Preparation and discussion of bacterial cellulose/polypyrrole conductive composite film
Supercapacitor is a new type of energy storage device,consisting of carrier,polymer conductive material,oxidant,etc.In terms of carrier,bacterial cellulose film with good toughness and excellent porosity has been used as a substrate material.In this study,Bacillus glucoaceticus was selected to grow in specific medium to form bacterial cellulose material film,extracted and processed with polypyrrole(PPy)and oxidant in situ polymerization,FeCl3 was used as oxidant The membrane was then extracted and processed with polypyrrole(PPy)and oxidant in situ,and FeCl3 was used as the oxidant to polymerise and attach different concentrations of pyrrole to its surface to form a supercapacitor.The results show that the porosity and conductivity are not proportional to each other,with the maximum conductivity within 25％-30％porosity,the maximum porosity of 60.05％for 0.01 mol/L concentration polypyrrole but the minimum conductivity(1×10-6 S/m),and the maximum conductivity obtained for 0.06 mol/L concentration polypyrrole with 23.04％porosity(2.6×10-1S/m).
