Haze is a special weather phenomenon caused by the current environmental pollution. Haze generally contains certain PM2.5 and PM10 particles, and can enter a respiratory system through the nasopharynx part of a human body, so that the damage to the functions of main organs such as heart and lung is caused, and the symptoms of dryness, itching, stabbing pain, bleeding, cough, expectoration, chest distress, palpitation and the like of the nose and throat part are often presented. The continuous haze contact can cause lung cancer, myocardial damage, infertility and other diseases, and the health and the daily life of human beings are greatly damaged. At present, people mainly adopt air filter material to alleviate the influence that the haze brought. The commonly used air filter material is mainly prepared from synthetic fibers of plastics such as polypropylene, polytetrafluoroethylene and the like, which brings difficulty to recycling of waste products, and causes environmental pollution easily due to improper treatment, so that the environment-friendly multifunctional material becomes one of the future development trends of the air filter material market. Due to the advantages of cost and strong functionality, biopolymers and their polymers have led us to focus on the development of environmentally friendly air filtration materials.
