摘要
本研究开发了利用磷酸锌水泥和碱性硅酸钠水溶液作为黏合剂的丝网印刷形成n型和p型热元件腿的技术,研究了厚膜的热电性能.以碱性硅酸钠水溶液为黏合剂,利用基于Bi2Te3-Sb2Te3(p型)和Bi2Te3-Bi2Se3(n型)的悬浮液的丝网印刷结果,制备了柔性热电发电机(TEG)的原型.开发的原型包括6对由铜线连接的n型和p型腿,和一个硅胶基质被用作柔性底座.对样机的研究表明,在室温(298 K)下,柔性厚膜TEG在温差∆T=2.5 K和10.0 K下的输出电压分别为0.8 mV和14.8 mV.
Abstract
In this work,a method for the formation of legs of n-and p-type thermoelements by screen printing using zinc phosphate cement and aqueous alkaline sodium silicate solution as binders was developed.Thermoelectric properties of thick films were investigated.A prototype of a flexible thermoelectric generator(TEG)was developed and fabricated using the results obtained by the screen printing method from suspensions based on Bi2Te3-Sb2Te3(p-type)and Bi2Te3-Bi2Se3(n-type)with an aqueous alkaline sodium silicate solution as binder.The developed prototype includes 6 pairs of n-and p-type legs connected by copper wires,and a silicone matrix was used as a flexible base.The prototype showed that at room temperature(298 K)the output voltages of the flexible thick film TEG at temperature differences ∆T=2.5 and 10.0 K are 0.8 and 14.8 mV,respectively.
