High-Strength and Self-Healing Polyurethane Based on Dynamic Covalent Bonds for Concrete Protection
To extend the service life of concrete in harsh environments, this paper introduces a silicone-modified polyurethane with self-repairing capabilities. The integration of silicone and disulfide bonding into the polyurethane molecular chain endows the material with a self-repairing ability and hydrophobicity. The incorporation of silicone significantly enhances the polyurethane’s hydrophobicity, while the introduction of disulfide bonds enables damage repair under mild conditions, and the repair efficiency can reach 90%. This combination of hydrophobicity and self-repairing properties holds paramount importance in protecting concrete and ensuring its prolonged use.
期刊介绍：
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
