Preparation of MXene/PPy@TOCNF Hybird Film and Its Electrochemical Performance
MXene/PPy@TOCNF(MPT)hybrid film was prepared by in-situ polymerization of PPy on the surface of TOCNFs(cellulose nanofibers)combined with MXene under vacuum filtration.The structure and morphology of the(MPT)mixed film were analyzed by TEM,SEM,XRD,FT-IR.The electrochemical workstation was used to investigate the effect of the content of polypyrrole@cellulose nanofibers on the electrochemical performance of the MXene film.The results showed that the addition of PPy@TOCNF improved the electrochemical performance of the hybrid film.At a current density of 1 A·g-1,the specific capacitance of MPT-20%film was 415.6 F·g-1,which was much higher than that of MXene(284.5 F·g-1).
