Multiscale Modeling of Polymer Membranes for Soldiers Protective Clothing

Abstract

The development of protective and breathable clothing is a very important goal set for the Future Force. Recently, a new polymer membrane made of an ionic triblock (A-B-A) copolymer was developed at the U.S. Army Research Laboratory (ARL) that provides an excellent selective barrier for soldier s protective clothing. We have used multiscale modeling to gain an understanding of the static and dynamic properties of this polymer membrane at detailed atomistic and mesoscale levels. These simulations lead to the prediction of the architecture and morphology of the membrane. We have also studied mesoscale morphology of the copolymer constrained by a surface or the nanopore. Mechanical properties of copolymer were calculated using the self-consistent homogenization theory.
