NOVELTY - Fresh air energy recovery membrane comprises active carbon powder, an antibacterial material, a formaldehyde removing functional material and a three-dimensional network polymer. The active carbon powder, the antibacterial material and the formaldehyde removing functional material are uniformly coated in the three-dimensional network polymer to form the recovery membrane. USE - Fresh air energy recovery membrane. ADVANTAGE - The recovered film has high tensile strength of 137 mega Pascal, elongation at break of 53%, high thermal conductivity of 2 .277W/(m.K), heat shrinkage of 3 .9% and moisture permeability of 361g/(m2h). The film has an extremely low surface friction coefficient, smaller wind resistance than other material film materials, and self-cleaning effect and does not absorb dust eaily. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing fresh air energy recovery film, which involves calculating the addition amounts of a solvent, a dispersing agent, a monomer, a cross-linking agent, activated carbon powder, an antibacterial material and a formaldehyde removal functional material according to experimental requirements; weighing the materials, and respectively and sequentially adding the materials into a ball milling tank; placing the ball milling tank on a ball mill for ball milling to obtain slurry; conveying the slurry into a forming die for curing to obtain a green body; and placing the green body into a temperature and humidity drying box for drying.
