Thermoelectric Enhancement of Polyaniline Grafting from Graphene Oxide

Year: 2016

Type: article

Abstract: In this study, a PANI covalently grafted GO (GO-PANI) was obtained through amide reaction and a PANI covered GO (GO/PANI) was prepared via in-situ polymerization. The better thermoelectric properties were achieved in GO-PANI compared with GO/PANI under the same situation, i.e., the equal mass ratio of GO and PANI as well as the oxidative degree of polymerization reaction. Furthermore, polyaniline grafted from the reduced graphene [R(GO-PANI)] was prepared by reducing the above GO-PANI using hydrazine hydrate and the improved power factor as high as 3.6 × 10-8 W m-1 K-2 was attained at 341 K.
