Abstract
Offshore wind turbines are subjected to harsh marine environment, which can cause detrimental problems to their integrity due to corrosion. Offshore wind energy is considered to play an important role on the net zero emissions by 2050, contributing to environmental protection, hence the long-term protection from corrosion of these offshore structures is of high importance. In this work the formation of microcapsules, loaded with corrosion inhibitor liquid is presented. More specifically the microcapsules consist of polystyrene shell and 3-octanoylthio-1-propyltriethoxysilane core. The formation of the microcapsules was achieved by testing different variables such as four agitation rates and three different emulsifiers. The experiments revealed that the optimum diameter size was achieved in agitation rates between 400 and 500 rpm and with sodium dodecylbenzene sulfonate (SDBS) as emulsifier. Agitation times were also tested. Hence, this work highlights the formation of microcapsules with self-healing properties, which can offer corrosion solution to offshore wind turbines when used as part of a coating system.
