DOI: 10.1007/s10971-020-05315-x
Abstract: Hybrid organic–inorganic sol–gel based coatings are of increasing interest nowadays as conversion coating replacements due to their promising performance. They provide good barrier properties; however, they lack active corrosion protection. Lanthanum 4-hydroxy cinnamate [La(4-OHCin)3] was… read more here.
