| Abstract: | Our research described in this report introduces a multifunctional composite resin, TiO2/SiO2@poly(hexadecyl methacrylate-co-butyl methacrylate-co-methyl acrylate), synthesized to enhance oil absorption and demulsification for oily wastewater treatment. By incorporating hydrophobically modified nano-titanium dioxide (nano-TiO2) and nano-silicon dioxide (nano-SiO2) into a polyacrylate resin through suspension polymerization, we aimed to overcome the limitations of traditional oil absorbent resins. The resin's formulation included hexadecyl methacrylate, butyl methacrylate, and methyl acrylate. Characterization was conducted through measurements of contact angle, Fourier-transform infrared spectroscopy, scanning electron microscopy, and Brunauer–Emmett–Teller surface area analyses. The study meticulously optimized the chemical synthesis conditions, focusing on the amount of monomer, initiator and crosslinker, which are crucial for the polymerization reaction. Additionally, the physical parameters, such as the particle size and quantity of the nano-materials, were carefully controlled to achieve the desired material properties. The inclusion of nano-TiO2 and nano-SiO2 significantly enriched the resin's porous structure, boosting its oil absorption ratios for oil in various solvents, notably enhancing stability and recyclability. The resin exhibited superior oil absorption capacities (e.g. 54.7 g/g for trichloromethane) and improved emulsion separation efficiency (e.g. 98.10% for trichloromethane emulsions), marking a substantial advancement in materials for environmental remediation applications.
