Poly(dimethyl siloxane)anti-corrosion coating with wide pH-responsive and self-healing performance based on core-shell nanofiber containers
文献摘要：
In this research,core-shell electrospun fibers loaded with the shell of cellulose acetate and the core of oleic acid and alkyd varnish resin were synthesized and used within poly(dimethyl siloxane)(PDMS)to prepare self-healing and pH-responsive coatings for a steel substrate.The morphology of the electrospun fibers was characterized by scanning electron microscopy,transmission electron microscopy and confocal fluorescence microscopy.Thermo gravimetric analysis and Fourier transform infrared spectroscopy re-vealed that the self-healing agents were loaded successfully with a loading rate of 2.9％.The properties of the fiber-PDMS composite coating were characterized by water contact angle measurements,mechanical tests,electrochemical impedance spectroscopy,and scanning Kelvin probe.Results show that the max-imum self-healing efficiencies of the fiber-PDMS coating in alkaline and acidic solution are 95.96％and 97.04％,respectively.The composition of the self-healing agents at the damaged part of the coating was verified by an infrared mapping test and using an energy dispersive spectrometer.In addition,the sand-paper abrasion test shows the hydrophobic effect of fiber-PDMS coating remains above 88.2％and de-creases slightly through the addition of abrasion cycles.This research can pave the way for the industrial applications of pH-responsive self-healing coatings.
