Abstract: Abstract Accompanying with tremendous efforts devoted to prompting recycling and mitigating disposal problems pertinent to obsolete polymer materials, it is imperative to ameliorate thermoset polymer composites that are both mechanically robust and reprocessable. Herein, we… read more here.

Abstract: Abstract Endowing thermoset polymers with reinforcement, reprocessability and multi-functions shows great potential in practice. Herein, we describe the facile synthesis of robust, healable and reprocessable aminated silica/polydimethylsiloxane (PDMS) composites by engineering dynamic vinylogous urethane crosslinks… read more here.

Abstract: Abstract In this letter, we present a robust covalent adaptable network (CAN) that relies on dynamic, exchangeable thiourethanes. A primary aliphatic isocyanate, hexamethylene diisocyanate (HDI), and a primary aliphatic thiol, ethoxylated-trimethylolpropane tri(3-mercaptopropionate) (EETMP), are employed… read more here.

DOI: 10.1021/acsami.0c19520
Abstract: Reprocessable acrylate vitrimer needs to enhance its strength to expand the application in photo-three-dimensional (photo-3D) printing. However, the methods for improving mechanical properties by the addition of nanofillers or a multifunctional resin into acrylate vitrimers… read more here.
