Special Issue Information

Dear Colleagues,

Polymer films, coatings, and membranes have recently found their way to a plethora of research areas, such as membrane distillation, membrane filtration, fuel cells, anticorrosion, separation processes, electrolysis cells, capacitors, and polymeric electrolytes. Simultaneously, new and environmentally degradable polymers for membranes and film fabrication have led to increased interest among researchers for the abovementioned applications. This Special Issue focuses on membrane fabrication, advanced polymers, bio-based polymers, thin polymeric films, polymer surface modifications, membrane processes, polymeric-waste recycling, additives enhancing polymer characteristics, membrane thermal characteristics, membrane for energy, environmental and chemical engineering processes, and other interrelated research topics.

Air pollution and control of gaseous air pollutants are global concerns. Exposure to these gaseous contaminants causes several health risks, especially exposure to irritant gases such as ammonia (NH3). Furthermore, the application of smart polymeric nanocomposites in environmental applications has gained significant interest in recent years. In this study, aniline was polymerized without and with clay using a carbon dioxide (CO2)-assisted polymerization technique, yielding PANI and PANC samples, respectively. The samples were characterized using different methods, such as Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscope (SEM), and Brunner Emmett Teller (BET). The synthesized nanomaterials were utilized as gas adsorbents using a fixed bed reactor to investigate their adsorption behavior towards NH3. Three inlet NH3 concentrations were tested (35–150 ppm). The results revealed that the adsorption capacities of PANC nanocomposites were higher than nanostructured PANI for the studied concentrations. The adsorption capacities were 61.34 mgNH3/gm for PANC and 73.63 mgNH3/gm for PANI at the same inlet concentration (35 ppm). The highest NH3 adsorption capacity recorded was 582.4 mg NH3/gm, for PANC. This study showed the impressive adsorption behavior of the prepared PANI and PANC nanomaterials towards NH3 gas. Consequently, nanostructured PANI and PANC can be promising adsorbents that can be utilized to control different gaseous air pollutants. Full article
