Abstract : Stimuli responsive hydrogel systems have been studied for many applications, particularly in the medical and biological applications. For future soldiers, the Army as an interest in smart textiles capable of better managing a soldiers comfort by regulating moisture and thermal properties. Hydrogel or microgel textile coatings are of interest particularly for cold weather and Arctic uniforms. The effect of extreme cold on gel responsiveness however is not well studied. This project seeks to understand the effect of cold temperature (down to -80 C) on hydrogel and microgel particles properties and response to thermal stimuli. We chose three common gel systems for study: Poly N-isopropyl acrylamide (PNIPAAm) LCST 25-30 C; Polyethylene glycol (PEG); and Polyacrylic acid (PAA)UCST 25-30 C
