Abstract: The present disclosure relates to an elastomer-conductive filler composite for a flexible electronic material having improved dielectric property and elastic modulus, and a method for preparing same. The elastomer-conductive filler composite according to the embodiments of the present disclosure solves the problem of the existing insulator-conductor composite that elastic modulus increases and adhesion property decreases with the increase in dielectric constant as the content of the conductive filler in elastomer increases. In particular, since the composite has a high dielectric constant in spite of a low content of the conductive filler and since the elastic modulus increased because of the conductive filler can be recovered by the plasticizer, the sensitivity of a sensor can be improved. Accordingly, it can be usefully used for flexible substrates and flexible touch panels or touchscreens, touchpads, etc. including them.

Abstract: A metallic-dielectric photonic crystal is formed with a periodic structure defining a plurality of resonant cavities to selectively absorb incident radiation. A metal layer is deposited on the inner surfaces of the resonant cavities and a dielectric material fills inside the resonant cavities. This photonic crystal can be used to selectively absorb broadband solar radiation and then reemit absorbed radiation in a wavelength band that matches the absorption band of a photovoltaic cell. The photonic crystal can be fabricated by patterning a sacrificial layer with a plurality of holes, into which is deposited a supporting material. Removing the rest of the sacrificial layer creates a supporting structure, on which a layer of metal is deposited to define resonant cavities. A dielectric material then fills the cavities to form the photonic crystal.
