  • Citations are the number of other articles citing this article, calculated by Crossref and updated daily
  • The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online
  • The composites are synthesized under different mass ratios, using graphite as start material with two sizes: 12 500 and 500 mesh
  • The result shows that the morphology of the prepared composites is influenced dramatically by the different mass ratios
  • The improved capacitance retention of 73% and 64% after 500 cycles is obtained for the mass ratios 1:23 and 1:19 compared to PANI of 20%
  • This study is of significance for developing new doped PANI materials for supercapacitors
