- Environmental Science
Background:
- Solvent properties critically influence electrospinning outcomes and fiber characteristics.
- Optimizing solutions involves balancing thermodynamic stability, viscosity, evaporation rate, and dielectric constant.
Purpose of the Study:
- To fabricate highly porous poly-2,6-diphenyl-p-phenylene oxide (PPPO) fibers via electrospinning.
- To evaluate the adsorption performance of these PPPO fibers for volatile organic compound (VOC) sampling.
Main Methods:
- Electrospinning of PPPO using binary and ternary solvent mixtures.
- Characterization of fiber porosity, surface area, and morphology.
- Adsorption performance evaluation under passive and dynamic conditions using Musk Xylene.
Main Results:
- Fabricated PPPO fibers exhibit significant surface and core porosity.
