Author Affiliations +
Electric-, and magnetic field sensitive polymer gels are soft smart materials whose elastic and thermodynamic properties are strong function of the field strength imposed upon them. Since electric and magnetic fields are convenient stimuli from the point of signal control, therefore it is of great importance to develop and study such gel systems. In the first part of this paper we introduce a new concept to classify responsive polymer gels. Then it is followed by the discussion of a new driving mechanism which was discovered to induce deformation and movement of neutral polymer gels in non-conducting medium. Bending of weakly crosslinked poly(dimethyl siloxane) gels containing finely distributed TiO2 particles as well as colloidal iron particles has been studied in silicon oil. Under electric field these gels undergo a significant and quick deformation.
