Abstract
In this study, a novel simple and fast method was developed of immobilizing a natural polysaccharide (chitosan) on a polylactide (PLA) surface. In order to overcome the lack of surface adhesion between the chitosan and the PLA due to incompatibility issues, atmospheric pressure plasma was used. The plasma activation was able to modify the PLA surface by generating surface chemistry proper for stabilizing the chitosan layer. The activation of the surface was monitored through water contact angle (WCA) measurements and X-ray photoelectron spectroscopy (XPS). Indeed, the introduction of new

To create natural, biobased or reborn, reactive, functional, biocompatible and biodegradable polymers, surfactants and hydrogels applicable in medicine, pharmacy, cosmetics or agrifood and meeting the need of Present without compromising the need of Future.
Our research thereby covers over ten-years experience in the following area:
- Transforming (natural) by-products as sustainable plastic materials and proposing adapted end-of-life plastics,
- Adapting energy-efficient methods towards their transformation (reactive extrusion, mechanochemistry, enzymatic catalysis),
- Ecodesigning and upcycling these materials into applications such as biomedical, food, etc.;
