Electrospun polylactic acid/ tungsten oxide/ amino-functionalized carbon quantum dots (PLA/WO3/N-CQDs) fibers for oil/water separation and photocatalytic decolorization

Oily wastewater generated from various industrial processes and oil spillages is a massive threat to the environment human health. Hence, it essential develop novel material for practical oil/water separation recovery. By incorporating WO3 (tungsten oxide)/ N-CQDs (amino-functionalized carbon quantum dots) into matrix of polymer, alteration wettability behavior electrospun PLA fiber reported in this present work. The modified PLA/WO3/N-CQDs fibers shows significantly enhanced hydrophobicity while maintaining surface super-oleophilicity. These behaviors are achieved by modifying contact angle morphology composite using WO3/N-CQDs as filler. EDA exhibits highest water (WCA) at 132.37º, absorption capacity 35.752 g/g n-hexane, performance 8,326.048 L m−2 h−1 n-hexane 11,961.364 n-heptane, decolorization methylene blue (MB) 91.80%. Additionally, demonstrated an excellent durability after ten times cyclic test. This study contributes potential application field oily treatment.
