Special Issue Information

Dear Colleagues,

This Special Issue on "Advanced Polymer Nanocomposites: Pioneering Innovations in Energy Storage and Environmental Applications" explores the emerging role of advanced polymeric materials in both the energy and environmental sectors. It highlights the development of polymer nanocomposites that enhance energy storage systems, such as batteries and supercapacitors, by improving charge storage and stability. Moreover, this Special Issue underscores the pivotal role of these materials in environmental solutions, particularly in wastewater treatment, where innovative polymeric materials are employed for adsorption, filtration, and catalysis. It invites contributions on cutting-edge polymer synthesis, functionalization methods, and the development of polymer-based membranes, adsorbents, and photocatalysts. By bridging polymer science, environmental engineering, and materials chemistry, this Special Issue aims to address global challenges such as water pollution and sustainable energy technologies.

Abstract
Efficient wastewater treatment, particularly the removal of heavy metal ions, remains a challenging priority in environmental remediation. This study introduces a novel sandwich-structured nanocomposite, RGO-CuS-PPy, composed of reduced graphene oxide (RGO), copper sulfide (CuS), and polypyrrole (PPy), synthesized via a straightforward hydrothermal method.

Efficient wastewater treatment, particularly the removal of heavy metal ions, remains a challenging priority in environmental remediation. This study introduces a novel sandwich-structured nanocomposite, RGO-CuS-PPy, composed of reduced graphene oxide (RGO), copper sulfide (CuS), and polypyrrole (PPy), synthesized via a straightforward hydrothermal method. The unique combination of RGO, CuS, and PPy offers enhanced adsorption capacity for Ni(II) ions due to RGO’s high surface area and CuS’s active binding sites, supported by PPy’s structural stability contributions. This study is among the first to explore this specific nanocomposite architecture for Ni(II) removal, achieving an adsorption capacity of 166.67 mg/g and a high removal efficiency of 94.9% within 210 min for 55 mg/L of Ni(II) concentration at pH 6 and adsorbent dose of 3 mg/15 mL. The kinetic analysis shows the best fitted time-dependent experimental data with the pseudo-second-order model, indicating chemisorption. Isotherm studies confirmed the Langmuir model as the best fit, yielding a high monolayer adsorption capacity of 166.67 mg/g. Thermodynamic analysis shows the adsorption process was endothermic (ΔH° = 80.23 kJ/mol) and spontaneous (ΔG° ranging from −6.985 to −14.399 kJ/mol). Additionally, reusability tests using 0.1 M HCl for desorption demonstrated good reusability, emphasizing the RGO-CuS-PPy nanocomposite’s potential as a sustainable adsorbent for Ni(II) removal in wastewater treatment applications.
