Biodégradation des polymères en milieu marin
Pollution of the ocean by plastic litter has become a major environmental problem in recent years. One of the reasons of the increasing pollution by conventional plastics is their extreme durability, initially considered as an advantage, but which leads to their undesirable accumulation in terrestrial and marine environments, whether as such or in the form of micro-plastics. This environmental concern thrives with an increasing demand from consumers for non-conventional plastics. Bio-sourced plastics is one of the major direction undertaken to produce more eco-friendly plastics, while keeping their use properties unchanged, but this alternative has not proven satisfactory yet. Moreover, even though the main degradation mechanisms have been identified (UV, waves, enzymes, bacteria), the degree to which “biodegradable” plastics actually biodegrade in the marine environment is still under debate.
Our research has two major axis :
-to deliver a comprehensive understanding of degradation mechanisms of polymers in marine environment in relation to their structure at different scales in order to lay down the basis for a generic model for the fate of plastics in the ocean (fragmentation versus biodegradation)
-to draw new directions towards the design of innovative eco-friendly polymers
In order to study degradation at the local scale of bacteria, we use atomic force microscopy (AFM) and measure both topographical and mechanical changes induced by the presence of the different degrading factors.
New concepts for eco-friendly materials are based on the synthesis of original block-copolymers.
