An environmental friendly self-healing coating with Silane/Ce-ZSM-5 zeolite structure for corrosion protection of aluminum alloy

Self-healing materials for potential use in textile and clothing applications

“…Fiber-reinforced polymer composites with metal alloys or fiber-reinforced ceramic composites with integrated self-healing techniques are used in components such as aircraft fuselages and engines in the aerospace industry or in coatings [54][55][56]. Several problems in the aerospace industry can be solved by the mechanical, physical and chemical properties of self-regenerating systems.…”

Lanthanides: The Key to Durable and Sustainable Corrosion Protection

“…Cerium (Ce), second element of Ln series, is abundantly present in nature as the Earth’s crust contains 0.0046 wt % of Ce, while its quantity in seawater is 1.5 parts per trillion (ppt). The small energy difference between the inner 4f electron and the outer valence electrons allows cerium to have two stable valence states, 3+ or Ce­(III) and 4+ or Ce­(IV). − The crystallite size and morphology of cerium-based oxides are directly related to the formation/diffusion/removal of oxygen vacancies, enabling a Ce redox reaction between Ce 3+ and Ce 4+ species, which is perhaps one of the most important factors in making Ce oxide a promising material for multifunctional coatings. − The initial startup of Ce as an anticorrosive coating started when Al alloys were homogeneously coated in minimal time, with cerium-rich deposits. , …”

Coatings made from chemicals: A review

“…Formation of hybrid coating and hosting nanoparticle as nano‐reservoirs on the overcoat to activate the self‐healing potential of the coatings and enhancement of anticorrosion performance are the real upcoming trends of tomorrow. [ 159 ] In addition, recycling of waste into production of sustainable coating is really a bigger challenge in the near future.…”
