In recent years, carbon quantum dots (CQDs) have been extensively investigated in many fields because of their incomparable and unique properties. However, the application CQDs electrochemical field meets a big challenge due to low specific capacitance. It is very important improve performance CQDs. this study, facile synthesis method was developed synthesize CQD@PANI nanoparticles. The nanoparticles were prepared via precise quantitative adsorption polymerization method. TEM results showed that PANI shell thickness could be adjusted by controlling additive amount aniline. Cyclic voltammetry galvanostatic charge/discharge properties significantly improved coating PANI.
