A fabric containing nanotubes which is impervious to viruses, bacteria, and other pathogens; which is self-sterilizing and reusable; and a method of producing the same are disclosed. The fabric can be used to construct facemasks, gloves, protective suits, protective habitats, continuous air filtration/sterilization systems or any other type of protective clothing or structure. The fabric may have integrated temperature monitoring sensors. The fabric may be made into patches which may be integrated into existing articles of clothing. When connected to an electrical power source, either via built-in electrical connections or by induction, the active layer which is one of the components of the fabric will heat to a temperature high enough to eliminate potential biological contamination from viruses, bacteria and other microbial threats. Combining the CNT active layer with an insulating layer will allow a garment to be continuously worn or used without needing removal during multiple sterilization cycles.
