Methods for forming a polyelectrolyte complex (PEC) film are provided. In embodiments, the method comprises applying a potential between a working electrode and a counter electrode, the electrodes in contact with an aqueous polyelectrolyte solution characterized by a bulk pH. The aqueous polyelectrolyte solution comprises a pH sensitive PEC pair comprising an unmodified anionic polymer and a cationic species, an electrochemical pH agent other than water, and a salt. The applied potential induces an electrochemical reaction of the electrochemical pH agent to generate OH.sup. or H.sup.+ at the working electrode without inducing water electrolysis in the aqueous polyelectrolyte solution, thereby forming a PEC film from the unmodified anionic polymer and the cationic species on a surface of the working electrode.

A superabsorbent polymer includes polymer particles, surface cross-linking agents and particles made of silicon-containing inorganic salt. The polymer particles have cross-linking inside the polymer particles. The surface cross-linking agents are covalently bound to the surface of the polymer particles so as to constitute a surface cross-linked region at the surface of each said resin particle, and the particles made of silicon-containing inorganic salt cover the surface of the polymer particles.
