摘要：

Thermoelectric (TE) devices have one main disadvantage: short service lifetime. These devices undergo degradation by sublimation, oxidation, and reactions in corrosive environments. To prevent the degradation, we have applied two high temperature polymers (HTPs) as coatings for Bi2Te3-based TE materials. Sintering temperatures were from 250 degrees C to 400 degrees C. EDS and SEM results show that the coatings prevent the oxidation and sublimation of TE materials. We also shorten the curing cycle time and lower the energy costs. Electrical resistivity values show that Bi2Te3 materials can perform well up to 300 degrees C with our HTPs.
