Abstract: Binder-free conductive carbon ink is printed on flexible polymeric substrates such as PET and paper as an antenna for wireless devices. Without addition of binder, conductivity of the carbon ink can be greatly improved. Owing to the enhance of conductivity, carbon ink proposed in this patent can be applied to antenna application, such as RFID, without the utilization of metal or metal coated powders, and enormously decreases the antenna cost. The excellent adhesion to substrate results from the size and shape match between carbon powders and pores of substrates. Further compression and protective coating will further enhance adhesion of antenna.

Abstract: A novel method of producing sub-nanometer grade surface finishing substrates comprises the following steps of: producing a mother substrate which has ultra fine finished surface; a sacrificial layer being employed on a top of this layer being used to facilitate the depletion of finished product with this mother substrate; after finishing the sacrificial layer, a vacuum tool being used to deposit a thin layer on the top of sacrificial layer, wherein this sacrificial layer is remained as a surface of a finished product. To further increase a thickness of the thin layer, vacuum tool or an electroplating method are employed. After reaching a predetermined thickness, the fine surface finishing layer will be bonded with a bulk substrate; bonding of these two objects being done by vacuum bonding with elevated temperature and pressure; and therefore, a fixture is used.
