Renewable and recyclable covalent adaptable networks based on bio-derived lipoic acid

Abstract

The modern materials economy is inefficient since most products are principally derived from non-renewable feedstocks and largely single-use in nature. Conventional thermoset materials are often inherently unreprocessable due to their...

Sustainable design of vanillin-based vitrimers using vinylogous urethane chemistry

“…Vitrimers, introduced by the pioneering work of Leibler et al, 9 are thermally triggered associative CANs that experience an Arrhenius-like viscosity decrease, rather than a sudden viscosity decrease, as seen for dissociative CANs upon a thermal trigger. 10 Among bio-based CANs, many types of renewable building blocks, ranging from terpenes to oils, 11,12 fatty acids, 13 fructose, 14 lipoic acid, 15 ferulic acid, 16 or vanillin, [17][18][19][20] have been incorporated into dynamic materials. Very recently, the field of bio-based CANmaterials has been reviewed.…”

Lithium Bonds Enable Small Biomass Molecule‐Based Ionoelastomers with Multiple Functions for Soft Intelligent Electronics

“…Therefore, the use of renewable chemicals originating from biomass resources as polymer substrates is an attractive option for the next generation of IE materials, because it is beneficial to reducing the fabrication cost and improving the overall sustainability. [ 8 ] Yet, the existing molecular designs and engineering make it difficult or even impossible to integrate biomass resources, liquid‐free, easy fabrication, eco‐friendly, and multi‐functions into IE materials simultaneously. Furthermore, the non‐recyclability and non‐degradability of existing IEs means that most of them will eventually be turned into electronic waste (e‐waste).…”

Biobased covalent adaptable networks: towards better sustainability of thermosets

“…17). 189 The CAN was synthesized from a commercial tri-armed thiol and a dimerized lipoic acid monomer containing a dynamic cyclic disulfide moiety. The dimerized lipoic acid monomer was obtained via a coupling reaction between EDC and the carboxylic acid group on lipoic acid.…”
