| titleOfInvention | Preparation method of thermoreversible color-changing composite material based on polydiacetylene and metal organic framework compound |
| abstract | The invention provides a preparation method of a thermoreversible color-changing composite material based on Polydiacetylene (PDA) and metal organic framework compounds (MOFs), namely, pure diacetylene monomer (DA) is dispersed into a dimethyl sulfoxide-deionized water mixed solvent; dispersing a metal organic framework compound in deionized water, and adding the metal organic framework compound into an acetylene monomer solution to form a mixed solution; then, performing ultrasonic treatment on the mixed solution at 65-80 ℃ for 30-60 min, and cooling the mixed solution at a low temperature for self-assembly to obtain a white suspension; and then irradiating the white suspension under ultraviolet light with the wavelength of 254 nm for polymerization to obtain blue suspension, namely the thermoreversible color-changing composite material. According to the invention, through the interaction between the PDA and the MOFs, disordered PDA conformations can be restored to ordered conformational arrangement after heating, so that the composite material is quickly restored to blue from purple red, therefore, the composite material has excellent thermo-reversible color change behavior, and can be applied to numerous fields as a temperature sensor. |
