“…10(d). In fact, the increase in inhibitor concentration in an electrolyte is often described by an exponential function of time [52][53][54][55]: own the same release exponent n of around 0.5, which means the release process is controlled by Fickian diffusion [56]. In addition, we can also see that k increased with SiO 2 @BTA pigment concentration, due to the variation in initial concentration of BTA in the materials.…”

“…In order to tailor the micro-nano-containers, some features need to be guaranteed, such as (i) chemical and mechanical stability, (ii) chemical compatibility with the coating matrix, (iii) effective loading capacity, (iv) to limit accidental inhibitor release, (v) corrosion selectivity, and (vi) on-demand release of the hosted inhibitor [24]. In such a context, a really promising approach that in the last year was acquiring significant relevance and that allows a potentially reliable coating design, is the use of zeolite as filler and micro-container for inhibitor species encapsulation [25] favoring self-healing mechanisms in this class of new smart coatings [26,27]. More recently, Calabrese in [25] assessed the effectiveness and affordability to corrosion protection of pure zeolite coating, highlighting its promising capabilities.…”

Research activity concerning nanoporous zeolites has grown considerably in recent decades. The structural porosity of zeolites provides versatile functional properties such as molecular selectivity, ion and molecule storage capacity, high surface area, and pore volume which combined with excellent thermal and chemical stability can extend its application fields in several industrial sectors. In such a context, anti-corrosion zeolite coatings are an emerging technology able to offer a reliable high performing and environmental friendly alternative to conventional chromate-based protective coatings. In this article, a focused overview on anti-corrosion performances of sol-gel composite zeolite coatings is provided. The topic of this review is addressed to assess the barrier and self-healing properties of composite zeolite coating. Based on results available in the literature, a property–structure relationship of this class of composites is proposed summarizing, furthermore, the competing anti-corrosion active and passive protective mechanisms involved during coating degradation. Eventually, a brief summary and a future trend evaluation is also reported.

Mini-Review of Self-Healing Mechanism and Formulation Optimization of Polyurea Coating

Self-healing polymers are categorized as smart materials that are capable of surface protection and prevention of structural failure. Polyurethane/polyurea, as one of the representative coatings, has also attracted attention for industrial applications. Compared with polyurethane, polyurea coating, with a similar formation process, provides higher tensile strength and requires shorter curing time. In this paper, extrinsic and intrinsic mechanisms are reviewed to address the efficiency of the self-healing process. Moreover, formulation optimization and strategic improvement to ensure self-healing within a shorter period of time with acceptable recovery of mechanical strength are also discussed. The choice and ratio of diisocyanates, as well as the choice of chain extender, are believed to have a crucial effect on the acceleration of the self-healing process and enhance self-healing efficiency during the preparation of polyurea coatings.
