N2 - The durability and functionality of many metallic structures are
seriously threatened by corrosion, which makes the development of
anticorrosive coatings imperative. This state-of-the-art survey explores
the recent developments in the field of anticorrosive organic coatings
modulated by innovations involving nano/microcontainers with porous
matrices. The integration of these cutting-edge delivery systems seeks
to improve the protective properties of coatings by enabling controlled
release, extended durability, targeted application of corrosion
inhibitors, and can be co-constructed to achieve defect filling
by polymeric materials. The major highlight of this review is an
in-depth analysis of the functionalities provided by porous
nano/microcontainers in the active protection and self-healing of
anticorrosive coatings, including their performance evaluation. In one
case, after 20 days of immersion in 0.1 M NaCl, a scratched coating
containing mesoporous silica nanoparticles loaded with an inhibitor
benzotriazole and shelled with polydopamine (MSNs-BTA@PDA) exhibited
coating restoration indicated by a sustained corrosion resistance rise
over an extended period monitored by impedance values at 0.01 Hz
frequency, rising from 8.3 × 104 to 7.0 × 105 Ω cm2,
a trend assigned to active protection by the release of inhibitors and
self-healing capabilities. Additionally, some functions related to
anti-fouling and heat preservation by nano/microcontainers are
highlighted. Based on the literature survey, some desirable properties,
current challenges, and prospects of anticorrosive coatings doped with
nano/microcontainers have been summarized. The knowledge gained from
this survey will shape future research directions and applications in a
variety of industrial areas, in addition to advancing smart corrosion
prevention technology.
