摘要:
The invention provides an organic/inorganic hybrid material and the method for manufacturing the same. A variety of functional monomers are co-polymerized to form a copolymer. The copolymer is subjected to sol-gel reactions with metal alkoxide oligomers to form an organic/inorganic hybrid material. The hybrid material has a high refractive index, a low moisture absorption, a high light transmission ratio, and a high glass transition point, such that the material can be applied in high light extraction efficient LED sealing materials, thin and light myopia/hypropia lens, portable projector lens, high brightness LCD prism films, solar cell refractive photoelectric conversion mirrors, and camera phone/digital camera lens.

摘要:
A method for packaging a light emitting diode is provided. The steps comprise: providing a material; drying the material; feeding the material into a feeding inlet; and providing a mold with pre-embedded light diodes. The material enters the feeding inlet and is injected into the mold by pressing a screw, allowing the material to combine with the light emitting diode.
摘要:
A processing method of a polymer product is provided. This method first supplies a gas to an atmospheric pressure plasma machine to generate an ionized gas. Then, bombard the ionized gas to the surface of the polymer product to create a surface reaction. Afterwards, a dying treatment or an electroplating treatment is performed on the polymer product.

A method of adjusting a surface characteristic of a substrate is provided, which includes the following steps. A substrate is provided. An atmosphere pressure plasma process is performed on the surface of the substrate to form a film layer on the surface of the substrate, so as to adjust the surface energy of the substrate, wherein a process gas of the atmosphere pressure plasma process includes a surface modifying precursor, a carrier gas and a plasma ignition gas. In particular, the surface modifying precursor is selected from fluorosilane, polysiloxane and a combination thereof, and the ratio of fluorosilane to polysiloxane is between 0 and 1.
