技术介绍
导电涂料是伴随现代科学技术而迅速发展起来的特种功能涂料,近几十年来的研究和发展,导电涂料己在电子、电器、航空、化工、印刷等多种军、民用工业领域中得到应用。在现有透明导电材料应用中使用最普通的是ITO镀膜材料,它的制备方法是在透明有机薄膜材料上溅射透明氧化铟锡(ITO)导电薄膜镀层得到的产品。该产品的特点是,以在PET膜上为例,ITO膜层越厚其表面电阻越小,但透光率也变小。如:高阻抗ITO导电膜(PET-ITO),表面电阻300~500Ω/口,透光率≥86%,表示硬度≥3H,加热卷曲≤10mm;低阻抗ITO导电膜(PET-ITO),表面电阻90±15Ω/□,透光率≥80%,雾度<2%,宽度406/360±2mm,卷曲≤10mm;最高端的ITO膜透光率≥90%,表面电阻≤100Ω/□;但ITO膜存在几个方面的不足,一是由于其涂层硬镀、折弯性差,二是涂布面积受限,三是铟锡资源匮乏,不宜于可持续发展设备昂贵,工艺流程长,成本降不下来等,固而研发ITO的 ...
