The preparation and reprocessing of an epoxy vitrimer material is performed in a fully biocatalyzed process wherein network formation exchange reactions are promoted by lipase enzyme. Binary phase diagrams introduced to select suitable diacid/diepoxide monomer compositions overcoming the limitations (phase separation/sedimentation) imposed curing temperature inferior than 100 °C, protect ability TL, embedded chemical network, catalyze efficiently (transesterification) demonstrated combining...
Hybrid networks, including physical and chemical cross-links, were synthesized from biosourced fatty acid fragments, linked to each other by a controlled number of nonexchangeable ether bonds, exchangeable ester noncovalent hydrogen bonds. The mechanical properties these networks are tuned the ratio di- versus tetraepoxide stoichiometry acid/epoxy. Creep tests insolubility demonstrated vitrimer or vitrimer-like nature resulting materials. thermostimulated welding ability materials was...
Commercially available lipase from Pseudomonas stutzeri (lipase TL) is investigated as a biocatalyst for the formation of an acid-epoxy chemical network. Molecular model reactions are performed by reacting 2-phenyl glycidyl ether and hexanoic acid in bulk, varying two parameters: temperature water content. Characterizations formed products 1H NMR spectroscopy gas chromatography-mass spectrometry combined with enzymatic assays confirm that TL able to simultaneously promote addition...
Soft robotics is an emergent branch of robotics, which involves incorporation elastomeric elements.Addition soft materials into robotic devices allows better flexibility and adaptability to the environment than when robots are made hard rigid components.However, more prone damage their counterparts.Incorporation self-healing may permit fix damages.Equipped with a sensor, robot could also be able detect initiate repairing process autonomously.In this work, fibre strain sensors were integrated...
