Abstract
A binder-free conductive ink with a conductive cage architecture for the wireless antenna with adhesion enhancement by carbon powders that aims to enormously reduce the solid content of conductor and can be used to print antennas. For example, silver content of the ink composition is greatly decreased due to the absence of insulated binder. Carbon powders (such as graphene nanoplatelets) are added as a conductive 'cage' to reduce the use of insulated binder and significantly improve the conductivity of ink under low addition of conductor. Compression after printing is an innovative finding that not only improves the adhesion of a binder-free conductive ink with a conductive cage architecture but also enhances its conductivity. Such effects are credited to excellent contact between interfaces of particles and substrate. The unique recipe and process save printing from high-temperature sintering, further reducing processing cost and widening applicable substrates.
