Abstract: Among many conductive polymers, polyaniline, as a commonly used functional polymer,
has many advantages. By compounding polyaniline with nano-silica particles, the prepared compound
material can be applied to anti-corrosion coatings, anti-fouling coatings, electronic components and so on.
The structure and properties of the composites are affected by the synthesis method, reaction conditions
and doping acid species. In this paper, three inorganic acid-doped polyaniline composite silica products
were prepared under the same reaction conditions by chemical oxidative polymerization, and their
characterization tests were carried out. The results show that phosphoric acid as the doping acid has the
highest yield, but the lowest conductivity. Compounding an appropriate amount of silica can effectively
increase the yield and conductivity of the sample. The samples doped with hydrochloric acid and sulfuric
acid have similar granular surface morphologies, while the phosphoric acid samples are lamellar. The
composites prepared by the three protonic acids have good crystallinity.
Key words: polyaniline; nano-silica sol; composite material; acid doping
