Reversible Molecular Closure System for Shelters and Clothing

Luna will develop a hermetic closure system for use on combat uniforms and shelters that require protection from chemical and biological (CB) warfare agents. Despite great advances in high barrier fabrics, selectively permeable membranes, and unique chemical absorbent technologies, closures for clothing and shelters still possess the greatest risk for chemical or biological breach. Instead of molecular diffusion through a fabric, chemical aerosol, vapor, or liquid penetration is possible at penetration points such as i) CB protective shelter (CBPS) entrances; ii) connections points for the Joint Service Lightweight Suit Technology (JSLIST) between suit and mask, gloves, and boots. Various mechanical devices have been developed to solve this problem and have resulted in devices which are stiff and possess poor chemical barrier and strength. Luna's novel approach will make use of high strength closure system with a unique reversible adhesive layer, which will have high strength, flexibility, and moreover be a high barrier to contaminant permeation.
