Fund Project: This work is supported by the National Natural Science Foundation of China (Nos. 20736002, 20706013), Program for Changjiang Scholars and Innovative Research Team in University (No. IRT0721) and the 111 Project (No. B08021).

Polyvinyl alcohol/polyacrylamide semi-interpenetrated hydrogels were prepared via freeze-thaw process. When a 20 Vof DC was applied across the gels, the gels with lower polyacrylamide content underwent a contraction or partly turned into solution, while for the gels with higher polyacrylamide concentration, a complete gel-sol transition was observed in a short time.
