Also provided is a method for preparing a super-hydrophobic (SH) surface, where the method includes mixing an NP component with at least one RI and possibly with a fluid, thereby providing a coating composition, applying the coating composition onto a substrate (pre-coated or containing oxides) thereby providing a coated substrate; and applying radiation to the coated substrate, thereby providing the SH surface on which at least part of the NP component is covalently bound, directly or indirectly, to the substrate.

A composition for forming a conductive film contains flat metal particles and a resin. The flat metal particles each have a metal oxide layer in the surface portion thereof. The flat metal particles have a ratio of the thickness of the metal oxide layer to the thickness of the flat metal particle of from 0.010 to 0.300.

In the method for manufacturing a conductive film, a composition for forming a conductive film is used, the composition containing flat metal particles and a resin. The composition for forming a conductive film is applied to a base material to form a coating film, and then the coating film is irradiated with light to sinter the coating film, thereby obtaining a conductive film. The flat metal particles each have a metal oxide layer in the surface portion thereof.

Provided herein are highly conductive compositions (having a volume resistivity no greater than 110.sup.3 Ohms.Math.cm) using silver flake, powder or suspension in solvent for electromagnetic interference (EMI) applications. This high conductivity will allow the use of very thin films for EMI shielding protection, which in turn will be helpful to reduce package sizes. In some embodiments, the coating composition is applied on the device surface by suitable means, e.g., by an electrostatic spray process, air spray process, ultrasonic spray process, spin coating process, or the like.
