IMP-Days : New Challenges for THERMOSETS
avril 15 - avril 18
This second edition of IMP Days will be dedicated to thermosetting materials, both a scientific and industrial topic close to Jean-Pierre Pascault’s heart. Thermosetting polymers which are defined as highly-crosslinked chemical networks exhibit high thermal, chemical and mechanical stability. These properties make thermosets very suitable for structural and protective applications in various fields such as composite, coating and adhesives. Typical families of thermosetting polymers are phenolic and urea-formaldehyde resins, unsaturated polyesters, polyurethane and epoxy networks. Thermosets-related research stays particularly challenging since these materials are historically obtained from petroleum-based reactants and still generally suffer from brittleness and poor recycling ability. Choice of monomers should be rethought, involving blocks from renewable resources, managing material’s end of life for allowing its reprocessing and recycling, introducing dynamic bonds to improve processing and/or self-healing ability…
