Polyurethane (PU) is a versatile material that can be customized to meet specific commercial requirements in different industries because of its favorable mechanical properties. However, it is not resistant to high temperatures, and it requires structural modifications before it can be used in high‐temperature structural materials. In this study, isocyanates and anhydrides are copolymerized at high temperatures to obtain a solvent‐free oligomer, thus eliminating the risks associated with highly polar aprotic solvents. A casting technique is used to synthesize a solid poly(urethane‐imide) (PUI) elastomer. According to the results, casting PUI (CPUI) exhibits optimal physical properties at a hard segment content of 30.5%. Incorporating an ether, symmetric, or imide structure into CPUI may reduce its hysteresis and improve its thermal creep performance. Compared with PU, CPUI exhibits considerably higher creep aging resistance. In dynamic load application tests, CPUI wheels take a substantially longer time to reach failure compared with PU wheels. Overall, CPUI is an environmentally friendly material with high elasticity, low creep, and high heat aging resistance and is suitable for static and dynamic manufacturing applications.

The comfort of polyester (polyethylene terephthalate or PET)as well as its reusability is greatly affected by its hydrophobicity. To improve the hydrophilicity of PET, titanium dioxide (TiO2) and gelatin were proposed to treat polyester by surface coating in this study. TiO2 and gelatin were selected because of their excellent ecological performance and wide usage. PET fabric had a super-hydrophilic surface and satisfied mechanical properties after various modifications. The synchronous treatment produced a significant effect. The fabric was coated with a dispersion of 4 g/l TiO2 and 5 g/l gelatin by the two-dip and two-rolling process. The static water contact angle of TiO2/gelatin-coated PET fabric reached 0° within 45 s. The results indicated that the PET fabric coated with TiO2/gelatin exhibited remarkable super-hydrophilicity and excellent resistance to wear and washing. Furthermore, the altered fabric underwent evaluation to assess its tensile fracture properties, air permeability, and crease recovery, which influenced its wearability and comfort. These performances demonstrate the potential application of TiO2/gelatin-coated PET fabric in textiles and apparel.
