dc.description.abstract | Chemical warfare agents (CWAs) cause death, injury, temporary disability, and sensory stimulation when they come in contact with the skin or the respiratory system. CWAs move by diffusion; therefore, it is essential to control the pathways that they traverse. CWAs move through the spaces between graphene oxide (GO) sheets within a stacked GO film. Here, we demonstrate that GO nanosheets with high surface charge density offer protection performance. Our results reveal that the interlayer distance between the GO nanosheets depends on the surface charge density of the GO nanosheets. The protective effect of GO membranes is investigated using vapor transmittance rates (DVTRs) of dimethyl methylphosphonate (DMMP), a nerve gas simulant, and water vapor transmittance rates (WVTRs). The DVTR of GO membrane is decreased from 213.24 g/m2 day to 132.48 g/m2 day as the distance narrows. These results demonstrate that applying extremely thin GO membranes to protective clothing and masks can prevent the diffusion of CWAs even without special treatment. | - |
