Abstract
A composite of a substrate having an application of superabsorbent polymer. The composite is made by applying, directly onto the substrate, an application of a polymer that will, upon being subjected to radiation, convert to a superabsorbent polymer. The substrate with applied polymer is subjected to radiation, such as being heated at a sufficient temperature for a sufficient time, to obtain the composite of substrate with superabsorbent polymer adhered to it.
