Abstract

The electrospinning method has become a leading technique in developing nanomaterials based on fiber structures (nanofibers), utilizing a high-voltage static electric field to draw a viscous solution towards the negative pole. By combining different materials, nanofibers can selectively absorb contaminants, opening opportunities for sensor detection development. One such combination is ion-imprinted polymers (IIPs). This study presents a simple optimization, including variations in the needle-to-collector distance (7, 10, and 15 cm). Metal template removal was carried out through extraction with 3 M HCl. The impact of needle-to-collector distance variation on PVA-based nanofibers was analyse through morphological observation using SEM and functional group analysis with FTIR characterization. In the IIPs Pb(II) sample, the C=O bond groups dominate, indicating the presence of EDGMA or BPO compounds, which is distinct from the PVA and Gelatin nanofibers, which are primarily dominated by -OH groups. The NF-7 sample had an average diameter of 392.3 nm, NF-10 had a smaller average diameter of 315.9 nm, and NF-15 had the smallest average diameter of 253.8 nm. The highest pore distribution at the nanoscale was observed in the NF-IIPS-Pb(II) sample at 7 cm, with a larger average diameter of 392.3 nm compared to the 10 cm and 15 cm samples. The highest adsorption capacity was found in the nanofiber with a 10 cm distance, at 17.85 mg/g Keywords: Electrospinning; Nanofiber; Morphology
