Abstract |
Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) is one of the most excellent conducting polymer as well as thermoelectric polymer due to good water solubility , flexibility, economic and commercial availability. Furthermore, carbon nanotube (CNT) is also one of the high conducting materials. In this paper, we present the characterization of PEDOT:PSS /CNT nanocomposite aerogels fabricated via an easy and reproducible freeze–drying method adding crosslinking agents, such as glycidoxypropyl trimethoxysilane (GOPS). For fabrication of the aerogel, freeze-drying method is used from dispersed PEDOT:PSS/CNT solution. After crosslinking process at 140℃, the nanocomposite aerogels are successfully formed. These nanocomposite aerogels show better electrical conductivity and thermoelectric effect than those of pristine PEDOT:PSS aerogels due to embedding CNTs into PEDOT:PSS matrix. Moreover, by combining PEDOT:PSS and nanofibrillated cellulose (NFC), mechanical property of aerogels is enhanced. Therefore, this work demonstrates that the electrical property of PEDOT:PSS aerogels can be improved by adding CNT with facile method. |
