Advances in Materials Science and Engineering has retracted the article titled “Structural and Electrical Properties of Graphene Oxide-Doped PVA/PVP Blend Nanocomposite Polymer Films” [1] due to figure duplication from the authors’ earlier work, which was not cited [2]. The experiments in which these images are said to represent are similar, but not the same: Figure 4(b) in [1], showing scanning electron microscopy of a polymer electrolyte film of PVP/PVA : GO with a ratio of 0.25 : 0.2 is a magnified, high-resolution version of Figure 4(b) in [2] showing a ratio of 0.4 : 0.2.
The authors also reused the images in Figures 4(a) and 4(c) [1] when they attempted to correct another article, which was also retracted due to figure issues [3].
The authors do not agree with the retraction.
