Synthesis and Application of Carbon Quantum Dots Nanoparticles for Enhancing the Performance of Polyvinylidene Fluoride (PVDF) Membrane

This study explores incorporating carbon quantum dots-nanoparticles (CQDs) into polyvinylidene fluoride (PVDF) membranes to enhance filtration performance. CQDs were synthesized, characterized, and integrated into PVDF at varying concentrations. The modified membranes showed improved surface hydrophilicity, with the water contact angle decreasing from ۸۶.۹۲° to ۷۲.۴۹° and a notable increase in liquid entry pressure of water (LEPw).
