Abstract

Polyaniline capsules with superhydrophobic and hollow spherical morphology were synthesized via emulsion polymerization method with different amount of surfactant sodium dodecylbenzenesulfonate (SDBS) as modification agent, in order to solve the problems of poor compatibility of polyaniline (PANI) with resin, and the lack of tight bonding interface in organic coatings. The results show that the morphologies of the prepared products with different surfactant additions are all hollow spherical, and their water contact angle can be increased from 67° to 152°, while it may be speculated that capsules with the inherent micro/nano cavity structure may be used to encapsulate corrosion inhibitors and other substances. Next, epoxy resin coatings without and with superhydrophobic capsules as coating fillers were prepared, and then comparatively tested in 3.5%NaCl solution for 14 d. It follows that the low-frequency impedance modulus value of the coatings with superhydrophobic capsules reaches c.a. 2.69×10¹⁰, in other word, the epoxy resin coatings with hydrophilic polyaniline as filler exhibit excellent corrosion resistance more than one order of magnitude superior to the blank ones. Which may be ascribed to that the super-hydrophobicity of the powder increases the diffusion resistance of the corrosive medium in the coating. At the same time, due to the doping of long-chain alkyl groups, the compatibility of polyaniline powder in epoxy resin is improved, therefore, the coating corrosion resistance is enhanced.

Key words: polyaniline superhydrophobic hollow sphere organic coating
