Polyaniline (PANI) particles were prepared by using block copolymer polystyrene-b-poly(N-isopropylacrylamide) [PS111-b-PNIPAMx(x=30,60,84)] as template.The size and size distribution of PANI particles were effectively controlled by adjusting the hydrophilic segment length of the template.Structural characterization was done by FT-IR and UV-Vis.The morphology and electrochemical properties of the products were characterized by granularity test,cyclic voltammetry,chronopotentiometry and electrochemical impedance measurements.The results shown that the particle size of PANI was below 145nm and the distribution index was small,indicating that the particle size is uniform.When the hydrophilic segment length of the template was 84,the electrochemical performance of PANI was the best,and the discharge specific capacitance can reach 1117.67F/g at current density of 1A/g.
