Abstract
Innovative bioplastics blends and composites can be realized by extrusion. Interestingly poly(Lactic acid) (PLA) toughness can be improved by following two different strategies: the use of elastomeric additives such as poly(butylene adipate-co-terephtahale) (PBAT) or the use of rigid fillers, such as calcium carbonate. In both cases the combination with plasticization can be synergistic. The modulation of mechanical properties thanks to the knowledge of structure-properties relationships opened the possibility of exploiting these materials in a wide range of applications: packaging, automotive, personal care, cosmetics and biomedical devices. The preparation and selection of biobased materials compatible with skin in the framework of European H2020 POLYBIOSKIN project is essential for producing innovative healthy and highly ecofriendly products for the personal care sector. Functional treatments can be applied to make bioplastics suitable for specific goals (anti-microbial, anti-oxidant, anti-inflammatory, etc.). Testing the compatibility of the developed materials with cells is fundamental to evidence their potential compatibility with human body and eventual anti-microbial activity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
