Abstract: A film (1) includes hollow particles (10) and a binder (20). The hollow particles are made of a material having a refractive index of 1.15 to 2.70. The binder (20) is formed of at least a polysilsesquioxane and binds the hollow particles (10). The film (1) satisfies at least one of requirements Ib/Ia≥0.7 and Ib/Ic≥0.3. Ia is an absorbance derived from a hydrocarbon group not directly bonded to a silicon atom, the absorbance being determined by attenuated total reflection using a Fourier transform infrared spectrophotometer. Ib is an absorbance derived from a bond between a silicon atom and a non-reactive functional group. Ic is an absorbance derived from a bond between a silicon atom and a hydroxy group.

Abstract: An environmentally-friendly flexible conductive polyurethane (PU) and a preparation method thereof are disclosed. The environmentally-friendly flexible conductive PU is prepared by subjecting a mixture of a component A and a component B in a specified mass ratio to in-situ solvent-free polymerization, where the component A is prepared from a polyol, a T-type chain extender, a diselenide diol, high-conductivity carbon black, a dispersing agent, a catalyst, and a leveling agent, and the component B is prepared from a polyisocyanate, a polyol, a multi-walled carbon nanotube (MWCNT), and a dispersing agent. The PU has a reliable electrically-conductive function, and shows a self-healing function under room temperature or light conditions when damaged, wherein a microphase separation value HBI (0.5 to 3.0) of soft and hard segment molecules can be adjusted to achieve different hand touches and different mechanical properties, and an organic pollutant emission (volatile organic compound (VOC)) is less than 50 mg/kg.
