Abstract: A composition of matter includes a solid resin powder containing one or more polymer precursors in a range of 80-99.99 wt % polymer precursor and the thermal initiator in a range of 0.001 to 20 wt % of thermal initiator. A composition of matter includes a solid resin powder containing polymer precursors comprising two components in a combination and a thermal intiator, wherein the combination comprises one of a solid epoxy with one of solid amine or anhydride, a powder resin containing both epoxy and one of either amine or anhydride, or two powder resins wherein one contains epoxy and one contains one of either amine or anhydride.

Abstract: A weak base anion resin has alkylamine segments covalently bound to cross-linking segments, the alkylamine segments being selected from a group consisting of: vinylamine, N-methylvinylamine, N,N-dimethylvinylamine, N-methyl-N-ethylvinylamine, and N,N-diethylvinylamine, and the weak base anion resin including ions adsorbed to the alkylamine segments. A method for ion exchange includes providing a weak base anion resin, contacting the weak base anion resin with a solution containing ions to one of capture or adsorb ions from solution to the weak base anion resin, and regenerating the weak base anion resin. A method to capture and release an acid gas includes providing a weak base anion resin, contacting the weak base anion resin with a gas including an acid gas to one of capture or adsorb the acid gas from the gas to the weak base anion resin, and regenerating the weak base anion resin to release the acid gas.

Abstract: A method to produce a polymer gel includes dissolving precursors in a solvent to form a precursor solution, the precursors including polymer precursors, a stable free radical, one or more initiating radicals, and one or more stable free radical control agents, and heating the precursor solution to a temperature of polymerization to produce a cross-linked gel. A dried polymer aerogel has a Brunauer-Emmett Teller (BET) surface area over 100 m2/g, porosity of greater than 10%, visible transparency greater than 20%, color rendering index of over 20%, and average pore size of less than 100 nm.

Abstract: A sensor has a transparent polymer aerogel, and sensing materials dispersed into the transparent, polymer aerogel, where the sensing materials change color in response to environmental conditions. A method of forming a sensor includes providing a substrate, forming a polymer aerogel layer on the substrate, and infusing the polymer aerogel layer with sensing molecules.
