Abstract: A method for producing an anisotropic conductive film, which includes mixing a base polymer with an initiator and a first solvent to obtain a first mixture, dispersing conductive microspheres in an alcohol or a second solvent containing a surfactant to obtain a second mixture, mixing the first mixture with a monomer, a binder, and the second mixture to obtain a third mixture, and laminating the third mixture on a carrying film, followed by drying, so as to obtain the anisotropic conductive film. An anisotropic conductive film produced by the method and a composition for forming the anisotropic conductive film are also disclosed.

Abstract: A method for producing a silver-coated polymer microsphere includes admixing a polymer microsphere with a dipping solution containing water, a protic solvent, a tin compound, and hydrochloric acid and subsequently subjecting a resultant first mixture to ultrasonication so that a tin adsorption layer is formed on a surface of the polymer microsphere, immersing the polymer microsphere having the tin adsorption layer in a silver complex solution to obtain a second mixture, diluting the second mixture with water to form a diluted second mixture, and dropping a reducing solution into the diluted second mixture, so that a silver coating layer is formed on a surface of the tin adsorption layer of the polymer microsphere.

Abstract: The invention introduces converging lenses connecting with optical fibers and a device for receiving sunlight that uses these lenses to converge sunlight from every angle of the sun during the day and the collected light beam at the output is quite parallel. To converge light from every angle of the sun, without using any motion part, small lenses are arranged to build a convex surface. Sunlight collected by these lenses become a parallel light beam and are guided by optical fibers. These optical fibers are arranged tightly to build a bundle of optical fibers in order to make it easier to further transmit and to use at the output of the device.
