Abstract
The silica/polypyrrole nanocomposite (SiO2/PPy) material has widely been used in the World and Vietnam as well. Here, the material has been synthesized using in situ micro-emulsion method for application in organic coating to protect against corrosion for CT3 steel. The influence of the solvent on the characteristics and properties of SiO2/PPy nanocpmpozite has been studied. Our research results show that synthetic solvents do not much affect the structure and morphology of the synthesized materials. Nanocompozite SiO2/PPy-W synthesized in a water solvent has the highest conductivity (σ = 0.19 S.cm-1), which is higher than the electrical conductivity of SiO2/PPy-EW and SiO2/PPy-E synthesized in alcohol/water and alcohol solvent (0.14 S.cm-1 and 0.11 S.cm-1), respectively.References
