Here, a novel strategy was developed to synthesize room-temperature intrinsic self-healing CED coatings by inserting 2-aminophenyl disulfide (APDS) into the polymer chain of cationic waterborne polyurethane (CWPU). Emulsion films incorporating the disulfide (SCWPU) could self-heal at room temperature via dynamic disulfide bond exchange and hydrogen bonding interactions, and their structures were confirmed by FTIR and Raman spectroscopy. The thermal properties of the SCWPU films were determined by differential scanning calorimetry and thermal gravimetric analysis. The effects of APDS incorporation and hard segment content (HSC) on the self-healing ability, mechanical and emulsion properties of the SCWPU films were systematically investigated. The results showed that the self-healing abilities of SCWPU film were 97.2% at RT over 24 h and 96.5% at 37°C (body temperature) after 4 h.

Fourier transform infrared spectroscopy (FTIR), optical microscopy analysis, and scanning electron microscopy (SEM) images, were first carried out to characterize the chemical composition and the morphology of the treated and untreated cotton fabrics, respectively. The investigation of flame resistance was evaluated by the vertical burning test. It was observed that the treated cotton fabrics exhibited good flame-retardant properties and did not burn even after 10 s flame application duration and the rate of flame spread was inhibited compared to the pristine cotton fabric. Furthermore, the thermal comportment of cotton fabrics was analyzed by thermogravimetric (TG) analysis and differential scanning calorimeter (DSC).
