Preparation of “Green” Microcapsules for Corrosion Protection: Linseed Oil Encapsulated PF Microcapsules

Abstract:

This work aimed to prepare linseed oil encapsulated phenol formaldehyde microcapsules for self-repairing coating in corrosion prevention applications. This coating not only extends service life of the underlying metal which, in turn, prolongs the availability of natural resource but also be an environmental-friendly coating. The microcapsules were prepared through oil-in-water emulsion (O/W) at operating temperature of 65°C. Amount of phenol and formaldehyde were varied at weight (grams) ratios of 3.76:6.49, 4.70:8.10 and 5.64:9.73. Microcapsules obtained at agitation rates of 250 and 600 rpm were in diameter ranges of 200-1000 μm and 25-550 μm, respectively. Amount of phenol and formaldehyde as well as agitation rate were found to correlate with oil storage capability. The larger the amount of phenol and formaldehyde, the less oil leaking presented. In case of agitation rate, differences in agitation rate produced different surface morphologies. At low agitation rate, microcapsules had rough surface but less oil leaking. As a result of oil leaking, agglomeration of microcapsules was observed.
