Bio-based cyclic carbonates
WebI am an Assistant Professor at LCPO in Bordeaux University / CNRS / Bordeaux INP. My work is dedicated to the synthesis of new bio-based polymers and the analysis of their properties. My fields of expertise are: green chemistry, high-pressure chemistry, catalysis, step-growth polymerization, polyurethanes. WebSep 20, 2024 · In this work, a sustainable bio-based solid-state electrolyte was developed based on carbonated soybean oil (CSBO), obtained by organocatalyzed coupling of CO 2 to epoxidized soybean oil. CSBO coupled with lithium bis (trifluoromethanesulfonyl)imide salt on a bio-based cellulose separator resulted in free-standing membranes.
