Abstract

The invention provides a glass fiber mat-nano TiO2 photocatalyst coating structure, which includes a glass fiber mat matrix and a nano TiO2 coating loaded on the surface of the glass fiber mat matrix. The nano TiO2 coating includes an average thickness of 10 to 50 nm. The particle size of nano-TiO2 particles is 5 to 30% by weight based on the weight of the glass fiber mat matrix. A method for preparing a glass fiber mat-nano TiO2 photocatalyst coating structure is also provided, in which a linear titanium polymer solution is used to coat a glass fiber mat matrix, dried and sintered to obtain a glass fiber mat-nano TiO2 photocatalyst coating structure. The glass fiber mat-nano TiO2 photocatalyst coating structure prepared from this linear titanium oxide polymer has excellent photocatalytic effect and super hydrophilic effect, and can be used for a long time, and can be applied to deodorizing filters, antibacterial filters, and household air Purification filters, transportation vehicle purification filters, smoking room filters, and household appliance purifiers, etc.
