无机-聚合物复合材料已成为通过印刷技术加工的有前途的材料，因为它们的独特性质允许以降低的制造成本制造柔性可穿戴电子产品。在目前的工作中，组装一个灵活的微型热电发电机的无机聚合物材料的基础上，提出了一个完整的方法过程。使用的微粒通过自上而下的方法制备，从先前通过固态反应制备的材料开始，然后通过使用球磨按比例缩小。已经发现，必须用HCl进行化学处理以还原微粒表面上存在的Bi 2 O 3，这导致功率因数（PF）为2.29 μ W K-2 m（-1），这是未处理样品的两倍。基于Bi 2 Te 3微粒的柔性无机-有机热电厚膜的制备（
Inorganic-polymer composites have become promising materials to be processed by printing technologies because of their unique properties that allow the fabrication of flexible wearable electronics at reduced manufacturing costs. In the present work, a complete methodological process of assembling a flexible microthermoelectric generator based on inorganic-polymer materials is presented. The used microparticles were prepared by a top-down approach beginning with a previously prepared material by solid-state reaction and later scaled down through the use of ball milling. It was found that the necessity to proceed with a chemical treatment with HCl to reduce Bi2O3 present on the surface of the microparticle leads to a power factor (PF) of 2.29 mu W K-2 m(-1), which is two times higher than that of the untreated sample. On the fabrication of flexible inorganic-organic thermoelectric thick films based on Bi2Te3 microparticles (
