Special Issue Information

Dear Colleagues,

Polymer coatings have shown tremendous potential as functional coatings in applications such as supercapacitors, wastewater treatment, and corrosion prevention. These coatings offer adjustable properties, including electrical conductivity, chemical resistance, and mechanical flexibility. In supercapacitor applications, polymer coatings enhance energy storage performance by improving the electrode–electrolyte interface, leading to increased charge storage capacity and electrochemical stability. Researchers have achieved significant improvements by optimizing the polymer composition and structure. Polymer coatings have also demonstrated promise in wastewater treatment by acting as selective barriers for efficient separation and removal of contaminants. Tailoring the coatings allows selective adsorption of specific pollutants, such as heavy metals, organic compounds, or microorganisms, resulting in improved water quality and reduced environmental impact. For corrosion prevention, polymer coatings form protective barriers on metal surfaces, preventing the penetration of corrosive agents such as moisture and chemicals. Self-healing properties can be incorporated, minimizing damage and extending the lifespan of coated structures. The development of polymer materials as functional coatings offers exciting opportunities in diverse applications. Further research and advancements in polymer synthesis and coating techniques are expected to drive progress in energy storage, water treatment, and corrosion resistance, leading to more efficient devices, improved systems, and enhanced protection in various industries.

The presence of heavy metals with high acute toxicity in wastewater poses a substantial risk to both the environment and human health. To address this issue, we developed a nanocomposite of alginate-encapsulated polypyrrole (PPy) decorated with α-Fe2O3 nanoparticles (Alg@Mag/PPy NCs), fabricated for the removal of mercury(II) from synthetic wastewater. In the adsorption experiments, various parameters were examined to identify the ideal conditions. These parameters included temperature (ranging from 298 to 323 K), initial pH levels (ranging from two to nine), interaction time, amount of adsorbent (from 8 to 80 mg/40 mL), and initial concentrations (from 10 to 200 mg/L). The results of these studies demonstrated that the removal efficiency of mercury(II) was obtained to be 95.58% at the optimum pH of 7 and a temperature of 303 K. The analysis of adsorption kinetics demonstrated that the removal of mercury(II) adhered closely to the pseudo-second-order model. Additionally, it displayed a three-stage intraparticle diffusion model throughout the entire adsorption process. The Langmuir model most accurately represented equilibrium data. The Alg@Mag/PPy NCs exhibited an estimated maximum adsorption capacity of 213.72 mg/g at 303 K, surpassing the capacities of most of the other polymer-based adsorbents previously reported. The thermodynamic analysis indicates that the removal of mercury(II) from the Alg@Mag/PPy NCs was endothermic and spontaneous in nature. In summary, this study suggests that Alg@Mag/PPy NCs could serve as a promising choice for confiscating toxic heavy metal ions from wastewater through adsorption. Full article
