Claim 0:
1. A gradient-responsive corrosion-resistant coating comprising:
(a) a first layer comprising a transition metal oxide and mobile cations, wherein said transition metal oxide is ionically conductive for said mobile cations;
(b) a second layer comprising a biphasic polymer, wherein said biphasic polymer contains ionic groups, wherein said biphasic polymer comprises a discrete phase and a continuous transport phase with an average length scale of phase separation between said discrete phase and said continuous transport phase, wherein said continuous transport phase is capable of delivering oligomers in response to corrosion byproducts, and wherein said oligomers are ionically crosslinkable with metal cations; and
(c) optionally, a sealing layer disposed on said second layer.
