“…Nevertheless, the SEM image of the modified membrane ( Figure 9 b) reveals no dense existence of E. coli on the membrane surface that is associated with the hydrophilicity of GO/Pt modifiers. The hydrophilic surface formed a film layer of water on its surface that could prevent bacterial growth and reproduction, resulting in great antibacterial and anti-biofouling results [ 51 , 52 ].…”

Nanofiltration processes for the removal of emerging contaminants such as nitrate are a focus of attention of research works as an efficient technique for providing drinking water for people. Polysulfone (PSF) nanofiltration membranes containing graphene oxide (GO)/Pt (0, 0.25, 0.5, 0.75, 1 wt%) nanoparticles were generated with the phase inversion pathway. The as-synthesized samples were characterized by FTIR, SEM, AFM, and contact angle tests to study the effect of GO/Pt on hydrophilicity and antibacterial characteristics. The results conveyed that insertion of GO/Pt dramatically improved the biofouling resistance of the membranes. Permeation experiments indicated that PSF membrane embracing 0.75 wt% GO/Pt nanoparticles had the highest nitrate flux and rejection ability. The membrane’s configuration was simulated using OPEN-MX simulating software indicating membranes maintaining 0.75 wt% of GO/Pt nanoparticles revealed the highest stability, which is well in accordance with experimental outcomes.

“…The leaching of biocides would have negative impacts on the environment and could cause the fading of the membrane biofouling effect. 23,24 Natural antibacterial materials, such as capsaicin and its derivatives, also indicated potential for membrane biofouling prevention by disrupting the integrity of the bacterial cell membrane and inhibiting protein production within the bacterial cell, which fortunately are usually safe for human beings. 25,26 Several studies have explored the use of capsaicin derivatives for preparation of anti-biofouling membranes.…”

This study reports the fabrication of a serious of anisotropic composite aerogels comprising polyimide and graphene (PI/G) through a simple and eco‐friendly technique. Poly(amic acid) ammonium salt/graphene dispersion, which was produced through the mixture of poly(amic acid), graphene aqueous dispersion, triethylamine, and water, was utilized in the process of creating PI/G composite aerogels employing unidirectional freezing, freeze‐drying, and thermal imidization. The PI/G aerogels displayed anisotropic mechanical properties, thermal insulation, and electrical conductivity. The PI/G aerogels with an anisotropic microstructure demonstrated notable rigidity and a high compressive modulus (52.7 MPa) along the axial direction, while displaying favorable flexibility and a low modulus (18.2 MPa) along the radial direction. Furthermore, the PI/G aerogel exhibited anisotropic thermal conductivity (axial: 64 mW m−1 K−1; radical: 55 mW m−1 K−1). These properties enable the PI/G aerogel to have a wider range of potential applications, especially strain sensors. The research presented herein establishes a simple and eco‐friendly strategy for the production of anisotropic PI/G‐based composite aerogels.
