Eco-design Building blocks and materials

and eco- functionalization: chemical and/or enzymatic
modifications (covalent and non-covalent
coupling, oxidation, polymerization), and/or
production physical treatments (ultrasound, micro-wave,
grinding, corona, or plasma) of the bio-based
of high-added- building blocks to obtain biosourced devices
with innovative properties (hydrophobic, anti-
microbial, bionano-electronic, etc.).
value functional Cotrolled self-assembly and nano-
organization: directed self-assembly of
bio-based biosourced building blocks, innovative
processes to obtain nano-structured materials

materials (nanoprecipitation, «spin or dip-coating»),
development of smart surfaces, three-dimentional
materials, as well as functionalized and multi-
compartmentalized glyco-nanoparticles.

biosourced materials: adapting or developing
techniques that foster industrial transfer,
Business lines understanding interactions at interfaces and

PolyNat research topics focus on four scientific and life cycle for their eco-designing and circular
technological challenges: economy.

Bio-based building blocks extraction from
plant biomass and their characterization:
molecules (oligosaccharides, aromatics),
biopolymers (hemicellulose, lignin, cellulose),
nanocellulose (nanocrystals, microfibrils,
nanofibrils), cellulose fibers.

PolyNat experts
offer tailor-
made research,
from the bench
to the industrial
pilot, to develop
alternatives to
petro-sourced
materials and
meet regulatory
constraints.
