Novel PVDF-CQD polymer nanocomposite membrane for removal of antibiotics from water

Carbon Quantum Dot (CQD) -based nanocomposites are widely used as fluorescent sensors for the detection of antibiotics in water; however, the use of CQDs for water remediation is largely unexplored. In this study, a novel polyvinylidene fluoride (PVDF) membrane modified with CQDs was developed by electrospinning to remove ciprofloxacin from water.  Hydrothermal method was employed to prepare CQD with polyvinylpyrrolidone (PVP) as a precursor. FTIR and XRD Studies confirmed the improved β-phase of PVDF, which is suitable for water remediation. FESEM analysis confirmed that the CQD concentration was an effective parameter for converting PVDF membrane into a porous and fibrous morphology. Among the four membranes, the electro-spun PVDF with a 0.2 ml CQD stock solution (SPVPC-2) exhibited better adsorption and photodegradation efficiency, which could be determined by UV-visible spectroscopy. SPVPC-2 achieved a maximum antibiotic removal efficiency of 81.5% after 5 h of UV exposure. The..., , # Data from: Novel PVDF-CQD polymer nanocomposite membrane for removal of antibiotics from water

**Description of the data and file structure**

Polymer Nanocomposites were synthesised using PolyVinylidene fluoride (PVDF) as host polymer and Carbon Quantum Dots(CQD)  as filler in different ratios by the electrospinning(S) method. Carbon Quantum Dots were prepared using polyvinylpyrrolidone (P) and Citric acid(C) as precursors. This is shortly referred to as SPVPC. Four samples were prepared. Based on proportions of added fillers, these are referred to as SPVPC-0, SPVPC-1, SPVPC-2, and SPVPC-3.

 The structure of the prepared polymer nanocomposite membranes was analysed using Fourier Transform InfraRed Spectroscopy(FTIR) and X-Ray Diffraction method(XRD). The morphology of the membranes was studied by Field Emission Scanning Electron Microscopy(SEM).
