Laser-induced graphene filters and methods of making and using same

Killing viruses and microorganisms, self-disinfecting resistive hot air filters and methods of making and using the same. Air filters include laser induced graphene (LIG), porous conductive graphene foam formed by photothermal conversion of a polyimide film (or a source or another source of polymer or other LIG precursor material) by a laser source. LIG in the air filter can capture particles and bacteria. And bacteria cannot proliferate even if immersed in the culture medium. Through a periodic Joule heating mechanism, the temperature of the filter is easily higher than 300 DEG C. This destroys any microorganism, including bacteria, as well as molecules that may cause adverse biological reactions and diseases, such as viruses, pyrogens, allergens, exotoxins, endotoxins, teichoic acids, mycotoxins, nucleic acids, and prions. 杀灭病毒和微生物、自消毒电阻式热空气过滤器以及制造其的方法和使用其的方法。空气过滤器包括激光诱导石墨烯(LIG)，即通过激光源对聚酰亚胺薄膜(或聚合物或其他LIG前体材料的来源或另一来源)进行光热转换而形成的多孔导电石墨烯泡沫。空气过滤器中的LIG可以捕获微粒和细菌。细菌即使浸入培养基中也不能增殖。通过周期性焦耳加热机制，过滤器很容易达到高于300℃。这会破坏任意微生物，
