This application relates to omniphobic materials which are physically and chemically modified at their surface to create hierarchically structured materials with both nanoscale and microscale structures that provide the omniphobic properties. Methods of making such omniphobic surfaces with hierarchical structures and uses thereof, including as flexible films that repel contaminants are also disclosed in the application.

A composite sheet includes a resin layer including a liquid crystal polymer as a main material and a first surface and a second surface facing away from each other, a conductor foil disposed on the first surface, and a powder layer including a powder of a liquid crystal polymer as a major component and located on an entirety of the second surface.

The present invention provides a method for forming a metal pattern on a pattern formation section set in a part or the whole of a region on a base material, the base material including a fluorine-containing resin layer on a surface including at least the pattern formation section, the method including the step of: forming a functional group on a pattern formation section of the fluorine-containing resin layer by a treatment such as ultraviolet-ray irradiation, then applying to the surface of the base material a metal fine particle dispersion liquid in which metal fine particles protected by an amine compound as a first protective agent and a fatty acid as a second protective agent are dispersed in a solvent, and fixing the metal fine particles on the pattern formation section.

This invention provides a method for manufacturing a decorated part having a dynamic visual effect of a design that is drawn onto the surface of a work, thus reducing the manufacturing cost. The decorated part is manufactured by a laser-irradiating process, which involves irradiating a laser onto a decorative surface 4, thus forming a design 20 having many laser-processed linear grooves 21 closely aligned in a specific direction F1 on said decorative surface. Also, in the laser-irradiating process, said design 20 is formed such that the angle θ2 that is made by the specific direction F1 and by the direction F2 in which the laser-processed linear grooves 21 are extending is gradually changing into the direction in which such laser-processed linear grooves are aligned.

A method for in-site synthesis of transparent conductive coating of poly(3,4-ethylenedioxythiophene)/nano silver hybrid on transparent substrate is provided. Transparent substrate with oxidant coating containing silver salt is immersed into 3,4-ethylenedioxythiophene (EDOT) solution. The oxidant turns EDOT monomer to poly(3,4-ethylenedioxythiophene) (PEDOT) coating on the transparent substrate; meanwhile, the silver salt itself is reduced to nano silver by the EDOT monomer, resulting in a nano silver-doped PEDOT coating. Thereby, a transparent conductive film made of PEDOT/nano silver coating on transparent substrate is obtained. The transparent conductive film with PEDOT/nano silver coating prepared in the present invention possesses the advantages of high electrical conductivity, optical transparency and environmental stability.
