摘要：

The effect of 7,7,8,8-tetracyanoquinodimethane (TCNQ) doping on the electroconductivity of cross-linked poly[N-[3-(dimethylamino)propyl]acrylamide] (PDMAPAA) gel, swollen in N,N-dimethylformamide (DMF), was investigated. The gel showed ionic conductivity as high as 10(-4) S cm-1 by TCNQ doping due to the formation of an ionic species of the charge-transfer (CT) complex between PDMAPAA gel and TCNQ. It was found that this type of CT gel undergoes rapid contraction by applying dc voltage, and the rate as well as the efficiency of the organogel much exceeded those of hydrogel. The mechanism of such an electrodriven chemomechanical contraction was explained in terms of an electrokinetic process, and the simple mathematical model of the contraction was postulated.
