Bacteriostatic polymer surfaces

Contact: CARROT Géraldine, , geraldine.carrot@cea.fr, +33 1 69 08 41 47
M1 or M2 level internship:
This project consists in the synthesis and the surface grafting of bacteriostatic polymers. The objective is to incorporate these polymers as a layer or a copolymer inside polyethylene films (main materials of food films). In addition to chemistry, both polymers and surfaces will be characterized by several analytical techniques (NMR, FTIR, XPS, microscopy, contact angles ...) before being studied in microbiology. This project will be performed at CEA ( Laboratory LICSEN/NIMBE) for the synthesis and surface chemistry part, in collaboration with INRA-AgroParisTech (Laboratory B2HM) for the characterization and microbiological tests. This project has an industrial support and may continue with a PhD thesis.

Possibility of continuation in PhD: Oui
Deadline for application:01/10/2022

Full description:
Microbial infections are a major concern for many commercial applications such as textiles, food packaging, water purification or medical equipment. The strategy we have chosen is based on the use of bacteriostatic polymers that we seek to incorporate into materials either via chemical grafting, deposits (printing) or mixing by extrusion. The objective of this course is therefore to form polymers or block copolymers in order to facilitate this incorporation. The compounds will then be intended to be mixed with the polymer matrix in order to form composite films (extrusion). After the characterization of polymers (size exclusion chromatography, NMR), particles (TGA) and surfaces (FTIR, XPS, goniometer), microbiological studies will be conducted with our partner team AgroParisTech.

We are looking for this internship, a motivated M2 student who has a solid background in chemistry and polymer characterization and knowledge in surface science (characterization).
Technics/methods used during the internship:
Polymer chemistry, FTIR, size-exclusion chromatography, contact angle, microscopy, profilometry, XPS
