Abstract
Expression of concern for ‘High performance flexible supercapacitors based on secondary doped PEDOT–PSS–graphene nanocomposite films for large area solid state devices’ by Syed Khasim et al., RSC Adv., 2020, 10, 10526–10539, https://doi.org/10.1039/D0RA01116A.
RSC Advances is publishing this expression of concern in order to alert our readers that we are presently unsure of the reliability of the data reported in Fig. 7 of this article. In addition, two images presented in Fig. 2 appear to have been reproduced from previous publications by different authors without appropriate acknowledgement.
An investigation is underway, and an expression of concern will continue to be associated with the article until a final outcome is reached.
