Year: 2024

Type: article

Abstract: The rapid advancement of industrial production has led to an increase in water pollutants, posing a significant threat to public health. With the deepening of research on pollutant adsorbents. The application of silsesquioxane‐based cross‐linked polymer networks in water pollution treatment has gradually attracted people‘s attention. This study introduces two new crosslinked hybrid network, PCS‐OB and PCS‐OP, which were created through one‐step amine‐ene reaction between octa(aminophenyl) silsesquioxane (OAPS) and bismaleimide or N, N′‐1,3‐phenylenedimaleimide. The synthesized hybrid networks were characterized using Fourier‐transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) surface area analysis, thermogravimetric analysis (TGA), and solid‐state nuclear magnetic resonance (NMR) spectroscopy. The successful synthesis of the material is proved. PCS‐OB and PCS‐OP exhibited remarkable efficiency in the adsorption and removal of contaminants such as antibiotics, dyes, and iodine from wastewater. The maximum adsorbents for Rhodamine B (RhB), iodine vapor and berberine hydrochloride (BCH) were 1069 mg g−1, 1590 mg g−1 and 294 mg g−1, respectively. In conclusion, this work proves that PCS‐OB and PCS‐OP have broad application prospects in pollutant treatment.
