Abstract:

Butyl Rubber BR is a highly effective barrier material fabric liner with excellent chemical stability and low permeability toward organic solvents and reactive chemicals. However, it has poor air and water vapor permeability. Used as a liner in protective clothing against chemical warfare agents, this disadvantage can lead to fatigue and heat stress in wearer. But blend BR with lyotropic liquid crystals LLCs form inverted hexagonal HII phase, creating a nanoporous breathable LLC-BR composite.
