This work describes the polyaniline (PANI) nanoparticles' impregnation into the polystyrene (PS) membrane and its impact on the different membrane properties for the first time. PANI nanoparticles were synthesized separately using the oxidative polymerization technique and then impregnated into the polystyrene‐DMF matrix solution. Membranes were cast via the Non‐Solvent Induced Phase Separation (NIPS) process. The surface and structural properties of the fabricated membranes were thoroughly characterized using contact angle measurement (CA), x‐ray diffraction (XRD), Fourier‐transform infrared spectrometer (FTIR), and scanning electron microscopy (SEM). Thermal gravimetric analysis (TGA) and the mechanical characteristics of the membrane were also investigated. According to the CA results, the addition of PANI in the matrix improved the polystyrene membrane's hydrophilicity from 65° to 54.5°. The FTIR spectra revealed that the PANI nanoparticles were successfully impregnated into the PS matrix. SEM images illustrated that the porosity of the PANI‐modified membrane was enhanced by 50% compared to the pristine PS membrane. Furthermore, adding PANI to the PS membrane significantly reduced the average pore size. The filtration experiment showed that PANI modified membrane had 81% rejection of MO dye as compared to the pristine PS membrane which had 60%. Therefore, The PANI added to the PS membrane greatly enhanced the PS membrane's structural properties.

“…The experiment was carried out using the matrix parameters from the response surface models at ACPNS-TiO 2 dosage (10-60 mg/L), pH (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), and MB concentrations of 10-50 ppm in a simulated solar photo reactor consisting of a metal halide lamp (Philips) with a photo flux of 220 Wcm 2 , a wavelength of 510 nm, and a power of 400 W placed 15 cm above the solution surface. A total 5 mL of the product was collected in a test tube at 10 min intervals and centrifuged at 6000 rpm for 10 min to remove the nanocomposite catalyst.…”

“…In addition, there are problems with waste disposal that arise before, during, and after industrial and agricultural processing [10]. Several developing nations have poor waste management systems and generate enormous volumes of this kind of trash [10,11]. Inadequate action to mitigate the resultant dangers might have disastrous consequences.…”

“…A separate class of adsorbents is represented by the polyaniline-coated carbonaceous materials, e.g., activated carbon [ 7 , 64 ]; activated carbonized peanut shells [ 65 ]; activated carbons based on prickly pear seeds [ 66 ]; carbonized tea waste [ 67 ]; graphene [ 47 , 68 ]; multiwall carbon nanotubes [ 8 ] or reduced graphene oxide [ 30 , 69 , 70 ]. Only exceptionally, polyaniline was decorated in a reverse manner by an inorganic component, such as copper(II) oxide [ 71 ].…”

Water pollution by organic dyes, and its remediation, is an important environmental issue associated with ever-increasing scientific interest. Conducting polymers have recently come to the forefront as advanced agents for removing dye. The present review reports on the progress represented by the literature published in 2020–2022 on the application of conducting polymers and their composites in the removal of dyes from aqueous media. Two composites, incorporating the most important polymers, polyaniline, and polypyrrole, have been used as efficient dye adsorbents or photocatalysts of dye decomposition. The recent application trends are outlined, and future uses also exploiting the electrical and electrochemical properties of conducting polymers are offered.
