ABSTRACTThe deformation of poly(acrylic acid)—co—(acrylamide) gels and poly(vinyl alcohol)—poly(acrylic acid) gels under an electric field was investigated. Bending of these ionic gels was induced by an electic field. Using this deformation, we constructed a prototype of a robot hand having soft fingers, and an artificial fish able to swim.

PVA and gelatin mixed in various volume ratios (100:0, 90:20, 80:20, 70:30, 60:40, 50:50, to 0:100). The effects of the volume ratio on the spinnability of PVA/gelatin solutions were evaluated. The effect on the electrospun nanofiber of PVA/gelatin was examined by IR spectroscopy. Experimental results have demonstrated that solutions of PVA/gelatin in a volume ratio of 80/20 had good spinnability. As the electric field increased, the numbers of beads and droplet decreased. IR spectra demonstrated strong intermolecular hydrogen bonds between the molecules of gelatin and PVA. In this investigation, the best electric field for electrospinning was 0.68 kV/cm. The critical electric field for electrospinning is 0.5 kV/cm.
