Abstract Self-healing and recyclable polymer materials are being developed through extensive investigations on noncovalent bond interactions. However, they typically exhibit inferior mechanical properties. Therefore, the present study is aimed at synthesizing a polyurethane–urea elastomer with excellent properties shape-memory-assisted self-healing behavior. In particular, introduction of coordination hydrogen bonds into leads to optimal exhibiting good (strength, 76.37 MPa; elongation break, 839.10%; toughness, 308.63 MJ m −3 ) owing phased energy dissipation mechanism involving various supramolecular The also demonstrates shape-memory properties, whereby shape recovery force that brings damaged surfaces closer facilitates self-healing. Surprisingly, all specimens exhibite clustering-triggered emission, cyan fluorescence observed under ultraviolet light. strategy reported herein for developing multifunctional can be leveraged yield stimulus-responsive polymers smart seals.

Rosin-Modified Polyurethane Elastomers with Room-Temperature Self-Healing Ability, High Strength, and Recyclability Based on Oxime Dynamic Bonds

ACS Applied Polymer Materials, Год журнала: 2024, Номер 6(3), С. 1730 - 1739

Rosin, with a rigid hydrogenated phenanthrene ring, is widely available biomass, but its high-value utilization needs to be enhanced. Inspired by sustainable development strategies, the design of polymer elastomers room-temperature self-healing capability has been hot focus topic. However, designing that combine conflicting properties high mechanical performance and significant challenge. The ring rosin provides superior solution this problem. In work, polyurethane elastomer (BPU-X% AP) based on rosin-hydrogenated structure, dynamic oxime, hydrogen bonding was reported. BPU-X% AP exhibits tensile strength (37.8 MPa), good toughness (126.9 MJ m–3). Due structure promotes movement chain segments, have fast recyclability. Benefiting from their excellent properties, as adhesives strong lap shear 5.5 MPa, they can used melt binders. Corresponding cycling elastomer, adhesive BPU-10% remains almost same after three cycles adhesion iron aluminum plates. This work viable approach for preparation high-performance biomodified polyurethanes.
