Fibers for Decontamination of Chemical and Biological Agents

CTCN Keyword Matches:

Threats arise from biological and chemical hazards such as warfare incidental chemical spillage and outbreak of infectious diseases. This invention incorporates nanoparticles in nanofibers to effectively detoxify biological and chemical agents. Disposal or avoidance of hazardous agents requires protective clothing and decontamination/ detoxification agents. Current methods include Activated charcoal DS2 and XE55™ but they have inherent limitations. Activated charcoal is heavy in weight and detrimentally retains moisture. Decontaminating Solution 2 (DS2) has low reactivity is highly corrosive and releases toxic by-products. Xe55™ resin is highly expensive does not possess sufficient neutralizing properties and releases toxic gases when mixed with the sorbent. This invention proposes a novel material based on metal oxide nanoparticles and nanofibers which provide lightweight low cost highly reactive non-toxic products after decomposing chemical and biological agents. Breathable structures with improved protection duration and performance can be used in for example protective garments face masks and filtration systems. The nanocomposite membrane allows air to pass through and adsorb hazardous agents selectively while the presence of pores helps enhance adsorption. Technology Features: Fibers synthesized by electrospinning; Filtration or decontamination can be customized by varying different proportions of nanoparticles incorporated in the nanofibers. Patent: Pending; Exclusive / non-exclusive Licensing; Partnership in commercial development
