Biobased polymers

Aude Cordin is both lec­tur­er at UTC and lec­tur­er-cum-research sci­en­tist the Enzy­mat­ic and Cel­lu­lar Engi­neer­ing (UTC-GEC) lab­o­ra­to­ry. Her research field lies at the inter­face between biore­sources, bio­mimet­ics and polymers.

One of her main areas of research? “I’m look­ing to design biodegrad­able encap­su­la­tion sys­tems that respond to changes in their envi­ron­ment using mol­e­c­u­lar­ly imprint­ed poly­mers (MIPs). While these poly­mers are usu­al­ly petro-sourced, my work involves devel­op­ing this type of mate­r­i­al using bio-sourced monomers or poly­mers and man­u­fac­tur­ing meth­ods that are much “gen­tler” and more com­pat­i­ble with the envi­ron­ment”, explains Aude Cordin.

This is an issue of inter­est, since Aude Cordin has been cho­sen to coor­di­nate the Eco­Bio­Plast project fund­ed by the French agency, ANR. Launched in Octo­ber 2022 for a four-year peri­od, Eco­Bio­Plast is being con­duct­ed in part­ner­ship with Antoine Fayeulle from UTC-TIMR.

What is the aim of the project? “The aim is pri­mar­i­ly to under­stand the envi­ron­men­tal fate of micro- and nanoplas­tics in order to devel­op new, more eco-com­pat­i­ble encap­su­la­tion sys­tems for the release of biopes­ti­cides, set to replace syn­thet­ic pes­ti­cides. To date, these biopes­ti­cides are not very sta­ble. They can also have sol­u­bil­i­sa­tion prob­lems when it comes to for­mu­la­tions. Hence the objec­tive of encap­su­lat­ing them to facil­i­tate their use, but the matrix must be com­pat­i­ble with the envi­ron­ment, such as poly­sac­cha­rides from algae, fun­gi or veg­etable oil deriv­a­tives, for exam­ple”, she explains.

This project fol­lows on from the suc­cess­ful pro­duc­tion of mol­e­c­u­lar­ly imprint­ed poly­mers from veg­etable oil deriv­a­tives. “The aim was to encap­su­late polyphe­nols, antiox­i­dant mol­e­cules. In this par­tic­u­lar case, we suc­ceed­ed in show­ing that this type of matrix was sen­si­tive to enzymes and was there­fore degrad­ed in their pres­ence, allow­ing the active ingre­di­ent to be released”, con­cludes Aude Cordin.
