The invention discloses bacterial cellulose-silicon dioxide P-COF aerogel and a preparation method and application thereof. The product is prepared by a three-step method of sol-gel transformation, solvent exchange, and drying. Bacterial cellulose is used as the matrix, and the mechanical properties of the composite aerogel are significantly enhanced by secondary molding. Phosphorus (P), as a flame retardant element, can play a role in the gas phase or condensed phase to improve the fire resistance of the polymer. It can be loaded on COF to obtain P-COF, which has a flame retardant effect. Through the cross-linking of COF materials The effect improves the mechanical strength and stability of the product, and has excellent thermal insulation properties. In addition to cross-linking and support, COF materials have a porous structure that can play an adsorption role, so it can improve the removal rate of toxic substances or pollutants. |
