Congratulations to Dr. Zhang Mengmeng for receiving the paper by Carbon 

    In this work, we demonstrated a general approach to evaluate the level of space filling of CNT interfacial surface area quantitatively using fractal dimension calculation and clarified the relationship with the composite electrical conductivity and mechanical strength. In addition, we proposed a map to increase the level of space filling of interfacial surface area as estimated by the increased fractal dimension through controlling various dispersion conditions during CNTs dispersion, which is of great significance to the fabrication of CNT composites.
