A composite with hollow nano-structures includes multiple one dimensional hollow nanowires being dispersed into a polymer film. The polymer film is flexible, a dielectric constant of the one dimensional hollow nanowire is lower than a dielectric constant of the polymer film, and a dielectric constant of the composite is between the dielectric constant of the one dimensional hollow nanowire and the dielectric constant of the polymer film.

Composite with hollow nano-structures and application thereof

A method for manufacturing a copper foil with a rough surface in a plating tank includes causing an electrolyte solution to flow between an anode and a cathode with a current density of 5 ASF-40 ASF. The copper foil with a rough surface including dense nodules of single copper crystals is deposited on the cathode. The electrolyte solution includes chloride ions (20 ppm-80 ppm), polyethylene glycol (PEG) with a molecular weight of 400-8000 (100 ppm-700 ppm), sulfuric acid (20 g/L-200 g/L), copper sulfate pentahydrate (70 g/L-320 g/L) and a sulfur compound (1 ppm-60 ppm).

Non-conductive substrates, especially the sidewalls of micro/nano holes thereof are chemically modified (i.e., chemically grafted) by reduced graphene oxide (rGO). The rGO possesses excellent electrical conductivity and therefore the modified substrates become conductive, so that it can be directly electroplated. These rGO-grafted holes can pass thermal shock reliability test after electroplating. The rGO grafting process possesses many advantages, such as a short process time, no complex agent (i.e., no chelator), no toxic agents (i.e., formaldehyde for electroless Cu deposition). It is employed in an aqueous solution instead of an organic solvent, and therefore is environmentally friendly and beneficial for industrial production.

Method for modifying surface of non-conductive substrate and sidewall of micro/nano hole with rGO

The method for producing a transparent conductive substrate includes forming metal meshes on a flexible non-conductive substrate with high transmittance. It's unnecessary to use palladium as a catalyst in this method. The metal meshes are in the form of nano/micro wires and the conductive substrate has high transmittance of 80%-90% at visible light wavelengths of 390-750 nm.

Method for producing flexible conductive substrate with high transmittance and product thereof

A method for coating a layer of reduced graphene oxide (rGO) on the surface of substrate holes (especially holes with high aspect ratio) includes a serial wet process steps of hydrophilic treatment of the surface of the substrate, self-assembly of a silane layer, steps of grafting of a polymer layer, grafting of graphene oxide (GO), intercalation of metal ions, and intercalation of metal atom/rGO intercalation. The method further includes the decoration of conductive metals (copper or nickel tungsten) plug on the rGO layer in holes by electroplating process.
