Outline of Final Research Achievements

Bis(hydroxymethyl)furan, which is easily produced from carbohydrates available from biomass, was polymerized with biobased di carboxylic acids to obtain polyesters, which were further crosslinked with bis-meleimides by thermally reversible Diels-Alder reaction. Mechanical property enhancement of the network polymers were conducted through the comparison of the ones crosslinked with five different bismaleimides and the ones obtained by copolymerization with other biobased monomers. We also analyzed the relationship between glass transition temperature and self-healing ability of the network polymers and developed an efficient way to produce relatively tough materials with high healing ability under mild conditions, such as at 50 degree C. Further, a very simple method to fabricate multishape memory films with flexible design capabilities from the network polymer was proposed.
