Abstract

本实用新型的结构是，柔性基材PET聚酯塑料膜4的一侧表面有由下至上依次为锌铝氧化物膜层3、铟锡氧化物膜层2、锌铝氧化物膜层1构成的复合层。本产品电阻在高温下具有良好的稳定性，且透光度和柔性好，广泛适用于触摸屏、EL光源、透明薄膜加热器、透明静电屏蔽、透明除霜雾等。

Description

一种高稳定的柔性透明导电复合膜
技术领域
本实用新型涉及主要用于触摸屏、EL光源、透明薄膜加热器、透明静电屏蔽、透明防霜雾等的透明导电膜。
背景技术
现有技术产品是于低温下在柔性基材PET膜上镀一层铟锡氧化物(ITO)膜，由于低温成膜造成ITO膜氧空位浓度较高，并且膜结构比较疏松，因此在较高温度下ITO膜电阻值变化较大，很难满足使用要求。
技术内容
本实用新型的目的是，研制出一种高稳定的柔性透明导电复合膜，在高温下具有良好的电阻值稳定性，且透明度、柔性均很好。
本实用新型的技术方案是，所述高稳定的柔性透明导电复合膜的结构是，它有柔性基材PET聚酯塑料膜，其技术特点是，在该PET聚酯塑料膜的一侧表面有由下至上依次为锌铝氧化物膜层、铟锡氧化物膜层、锌铝氧化物膜层构成的复合层。
以下对本实用新型做出进一步说明。
参见图1，本实用新型有柔性基材PET聚酯塑料膜4，其结构特点是，在该PET聚酯塑料膜层4的一侧表面有由下至上依次为锌铝氧化物(ZAO)膜层3、铟锡氧化物(ITO)膜层2、锌铝氧化物(ZAO)膜层1构成的复合层。产品采用镀制工艺在所述柔性基材上镀制多层透明导电膜而构成复合膜。
本实用新型的设计原理是，利用锌铝氧化物和铟锡氧化物复合，有效解决了已有技术产品高温下阻值不稳定的问题。其中，锌铝氧化物成膜结构致密、透明度好，但电阻率较大；铟锡氧化物成膜透明度好、电阻率较小。所成复合膜产品性能优良，透光率(550nm)达85％以上，表面电阻线性度(在300mm长度上)＜1％，表面电阻400Ω/口±5％，热稳定性好：150℃，30分钟，(R/R0)＜1.1。
由以上可知，本实用新型为一种高稳定的柔性透明导电复合膜，其电阻值具有良好的高温稳定性，且柔性、透明度好，广泛适用于触摸屏、EL光源、透明薄膜加热器、透明静电屏蔽、透明防霜雾等。
附图说明
图1是本实用新型的截面剖视结构。在图中1、3-锌铝氧化物(ZAO)膜层，2-铟锡氧化物(ITO)膜层，4-PET聚酯塑料膜。
具体实施方案
按照附图和上述结构的本实用新型产品，采用透明柔性基材PET聚酯塑料膜4，其厚度为175μm化物膜层1、3的厚度分别为300和100，铟锡氧化物膜层2厚度500。
