Enhancing adsorption efficiency for camouflage clothing through activated carbon and inorganic composite coatings

This research aimed to study the feasibility of using activated carbon and other powder materials (TiO 2 , Talc and Bentonite) as a coating for military camouflage clothing, which can provide economic and accessible protection against chemical warfare agents and some types of radiation. The camouflage material was coated through a powder and thermal coating process and analyzed. The process’s protective efficacy was analyzed by a scanning electron microscope (SEM), examining pore size distribution, UV–Vis NIR, and atomic adsorption spectroscopy (AAS). SEM images of military camouflage texture treated with activated carbon, Talc, TiO 2 and Bentonite in 50x, 100x, 200x, 400x, 800x and 1,000x magnifications reveal composite materials between powder materials and binder composites in the camouflage texture, arranged in an organized amorphous configuration. The pore size analysis found that the pore size distribution of activated carbon, Talc, TiO 2 and Bentonite stood in the range of micropores (0.020–0.094 cm 3 /g). The UV–Vis–NIR spectrum analysis discovered that the synthesized clothing sample with the AC/TiO2/Talc/Bentonite composite is an effective method to reduce noise, especially in the UV–Vis region. The adsorptive behavior of Arsenic (AS) and Lead (Pb) showed differences in the rank of qualities of chemisorption. The research found that the military camouflage coated with AC/TiO2/Talc/Bentonite composite had the best performance in providing protection.
