Introduction

As capacitive touch screens are increasingly used, from smart education and smart conferences to smart travel, smart healthcare and government affairs, In the fields of electronics, the application demand of capacitive touch screen is increasing. Nano silver wire transparent conductive film has high light transmittance, low square resistance and good flexibility.

Characteristics, in the application of flexible touch screen and rigid touch screen sensing layer, it has unique advantages.

Since the nano silver wire transparent conductive film material is often exposed to solar radiation or solar radiation behind glass during use, the solar Radiation, temperature, humidity and other climatic factors have a significant impact on material performance. Exposure in laboratory equipment is more likely to occur in the natural environment.

In order to more quickly measure the effects of solar radiation, temperature, and humidity on material properties, nanosilver wires are often used to penetrate the Test method for evaluating the light resistance of bright conductive films by exposing them to a xenon lamp (an artificial light source that simulates the spectrum of sunlight passing through window glass).

It can guide the evaluation, screening, research and development and improvement of new materials.
