Summary Conductive polymer composites based on carbon materials are widely used in commercial applications. Herein, electrically conductive melamine‐formaldehyde (MF) resin was fabricated by incorporating various loadings of graphite nanosheets (GNS) via in‐situ polymerization followed by crosslinking at 165 °C. The effect of GNS loading on the electrical conductivity, interfacial properties and thermal stability of the composites is discussed. SEM fractogram confirm the uniform dispersion and toughening of MF upon GNS reinforcement. The electrical percolation was achieved at about 0.9 vol.% loading of GNS suggesting an aspect ratio for GNS between 130 and 240 depending on the model used.
