Research on corrosion-resistant polymer coatings has attracted scientists in both academia and industry to prevent corrosion-related damage in modern industrial equipment and to extend the working life of industrial metallic surfaces. To achieve realistic applications, diverse methodologies have been designed to magnify the anticorrosion efficiency of these coatings. The current review describes the conventional and advanced methods utilized for the synthesis of corrosion-resistant polymer coatings. The main intent of this review article is to provide an overview of the design and preparation of anticorrosive polymer coatings with important examples. The promising anticorrosion applications of self-healing polymer coatings for metallic materials and alloys are highlighted. The advantage of a superhydrophobic surface to prevent the corrosion of the materials is discussed. A brief discussion over the anticorrosion mechanism of conducting polymer coatings is also provided. Finally, the current challenges and future perspectives to prolong the anticorrosion performance of these coatings are also addressed.

The denser and faster componented next‐generation electronic devices produce an increased amount of heat during operations. Thermal dissipation is critical to the performance, lifetime, and reliability of electronic devices. With emerging of new applications such as three‐dimensional chip stack architectures, flexible electronics, and light‐emitting diodes, thermal dissipation becomes a challenging problem. In this study, a new resole‐based epoxy monomer is designed. The novelty of the monomer is triepoxy functional soth upon curing (polymerization) the crosslink density is more. Composites of this epoxy with graphene functionalized with amine have been synthesized and characterized by thermal and mechanical methods. The thermal conductivity is increased to 0.6 W/mK by using graphene amine (12 wt%), which suggests that the composites can be useful for encapsulations. The composites are also useful as a coating material for corrosion protection on mild steel (MS). The electrochemical polarization studies on coated specimens showed that the composites are excellent coatings, which exhibited a very low corrosion rate of the order of 10−3–10−4 mm/year.

This article describes the synthesis of conducting hybrid polyurethanes from novel tetraaniline‐diol as Gly‐TAni (glycidol with TAni). A new diol Gly‐TAni has been synthesized in a simple process using tetraaniline (TAni) and glycidol via SN2 reaction in a single‐step process. The asymmetric diol (Gly‐TAni) and polyols (PTMEG and TMP) were reacted with isophorone diisocyanate at OH:NCO ratio of 1:1.2 to obtain ―NCO terminated hybrid conducting polyurethanes. These were subjected for curing under atmospheric moisture to obtain conducting polyurethane‐urea coatings. The conducting coatings showed considerable enhancement in thermal and mechanical stabilities. All these conducting coatings films showed excellent corrosion resistance (on mild steel electrode) with an increase in the percentage of Gly‐TANi (5 to 15 wt%). The films of these hybrid polyurethanes containing pendent tetraanilines showed good surface conductivity in the range of 3.69 × 10−4 to 2.21 × 10−3 S/cm. The electrochemical investigation showed 2 single electron oxidation and 2 single reductions reversibly, centred around tetraaniline segments present in the polymer.
