ASC carbons were treated humidification and thermal regeneration by different recycle times, respectively. Several methods included that, Moisture contain measurement, N2 isotherms (BET) measurement, Scanning Electron Micrograph (SEM), Electron Spectroscopy for Chemical Analysis (ESCA), Thermal Gravimetric Analysis (TGA) and Differential Scanning Calorimeter (DSC) were employed in this study for analyzed the variations of ASC carbon. On the other hand, the protective performances were contrasted original carbon with 80 ± 6 % for the residual adsorption of hydrogen cyanide of the regenerative carbons. Polyethylenimine (PEI) has nucleophilic amine groups, which can react with electrophilic species such as sulphur mustard and soman. Polyvinyl Alcohol (PVA) is excellent gas barriers. In this study, the blend polymers were prepared for the layers in protective clothing. The variations of different weight ratio of blending membranes were analyzed by FT–IR and DSC. From these results, a further investigation will be carried out in our laboratory to develop the selectively permeable membranes.
