GB/T 44210-2024 in English

1. Standard Overview

GB/T 44210-2024 is mainly aimed at the accelerated aging test method of nanosilver wire transparent conductive film under xenon lamp. This standard is applicable to the accelerated aging performance test of transparent conductive film based on nanosilver wire using xenon lamp, and can also be used as a reference for the accelerated aging performance test of transparent conductive film based on other nanomaterials.

2. Background of Standard Formulation

With the widespread application of capacitive touch display screens in many fields, nanosilver wire transparent conductive film has attracted much attention due to its high transmittance, low square resistance and good flexibility. However, this material is often exposed to solar radiation or solar radiation behind glass during use, so it is crucial to determine the impact of these environmental factors on material performance.

In order to determine the light resistance more quickly, the accelerated aging test using a xenon lamp to simulate the sunlight spectrum through window glass has become an important method for evaluating the light resistance of materials.

3. Analysis of Technology Evolution

The light resistance test technology of nano silver wire transparent conductive film has evolved from natural environment exposure test to laboratory simulation accelerated test. Xenon lamp accelerated aging test greatly shortens the test cycle and improves evaluation efficiency by simulating solar radiation, temperature and humidity.

5. Implementation suggestions

Sample preparation:Ensure that the sample structure meets the standard requirements, and pay special attention to the treatment of the conductive and non-conductive surfaces to avoid affecting the test results.

Test condition setting:Select appropriate irradiance, temperature and humidity parameters according to material properties and application environment. It is recommended to conduct a preliminary experiment before the formal test to ensure that the equipment parameters are stable.

Data processing and analysis:Strictly calculate the transmittance change rate, b* value change rate and resistance change rate according to the standard formula, and verify the repeatability and reproducibility of the results.
