Layered adaptive membrane structure

摘要

A layered adaptive membrane structure that has movable membranes is provided. The structure can change its gas, liquid and/or particulate permeability in response to surrounding environmental conditions. Applications include protective apparel that is comfortable to wear wherein the level of protection provided is based on conditions in the environment. Hence, the protective apparel is highly breathable and comfortable in a non-hazardous environment but impermeable or only semipermeable in a hazardous environment.
