摘　　要：通过简单的丝网印花,将磷酸(PA)、微晶纤维素(MCC)、碳纳米管(CNT)组成的分散液整理到棉织物表面,制备了表面负载CNT的热电(TE)织物。通过光学显微镜(OM)证明了PA-MCC对CNT的良好分散性;采用扫描电子显微镜(SEM)观察到织物表面MCC-CNT覆盖层的形成;测得TE织物的塞贝克系数约为24μV/K,并且其值随串联TE单元数目的增加而增加,验证了TE基本单元的可集成性;通过测试不同弯曲次数下的塞贝克系数,证明织物热电性能的耐久性;演示了TE织物可用于人体热量的收集。Through simple screen printing, thermoelectric(TE) fabric coated with carbon nanotubes(CNT) is prepared by treating the cotton fabric with the dispersion composed of phosphoric acid(PA), microcrystalline cellulose(MCC) and CNT. The dispersion of PA-MCC to CNT is demonstrated by optical microscopy(OM). Scanning electron microscope(SEM) is used to observe the formation of MCC-CNT coating on the fabric surface.The Seebeck coefficient of TE fabric is tested to be about 24 μV/K, and its value increases with the increase of the number of TE units in series, which verifies the integration ability of TE basic units. By testing the Seebeck coefficient under different bending times, the durability of the thermoelectric properties of the fabric is proved.It is demonstrated that TE fabric can be used to collect heat from human body.
