In this study, we synthesized new biomass-derived cellulose acetate (CA) derivatives by ring-opening graft polymerization of δ-valerolactone followed by the introduction of ureidopyrimidinone (Upy) groups in the polymer side chains. Due to the semicrystalline aliphatic characteristics of the side chain poly(δ-valerolactone) (PVL) and quadruple hydrogen bonds formed by the Upy groups, the stretchability of the resulting polymers was significantly enhanced. Moreover, the shape memory ability and self-healing property (58.3% of self-healing efficiency) were successfully imparted to the polymer. This study demonstrates the great significance of using biomass sources to create self-healing polymers.Science and technology of advanced materials2320082https://www.ebi.ac.uk/biostudies/studies/S-EPMC10919307biostudies-literatureSelf-healing and shape-memory polymers based on cellulose acetate matrix.PMC10919307Yokochi HMichinobu TJia HOtsuka HJimbo KfalseSelf-healing and shape-memory polymers based on cellulose acetate matrix.The creation of self-healing polymers with superior strength and stretchability from biodegradable materials is attracting increasing attention.
