Here, we studied the charge-carrier modulation of single-walled carbon nanotubes (SWCNTs) via poly(vinyl acetate) (PVAc) doping and dedoping under ultraviolet (UV) light irradiation with the aim of pairing several p- and n-type SWCNTs as thermoelectric (TE) elements. The Seebeck coefficient of the SWCNTs was first made negative by doping with PVAc and then made positive again through UV-induced PVAc dedoping. A possible TE module configuration and the process for its fabrication are proposed, wherein prints and photopatterns can be obtained without the use of additional electrodes. Our findings enable the fabrication of fine TE modules using simple materials and techniques.

通过聚乙酸乙烯酯掺杂和去掺杂为热电发生器对喷墨印刷碳纳米管进行光诱导的电荷载流子调制
在这里,我们研究了在紫外线(UV)照射下通过聚乙酸乙烯酯(PVAc)掺杂和去掺杂对单壁碳纳米管(SWCNT)的电荷载流子调制,目的是将多个p型和n型SWCNT配对作为热电(TE)元件。首先通过掺杂PVAc使SWCNT的塞贝克系数为负,然后通过UV诱导的PVAc去掺杂使SWCNT的塞贝克系数再次为正。提出了可能的TE模块构造及其制造方法,其中无需使用额外的电极就可以获得印刷品和光图案。我们的发现使得能够使用简单的材料和技术来制造精细的TE模块。
