Special Issue Information

Dear Colleagues,

This Special Issue focuses on the preparation and characterization of carbon-based polymer nanocomposites, aiming to improve the mechanical and functional properties of polymer materials. This Special Issue deals with the fabrication techniques employed to incorporate carbon materials into polymer matrices, exploring various methods like solution blending, melt processing, and chemical vapor deposition. Each method offers distinct advantages and challenges, affecting the dispersion and alignment of carbon materials within the polymer matrix. Understanding these fabrication techniques is crucial to achieving optimal composite properties. The characterization process employs a range of sophisticated analytical techniques, which provide valuable insights into the composite's microstructure, mechanical behavior, thermal stability, and electrical conductivity.

This Special Issue entitled “Carbon-Based Polymer Nanocomposites: Preparation, Characterization, and Applications, 2nd Edition”, aims to form a collection of high-quality original/review papers focusing on recent progress and new preparations in the application of carbon-based polymer nanocomposites, including (a) the synthesis and surface modification of carbon materials; (b) the tailored control of carbon materials’ size, concentration, and orientation in a polymer matrix; (c) interfacial property control between carbon materials and the polymer matrix; (d) the evaluation of carbon materials’ dispersion state in the polymer matrix; (e) and the development of new applications using carbon-based polymer nanocomposites and various nanocomposites.

Proton exchange membrane fuel cells are environmentally friendly, safe clean energy devices that have the potential to change the world. Proton exchange membrane fuel cells are a promising replacement for traditional power generation devices. Nanocomposite proton exchange membranes have high energy efficiency, which allows them to be considered as a new generation of proton exchange materials. This paper presents for the first time the synthesis and properties of nanocomposite proton exchange membranes based on poly-1-vinyl-1,2,4-triazole modified with polyhydroxysulfonated fullerene. Sulfofullerene intercalated into the polymer matrix improves all key membrane properties. The PEM nanocomposites exhibit a proton conductivity of up to 1.67 mS/cm and a uniform distribution of carbon nanoparticles of up to 10 nm in size. It was established that high dispersion and stabilization of nanoparticles are ensured by the acid–base interaction of sulfofullerene with the heterocycles of the polymer matrix. Stabilization of functionalized fullerenes by a matrix of semi-interpenetrating polymer networks is an innovative approach for creating nanocomposite proton-conducting systems. The obtained fullerene-containing PEMs demonstrate a high potential for wide practical application in various fuel cells. Full article

In this work, pCh-MWCNTs@Ag-TiO2/S and pCh-MWCNTs@Ag-TiO2 nanocomposites were synthesized through a combined phosphorylation and cross-linked polymerization method. The materials were thoroughly characterized using several analytical techniques, including SEM/EDS, FTIR, TGA, and BET analysis. SEM images revealed that the pCh-MWCNTs@Ag-TiO2/S nanocomposite displayed a smooth, flake-like morphology with spherical, dark greenish particles. EDS analysis confirmed the presence of Si, S, P, and Ag as prominent elements, with Ti, C, and O showing the most intense peaks. The TGA curves indicated significant weight loss between 250–610 °C for pCh-MWCNTs@Ag-TiO2 and 210–630 °C for pCh-MWCNTs@Ag-TiO2/S, corresponding to the decomposition of organic components. FTIR spectra validated the existence of functional groups such as hydroxyl (-OH), carboxyl (-COOH), and carbonyl (-C=O) on the surface of the nanocomposites. Following characterization, the materials were evaluated for their capacity to adsorb Hg2+ at parts-per-billion (ppb) concentrations in contaminated water. Batch adsorption experiments identified optimal conditions for mercury removal. For pCh-MWCNTs@Ag-TiO2, the best performance was observed at pH 4, with an adsorbent dose of 4.0 mg, initial mercury concentration of 16 ppb, and a contact time of 90 min. For pCh-MWCNTs@Ag-TiO2/S, optimal conditions were at pH 6, a dosage of 3.5 mg, the same initial concentration, and a contact time of 100 min. Each parameter was optimized to determine the most effective conditions for Hg2+ removal. The nanocomposites showed high efficiency, achieving more than 95% mercury removal under these conditions. Kinetic studies indicated that the adsorption process followed a pseudo-second-order model, while the equilibrium data aligned best with the Langmuir isotherm, suggesting monolayer adsorption behavior. Overall, this research highlights the effectiveness of sulfur-modified chitosan-based nanocomposites as eco-friendly and efficient adsorbents for the removal of mercury from aqueous systems, offering a promising solution for water purification and environmental protection.

Dimethyl methylphosphonate (DMMP) and modified nano-silica were utilised to enhance the mechanical properties, thermal stability, and flame retardancy of waterborne polyurethane (WPU). Nano-silica modified with the silane coupling agent γ-aminopropyltriethoxysilane (KH550) exhibited excellent dispersibility and stability. Compared with pure WPU, the limiting oxygen index (LOI) of P/Si-WPU increased from 18.1% to 28.3%, and its UL-94 rating reached V-0, with a significant improvement in elongation at break. Furthermore, the peak heat release rate of P/Si-WPU decreased by 29.1%, while the total heat release was reduced by 6.8% in comparison to pure WPU. The synergistic flame-retardant mechanism of phosphorus and silicon was investigated through an analysis of the char residue of WPU and its composites. This study provides a potential approach for the development of WPU with superior flame retardancy and enhanced mechanical properties. Full article
