| Abstract: | The bending characteristics of poly(vinyl alcohol)/poly(acrylic acid) physical crosslinked by repeated freezing thawing the PVA/PAA mixture solution were studied under the d.c. electric fields. The effects of the gel concentration, the composite and the field intensity on the bending speed were investigated in the 0.01 mol/L Na 2CO 3 aqua electrolyte solution. The influence of the electrolyte concentration on the speed was also studied. The bending mechanism under the electric fields was searched after initially. |
