The Effect of Complex Emulsifier on the Structure of Tung Oil and Phenolic Amides Containing Microcapsules and Its Anti-Fouling and Anti-Corrosion Performances

In this study, the urea-formaldehyde (UF)-tung oil solution of phenolic amide (PA) microcapsules to realize anti-fouling and anti-corrosion integration was synthesized by in situ polymerization method. The compounds structures were optimized investigating six kinds different emulsifiers. results showed that high-core-content narrow-particle-size-distribution could be with sodium dodecyl benzene sulfonate (SDBS)/polyvinyl alcohol (PVA), core content 75 wt% at microcapsule sizes from 24.07 71.33 µm. self-healing coatings when coating exceeded 10 wt%, healing agent released scratched surface cover naked metal effectively, which pass a 7 day neutral salt spray test without rust area. A sufficient dose can provided prevent diatoms mussels adhering. present work shows complex emulsifier better control particle size distribution microstructure microcapsules, admixture into resin epoxy excellent functions.
