Bio-based During a recent study, a robust coating with enhanced corrosion resistant and weathering resistant properties was developed by incorporating novel UV resistant fillers into epoxy matrix. Tea polyphenol (TP) functioned as the free radical scavenger, which was encapsulated into mesoporous silica nanoparticles with UV absorption ability (MSN-TP) to obtain the UV resistant filler. With the incorporation of 2 wt % MSN-TP fillers in the epoxy matrix, the uniform distribution of MSN-TP nanoparticles could block the penetration of corrosive media and hence strengthening the barrier property of the coating.
