Abstract: 

In this study the healing performance of micro-cracks by microcapsules containing linseed oil in the coating of polyaniline as conducting polymer were investigated. The In situ polymerization in the urea - formaldehyde resin was done to produce linseed oil capsules. The synthesized capsules were studied by Scanning Electron Microscope and contents were determined 75% of their oil. The (FTIR) test was performed to verify the success of being microcapsule. The process of Polyaniline coating was performed by using the electrochemical galvanostatic method in 0.7, 0.9, 1, 2 and 3 A/dm2 current densities. The performance of corrosion resistance of the composite coating containing microcapsules was studied by potentiodynamic polarization test in the 3.5 percent solution and immersion in the 5 percent sodium chloride corrosive solution. The results showed that sample coated with a current density of 1 A/dm2 composite with 0.01 weight of microcapsules had very good self-healing and corrosion resistance properties and Efficiency of 95% was determined to protect it.
