Abstract
The interfacial interaction between the two phases in polybenzoxazine/SiO2 nanocomposite coatings was controlled through modifying surface functionalities of SiO2 nanoparticles (SNP). SNPs with methyl, epoxide, and benzoxazine groups on the surface were prepared in this work, which was characterized by FTIR, TGA, and elemental analysis. The strong chemical bonding between nanoparticles and polybenzoxazine was obtained because of the reaction between epoxide groups or benzoxazine groups and benzoxazine molecular during the curing process. Both surface properties and corrosion resistance of composite coatings were fully investigated with the assistance of SEM, EDS, water contact angle measurement, and EIS technique. SNP incorporation could reduce porosity of the coatings so significant that all SNP loading nanocomposite coatings exhibited excellent corrosion resistance with a charge transfer resistance of over 1 GΩ cm2 during 31 days’ immersion in a 3.5 wt % NaCl aqueous solution, which was 3 orders of magn...
