Abstract: An ultraviolet (UV) and infrared (IR) blocking coating and a method for preparing the same are revealed. The coating provides functions of UV blocking and IR blocking by addition of nanoparticles that blocks UV rays and IR rays, or by other additives with the same functions such as organic/inorganic compounds or dyes.

Abstract: This invention relates to a method for making high metallic luster, high impedance on flexible polymer based material, in which a lustrous layer is coated on the first surface of a flexible polymer based material by means of wet coating and a color protection layer is further coated on the lustrous layer or the second surface of the flexible polymer based material. In this manner, metal-like feeling and luster is enhanced by the lustrous layer such that the flexible polymer based material has low metal shielding effect or light-shield capability. In addition, the transmittance of light and electromagnetic wave in demanded range become better so that the interference on the quality of transmission and receiving can be avoided.

Abstract: An ink and a manufacturing method thereof are revealed. The ink includes nanoparticles treated by wet-grinding and surface modification and ultraviolet curing resin, mixed with each other evenly. The ink is applied to manufacturing processes of ink patterns formed by screen printing and followed by chemical plating and horizontal thickening process to add up a conductive layer, especially suitable for manufacturing processes of antennas of RFID systems.
