Abstract
Disclosed herein are novel materials and methods of forming those novel materials. The materials are synthesized from Poly(acrylic acid), a crosslinker; and a salt. The material can be further synthesized from sodium hydroxide. The crosslinker can be a covalent crosslinking agent such as N,N'-methylenebisacrylamide. Examples of applicable salts are calcium chloride, lithium chloride, zinc chloride, sodium chloride, potassium chloride, barium chloride, cesium chloride, magnesium chloride, cobalt chloride, lithium bromide. In example, the Poly(acrylic acid) can be about 3 moles of Poly(acrylic acid), the crosslinker can be about 0.005 moles of N,N′-methylenebisacrylamide, and the salt can be formed by the addition of about 0.003 moles of potassium persulfate.
