Abstract: A method of manufacturing a hexagonal boron nitride laminate contains steps of: a) Dissolve dielectric polymers in solvent. b) Mixing h-BN powder to form a well-mixed h-BN coating slurry. c) Coating slurry on substrates and dried at 100-150° C. The substrates can directly be etched or processed to form electric circuits. Substrates can also be completely etched or detached to attain a free standing laminate. Thereby, a hexagonal boron nitride laminate exhibit thermal conductivity of 10 to 40 W/m·K, which is significantly larger than that currently used in thermal management. In addition, thermal conductivity of hexagonal boron nitride laminates increases with the increasing mass density, which opens a way of fine tuning of its thermal properties. For heat dissipation application, hexagonal boron nitride laminate coating can significantly enhance the performance of LED light bulb.

Abstract: A conductive ink composition for the wireless antenna with adhesion enhancement by carbon flakes 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 flakes (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 but also enhances the 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.
