| Abstract | Obtaining sustainable low-temperature self-repairing polyurethane (PU) materials with outstanding mechanical performance is difficult and of pivotal importance to the corrosion protection of metals. Herein, we utilize the bio-based 2,5-Tetrahydrofurandimethanol (THFDM) chain extender and eco-friendly polydopamine-modified hydroxyapatite (PDA@HAp) nanosheets to fabricate sustainable body-temperature PU nanocomposite. The nanocomposite has an ultra-high tensile strength (36.84 MPa), outstanding toughness (211.8 MJ m-3), and good self-healing ability (81.97 %, 35 degrees C for 24 h; 94.46 %, 80 degrees C for 15 min) thanks to own optimal hydrogen bonding interactions. What's more, the composite coating after 30 days of soaking in 3.5 wt% NaCl solution also exhibits an impedance value (Zf=0.01 Hz) of 2.80 x 108 & omega; cm2 profiting from the barrier capability of PDA@HAp nanosheets. Hence, this work presents an effective way in which researchers can create a sustainable self-repairing PU nanocomposite with outstanding mechanical performance and corrosion resistance. |
