Liquid-Crystal Rubber Suit Prevents Overheating
Military personnel, chemical workers, and others could benefit from a new synthetic rubber material tailored with liquid crystals. The material might be used to make body suits to protect chemical-industry employees from skin exposure to toxic vapors and aerosols, as well as providing protection for military personnel and civilians in the event of a chemical weapons attack.
The ideal protective garment should be lightweight and selectively block toxic vapors, but be “breathable,” allowing water vapor to pass outward, thereby maintaining personal comfort and safety. As described in a recent issue of Advanced Materials, Douglas Gin of the University of Colorado, Brian Elliott at TDA Research Inc. (Wheat Ridge, Colo.), and colleagues have now developed just such a material based on modified butyl rubber. The material is breathable but also rejects chemical agents.
