPR and PβP always form a homogeneous system in the amorphous phase; in the binary PPR/clay system, PPR molecules intercalate the clay galleries; in the ternary PPR/PβP/clay system, the miscibility between PPR and PβP prevents the intercalation of the PPR macromolecules into the clay galleries. The addition of clay and PβP increased the thermal stability and the tensile mechanical properties of PPR and reduced the oxygen transmission rate and the water vapor transmission rate compared with plain PPR. Films of nanomaterials containing PβP provided a reduction of the test microorganisms (Escherichia coli 25922) of 24% comparing to the control (PPR/clay film).
