Enhanced electrochemical and bioactivity performance of porous magnesium oxide@magnesium composites with transparent hydrogenated C36 dimer fatty acidOA
Structural microdefects on inorganic layers grown via soft plasma discharge can aggravate corrosion in numerous settings.Therefore,advanced surface treatments is required emergently to develop superior corrosion-resistant coating while it still remains challenging to incorporate dual functions such as anticorrosion and antibacterial attributes simultaneously for versatile applications.To this end,this study presents a rapid approach to treat structural pores and cracks with diverse dimensions and sizes in inorganic layers through the self-assembly of hydrogenated C36 dimer fatty acid(DFA;C_(36)H_(68)O_(4))on defect sites.Microstructural analysis an d first-principles calculations revealed that physical an d chemical interaction s between DFA and the inorganic layer significantly improved the performance and accuracy of the defect treatmen t.The resulting DFA-inorganic hybrid material demonstrated superior corrosion resistance an d antibacterial activity due to the hydroxyl group''s electrondon ating properties,which considerably enhan ced the adsorption of the transparen t hydrogenated DFA layer onto the inorganic layer.Additionally,the anticorrosive performance was driven by chemical adsorption through three Mg-O bonds.
