Abstract

The collagen hydrolysate (HC) and silver nanoparticles (AgNPs) effect on the mechanical, thermal, in vitro degradation, cytotoxicity and antifungal properties of polylactic acid (PLA) plasticized and compatibilized with a mixture of polyethylene glycol (PEG 4000) and Lapol 108 (MB) was studied. The presence of HC led to the decreased tensile properties and to the increased hydrophilicity of biocomposites surfaces. Tested biocomposites led to a very good cellular viability percentage, unaltered cell morphology and a modest antifungal activity. The extrusion trial showed that the PLA/MB/PEG/AgNPs bionanocomposite is a promising potential material for urinary drains.
