Title

Smart gels of sequence-controlled polymers in organic solvents

Abstract

Sequence control is an emerging discipline of polymer science. In this movement, the objective of our researches is to implement novel functions in polymer materials through the control of sequence in copolymers. We previously reported physical gelation behavior of alternating copolymers consisting of monomers with long alkyl chain and phenol side groups in aromatic solvents; the SANS study performed at ILL revealed the presence of wormlike micellar objects. Since then, we observed by rheology the possibility of tuning the properties of these organogels, by controlled addition of small molecules. The current proposal aims to analyse the associated structural changes.
