1. An anticorrosive-coated substrate comprising:
a first cured liquid layer applied to the substrate, the first cured liquid layer having a thickness of at least about 100 micrometers, wherein the first cured layer consists of:
at least one polymer;
quasi-one-dimensional particles, wherein the quasi-one-dimensional particles are carbon nanotubes;
sacrificial metal particles;
at least one thixotropic agent, wherein the at least one thixotropic agent is chosen from the group consisting of diamines, dithiols, amino thiols, carboxylic anhydrides, diphenols, and Mannich curing agents; and
a solvent;
a second cured liquid layer having a thickness of at least 100 micrometers on top of the first cured liquid layer, wherein a percolation threshold of the quasi-one-dimensional particles is reached, wherein the first cured liquid layer and the second cured liquid layer were cured simultaneously, wherein the second cured layer consists of:
at least one polymer;
sacrificial metal particles;
at least one thixotropic agent, wherein the at least one thixotropic agent is chosen from the group consisting of diamines, dithiols, amino thiols, carboxylic anhydrides, diphenols, and Mannich curing agents; and
a solvent.
