| مستخلص: |
Polymer materials are frequently used in vacuum systems despite their relatively high outgassing rates, with water being the primary component of this outgassing. In this paper, we propose a novel modeling method for predicting water outgassing from polymers. This model incorporates both the adsorption and desorption dynamics of water molecules on the material's surface, offering a more comprehensive understanding of outgassing behavior. Experimental measurements were conducted by throughput method on two polymer materials commonly used in satellite systems to validate the proposed model, specifically carbon fiber-polymeric composite materials and polyimide cable materials. A temperature-variable simulation was also conducted to verify the applicability of the model. The results demonstrate the accuracy and applicability of the method, providing guidance for optimizing material selection and vacuum system performance in different applications.
