Efficient particulate matter adsorption material and preparation method and purification mode thereof

The invention relates to the technical field of air purification, in particular to an efficient particulate matter adsorption material and a preparation method and purification mode thereof. The preparation method comprises the following steps of: preparing a carbon nano tube solution, weighing carbon nano tubes, dissolving the carbon nano tubes in water, and diluting the solution to corresponding concentration; preparing a mixed dissolving solution, weighing a proper amount of polyvinyl alcohol and polyethylene glycol, putting the polyvinyl alcohol and the polyethylene glycol into a container, adding the carbon nanotube solution into the polyvinyl alcohol and the polyethylene glycol, and dissolving in a water bath; preparing a film material, and coating a screen window with the dissolved mixed dissolving solution through a scraper machine; and taking out the screen window, and naturally air-drying and then uncovering the film material. The film material provided by the invention has the characteristics of go
