Abstract

Ion-imprinting technology (IIT) has been used to prepare the ion-imprinted polymers (IIPs) for the sorption of metal ions with high selectivity. To design selective and specific recognition sites, ion imprinting used alteration methods to detect targets by mimicking natural recognition ions. In this research, we synthesized the imprinting polymer nanofiber. Nanofiber (NF) has been synthesized using polyacrylonitrile (PAN) polymer dissolved in dimethylformamide (DMF) with electrospinning method. In order to study the technique to immobilize imprinting polymer onto nanofiber, we tried it with non-imprinted polymer (NIP) with coating method. Here, we studied the efficiency of this method. To synthesize the NIP, we used ethylene glycol dimethacrylate (EGDMA), benzoyl peroxide (BPO) and acetonitrile as crosslinking agent, free radical initiator and porogen, respectively. Scanning Electron Microscope (SEM) and cross-section have been used to study the morphology of synthesized NIP-NF. From this work, we studied the technique to synthesize NF and to modify it with imprinting polymer technology.
