Description

technical field [0001] The invention relates to the technical field of air filtration, in particular to an air filter paper containing carbon nanomaterials and a preparation method thereof. Background technique [0002] Air filter paper is widely used in national defense industry, electronics industry, medical and health care, pharmaceutical industry, food processing and other industries, and is a commonly used air filter material. Air filter paper is made of superfine fibers through wet papermaking. Its main purpose is to filter the air and remove particles in the air. The smaller the fiber diameter of the filter material, the smaller the particle size for removing particles in the air, and the higher the filtration efficiency. Compared with traditional fibers, nanofiber materials show better filtration performance, and carbon nanomaterials have great Small nanoscale diameter, huge specific surface area, excellent adsorption performance, super mechanical properties, these ...
