Robust Candy‐Floss‐Like Poly(l‐lactide) Fibrous Filters Driven by Sodium‐Dodecyl‐Benzene‐Sulfonate for High Efficient Dye/Oil Separation

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 SDBSdriven 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.

Tri‐Layer Laminated Fabric‐Induced Sweating Surfaces for Passive Cooling

“…The foremost reason is that the capillary gravitation of the cotton fabric to the water droplets before treatment is larger. [ 31,32 ] After treatment, some gaps in the fabric were blocked, increasing the time for the water droplets to be completely absorbed. The contact angle test on the outer layer of TLF did not change much compared to C‐PAANa.…”

“…has drawn significant attention. [1][2][3][4][5][6][7][8][9][10] The versatility of solution electrospinning lies in its ability to produce electrospun fibers with different orientation and morphology by varying process parameters (applied voltage, receiving distance, collector type, collector speed, orifice diameter tissue engineering and biomedical applications. [38][39][40][41][42][43][44][45] The morphology, thermal, microstructural, mechanical, and viscoelastic properties of different PLA/PCL blend-based EMs have been reported in our previous studies.…”

“…has drawn significant attention. [ 1–10 ] The versatility of solution electrospinning lies in its ability to produce electrospun fibers with different orientation and morphology by varying process parameters (applied voltage, receiving distance, collector type, collector speed, orifice diameter of needle and flow rate); electrospinning solution properties (viscosity, solvent volatility, electrical conductivity, and surface tension) and ambient conditions (temperature and humidity). [ 11 ] Further, the porous, interwoven, and continuous morphology of EMs contribute to its structural analogy with the extracellular matrix of indigenous tissues and thus act as potential candidates for the fabrication of devices for various biomedical applications such as tissue engineering, drug delivery, etc.…”
