Abstract

Polymer gels are soft, lightly crosslinked polymers that are highly swollen with solvent. The gel properties can be tuned by manipulating the polymer and solvent chemistry, solvent loading, polymer and solvent chain architecture, and the incorporation of various fillers and additives. This tunability provides broad utility in military applications including electronic devices, sensors, robotics, multi-functional textiles, responsive coatings, combat medical care, and tissue surrogates for ballistic testing. While potentially useful, a number of challenges can hinder gel utility for the Army. This paper describes recent efforts that offer promise to overcome these obstacles, including improving operational temperature performance and gel toughness.
