Detection Methods and Standards for Ozone Aging Tests on Thin Films

This paper mainly introduces the aging test method for film materials in an ozone environment. The principle is to accelerate the oxidation of films using ozone to evaluate their durability. It lists domestic and international standards such as ISO, ASTM, and GB/T, and specifies that the test equipment must precisely control ozone concentration, temperature, and humidity. Samples need to be cut to specified dimensions and pre-treated. The test steps include applying tension, exposing to ozone, and observing cracks. Evaluation indicators include the time of crack appearance, crack density, and retention rate of mechanical properties. It also analyzes influencing factors such as concentration and temperature, as well as solutions to common issues.
