It has been the dream of many scientists to create polymeric materials with simultaneously high dielectric permittivity, low glass transition temperature, and excellent elastomeric properties. Such material would be a highly attractive dielectricum in electromechanical actuators. Within this topic we are focusing on silicones because of their excellent elastomeric properties over a wide temperature and frequency range combined with low glass transition temperatures. To increase their low permittivity, we followed different approaches which include: blending the matrix with highly polarizable conductive and polar nanofillers and chemical modification of the silicones with polar side groups. This AC340presentation will show the advantages and disadvantages of the two strategies we have been following and will provide an assessment of their future potentials.
