| Abstract Scope |
Elastomers, such as butyl rubber, have traditionally been used to provide a barrier against chemical and biological (CB) penetration, such as in the case of gloves. However, these moisture vapor impermeable materials increase insulation and impede evaporative cooling, thereby increasing thermal burden. Also, these materials greatly impair manual dexterity and tactile sensations compared to bare hand performance. Therefore, a need exists for thin, durable, CB repellent, elastomeric based materials. The Defense Threat Reduction Agency’s Chemical and Biological Technologies Department is invested in fundamental understanding of how to develop and integrate two-dimensional materials for increasing the multi-functionality of elastomer nanocomposites. Approaches consider both mechanism of incorporating chemical agent protection (agent repellency) on elastomeric surfaces and limiting the physiological burden (and thermal and mobility) that reduces user effectiveness. This talk will highlight the recent developments from ongoing research in 2D@CB. |
