Method for measuring thermal weight loss temperature of organic photoelectric material based on vacuum state

The invention belongs to the technical field of detection, and discloses a method for measuring the thermal weight loss temperature of an organic photoelectric material based on a vacuum state. The method is carried out under the vacuum degree condition of 1-10Pa, a crucible and an organic photoelectric material to be detected are used in the method, and the volume of the organic photoelectric material to be detected does not exceed half of the volume of the crucible. According to the method, the temperature result of 0.5% of thermal weight loss of the finally tested organic photoelectric material is kept consistent with the sublimation temperature of the organic photoelectric material tested under the vacuum degree of 4.0 * 10 Pa in the prior art. Therefore, the accuracy of the thermal weight loss temperature of the organic photoelectric material measured under the test condition is high, and the vacuum degree requirement is far lower than that in the prior art, so that the measurement cost is greatly
