Abstract

Abstract: 3D and robust Poly(l ‐lactide) (PLLA) fibrous materials has been fabricated via electrospinning and evaporation welding for high‐efficiency dye adsorption and oil/water separation simultaneously. Herein, sodium dodecyl benzene sulfonate (SDBS) in spinning solution has been found to stimulate fibrous materials forming 3D candy‐floss‐like structure with high porosity and surface area. Also, SDBS doped on fibers surface facilitates dye adsorption and oil separation of the fibrous materials in effluent. Environmentally friendly SDBS‐driven 3D electrospun PLLA fibrous materials have high porosity (99.91%) and stable big pore size (7.39 µm), showing high adsorption capacity of 581.78 mg g −1 toward methylene blue (MB) and 14.67 times improved oil/water separation efficiency compared to traditional 2D PLLA fibrous materials. Moreover, the concept of SDBS stimulated 3D nanofibrous materials can be readily extended to other polymers, paving a new way to fabricate high‐efficient dye adsorption and oil/water separation 3D fibrous filters for industrial waste water remediation. Abstract : Robust candy‐floss‐like poly(l ‐lactide) (PLLA) fibrous materials driven by sodium dodecyl benzene sulfonate (SDBS) has been fabricated via electrospinning and evaporation welding. Environmental friendly 3D PLLA fibrous materials show high adsorption capacity toward methylene blue (MB) and dramatically improved oil/water separation efficiency compared to traditional 2D PLLA fibrous materials.
