Oike ITO conductive film

Product Name: ITO conductive film Brand: Oike Thickness: 50um 125um 188um surface resistance: 150Ω 300Ω transmission rate: ≥ 85% Haze: <2% Specifications: 510mm × 100m 350mm * 100m Features: no etching marks, aging ( heat treatment) after stable electrical performance, high transmittance Products: in the range of visible light, the light transmittance and conductivity film plating rate of approximately inversely proportional relationship between ITO conductive film; for example, when the coated surface resistivity in 10Ω / sq below , visible light transmission rate of up to 80%, but if the light transmittance is intended to meet more than 90%, the sheet resistance must be increased 100Ω / sq or more. Transparent conductive film made of a conductive material and special materials made of polyethylene, with good performance and mechanical properties of electrostatic discharge color: transparent glossy, translucent matte, plus hard grade, anti-scratch (ordinary, optical grade ) thickness: 125. ITO conductive film is the use of magnetron sputtering (prepared ITO conductive film evaporation, sputtering, reactive ion plating, chemical vapor deposition, spray pyrolysis, etc., but the most used is reactive magnetron sputtering) , on a transparent organic film material sputtered indium tin oxide transparent (ITO) thin film layer and the conductive after high temperature annealing treatment to obtain high-tech products. Different thickness of the ITO film, the transparent conductive properties and properties of the film are also different. In general, in the case of the same process conditions and the same performance of PET base material, ITO film layer thicker, the surface resistance of PET-ITO film is smaller, light transmittance is correspondingly smaller. Low impedance conductive ITO films can be used to require a relatively high conductivity, such as: a transparent electrode for thin film solar cells, the electrode material electrochromic devices, membrane switches and other fields. Ultraviolet light transmittance ITO conductive film is extremely low. While the near-infrared region due to carriers of plasma vibration phenomena arising reflection, so the light transmittance in the near-infrared region of the ITO conductive film is very low, but the transmittance in the visible region of the ITO conductive film is very good, since the material itself specific physical and chemical properties, ITO conductive film having good electrical conductivity and high optical transmittance in the visible region. ITO conductive film conductive properties affect several factors ITO film surface resistance (R), the film thickness (d) and resistivity (ρ) between the three are interrelated, calculated between these three is: R = ρ / d. As can be seen from the formula, in order to obtain different surface resistance (R) of the ITO film, in fact, is to obtain different film thickness and resistivity. In general, you want to get a different film ITO conductive film preparation time
