Title:
TRANSPARENT CONDUCTIVE PIEZOELECTRIC FILM AND TOUCH PANEL
Document Type and Number:
WIPO Patent Application WO/2022/091829
Kind Code:
A1
Abstract:
The present invention provides a transparent conductive piezoelectric film having a transparent piezoelectric film made of a fluororesin, wherein variations in surface resistance values in high temperature or high humidity environments are suppressed. A transparent conductive piezoelectric film (10) is constituted by stacking, in the following order, a transparent piezoelectric film (1) made of a fluororesin, a transparent coating layer (2), and a transparent electrode (3). The total thickness of the coating layer (2) is 0.6-4.5 μm. The ratio of the resistance value of the transparent conductive film (10) after standing for a specific period of time in a specific high temperature environment with respect to before the standing period is 1.30 or less.
