In recent years, membrane filtration has been considered an effective method for treating oily wastewater. However, membrane fouling is a major challenge inherent to this approach.</div></div><div><h3>Methods</h3><div>This study integrated zwitterionic carbon quantum dots (ZQDs) into a tannic acid-(3-aminopropyl)triethoxysilane (TA-APTES) coating on cellulose acetate (CA) tubular membranes to explore the potential for improve the hydrophilicity and anti-fouling properties of the membrane. The CA tubular membrane was fabricated by dry/wet spinning method. A green and one-step synthesis of TA-APTES with ZQDs was utilized to modify the surface of the CA pristine membrane.</div></div><div><h3>Significant findings</h3><div>Incorporating ZQDs enhanced the membrane's hydrophilicity.
