From vineyards to reshapable materials: α-CF₂ activation in 100% resveratrol-based catalyst-free vitrimers

Abstract

Vitrimers are a class of polymers bridging the gap between resistant crosslinked thermosets and recyclable linear thermoplastics. The first vitrimer ever described was a polyester network requiring relatively high catalyst...

Preparation of fluorinated polyesters by reversible addition–fragmentation chain transfer step-growth polymerization

“…2,3 Consequently, fluorinated polyesters have shown great potential in textiles, antifouling coatings, optical waveguide devices, biomedical devices, etc. 2,[4][5][6][7][8][9][10][11][12][13][14][15] Nevertheless, studies on fluorinated polyesters were few compared to other fluoropolymers, because of the difficulty in synthesis. 3 Polycondensation is the most common strategy to prepare fluorinated polyesters.…”

Preparation and Properties of Polysaccharide‐Based Epoxy Vitrimers

“…[1,2] The curing agents are of great importance to the properties of the cured epoxy resins. Common curing agents include amines, [3][4][5] acid anhydrides, [6][7][8][9][10] polyphenols, [11][12][13] polythiols, [14][15][16][17] and other modified curing agents. [18] Although there are currently various kinds of curing agents on the market, which can make the cured epoxy resin meet various market demands.…”

“…According to current reports, bio-based curing agents are mainly prepared from vanillin, [11,13] lignin, [30,33] etc. Few studies, however, have been done on synthesizing curing agents based on cellulose.…”

Chemically recyclable and mechanically robust non-isocyanate polyurethanes from resveratrol

“…Accordingly, use of the dynamic network can avoid drawbacks such as catalyst compatibility and premature aging of the vitrimers after several recycling/reshaping cycles. 11 The relatively low activity of transcarbamoylation and the high-temperature remolding process will result in certain damage to NIPU networks, such as oxidation and degradation. 8 Therefore, the remolding numbers of the NIPU networks are limited, and each cycle will diminish the properties of NIPUs.…”
