Abstract
The present disclosure relates to the field of dielectric elastomers. In particular, provided are a dielectric elastomer precursor fluid, a preparation method therefor and the use thereof, a dielectric elastomer composite material, a flexible device, and a light-emitting device. The dielectric elastomer precursor fluid comprises an elastomer matrix, an ionic liquid and a solvent, wherein the volume fraction of the ionic liquid and the solvent is 5-45%. The dielectric elastomer precursor fluid has the advantages of a high conductivity, a high transparency and a good fluidity, and is beneficial for preparing a dielectric elastomer composite material having a high dielectric constant, a low elastic modulus and a high optical transparency, thus fully solving the problem that a high dielectric constant cannot be balanced with a low elastic modulus and a high optical transparency in a dielectric elastomer.
