Preparation of Polypyrrole-polyaniline/Graphene/Silica Composite Film and its Anti-corrosion Properties
In this paper,P(ANI/Py)/RGO/SiO2 composite films were prepared by electrochemistry,and we found a way to electrochemically prepare ternary composite films.At the same time,the corrosion resistance of P(ANI/Py)film and P(ANI/Py)/SiO2 film is compared.It is found that the ternary composite film obtained at 0.025 mo1/L aniline 0.075 mo1/L pyrrole has better corrosion resistance.The corrosion potential was-0.535 V and the corrosion current was 1.828×10-9 A·cm-2.
