Title:
NANOPILLARS, METHOD FOR FORMING SAME, AND BONDED MATERIAL, BATTERY, DEVICE FOR CARBON DIOXIDE GAS RECOVERY/RETENTION, AND MODULE FOR ELECTRIC-POWER CONVERSION APPLIANCE WHICH ARE OBTAINED USING SAID NANOPILLARS
Document Type and Number:
WIPO Patent Application WO/2014/119421
Kind Code:
A1
Abstract:
The present invention is a method for forming nanopillars comprising a metal oxide on the surface of a metal, wherein the interface between the metal and water that is in contact with the metal is irradiated with light having a wavelength of 185-800 nm. It is desirable to roughen the surface of the metal before the irradiation with light. Due to this, a plurality of acicular, columnar, rod-shaped, or other nanopillars can be simultaneously formed on the surface of the metal so as to cover the surface, the nanopillars being constituted of crystals based on an oxide of the metal.
