Self-Healing Thin Films: Paving the Way for Smart, and Sustainable Corrosion Protection

  1. Abdulrahaman Mohammed Department of Scientific and Industrial Research, National Research Institute for Chemical Technology

Abstract

Corrosion is one of the serious problems that industries and infrastructures of every type face, ranked among such threats as huge economic losses and concerns to global safety. Recent developments in the area of self-healing thin films make them a really promising innovation for enhancing corrosion protection. This review considers the development, mechanisms, and applications of self-healing thin films. Detailed here are intrinsic and extrinsic self-healing strategies oriented toward chemical and physical mechanisms realizing autonomous repair. It covers in detail current fabrication methods, such as layer-by-layer assembly and sol-gel techniques, and surface enhancement and application methodologies like spraying and dip- coating. Case studies demonstrate the successful application of self-healing coatings in the marine and automotive industries, among others. The review further discusses performance evaluation techniques of corrosion resistance and self-healing efficacy, including standard and novel testing methods. While discussing the improvement in properties and functions of self-healing materials, a focus has been put on the development in nanotechnology and biotechnology. The discussion finally extends to future prospects and emerging trends and possible amalgamation of smart coatings with IoT for real-time monitoring. The review also addressed formulation, application, durability, environmental stability, and economic issues. It concludes with reflections on the transformative power of self-healing technologies in materials science and engineering and provides insights into commercialization and industrial adoption.
