Preparation technology and parameters of partially electrospun functional fiber membranes for antibiotic removal.

Types of Polymers	Pretreatment Technology	Post-Treatment Technology	Effect on Antibiotic Removal	Reference
Polylactic acid	Doping TiO2 into PLA solution (Acetone/DMF = 3/2 v/v)	The fibers were deposited on fiberglass supports to prepare fiberglass fabric plain woven-type membrane, fiberglass mat-type membrane and fiberglass fabric one-fold edge-type membrane	After photocatalytic 30 min, AC was almost completely removed in aqueous solution, and the removal effect of fiberglass fabric plain woven-type membrane was the best	[12]
Polysulfone	Mixing TiO2/AgNPs composite particles into PSF solution (DMF/NMP = 7/3 v/v)	Polyamide active coating was formed on the membrane surface by interfacial polymerization	The permeability of TC resistance gene in the membrane was less than 9%	[14]
Polyethylene terephthalate	Dispersing g-C3N4 into the PET solution (HFIP)	After heat treating the PET fibers in alkaline aqueous solution in 65 °C for 1.5 h, g-C3N4 was exposed to the surface of PET and transformed from deactivation to reappearance	Under sunlight, the photocatalytic activity for the degradation of antibiotics such as SQX and SD was high, and the photodegradation rate of SQX reached 100% (pH = 5) in 2.5 h	[124]
Polyvinylpyrrolidone	Putting TiO2 gel into PVP solution (ethanol)	g-C3N4 nano-sheath was formed on the fiber surfaces by in-situ thermal polymerization	The photodegradation rate of TC was as high as 90.8% in 60 min, and the inactivation of Escherichia coli was 6 log after visible light irradiation on 90 min	[125]
Polyethylene glycol, Polyethylene terephthalate	Adding PEG into the mixed solution of g-C3N4 and PET (HFIP)	The fiber membrane was soaked in a water bath at 60 °C for 24 h, and the porous fiber was obtained by removing PEG	Under visible light, the degradation efficiency of SQX reached 100% in 2 h	[127]
Polyvinyl alcohol	Adding 20% urea to PVA solution (water)	The PVA fibers were immersed in FeCl3 aqueous solution for Fe3+ complexation and then using NaBH4 solution to reduce Fe3+, ZVI NPs was synthesized in situ and immobilized, and then freeze-dried	The adsorption equilibrium of STZ was reached in 570 min, and the electrocatalysis degradation of STZ reached 100% in 5 min	[128]
