Preparation of a novel polymer monolith using atom transfer radical polymerization method for solid phase extraction

Polylactic acid-based membranes received considerable attention due to its novel biocompatibility, renewability, and biodegradability. In this study, PLA electrospun nanofibrous membrane was prepared and 2-dimethylaminoethyl methacrylate (DMAEMA) was used as a monomer for surface grafting of polymer chains via the atom transfer radical polymerization method. Then the PLA nanofibers were quaternized by using bromoethane. The characterization of poly(DMAEMA) graft PLA nanofiber (poly(DMAEMA)-g-PLA) membranes was done by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and energy dispersive X-ray spectroscopy. The results showed that the diameter of PLA nanofibers increased 15% as the concentration increased from 10% to 12% and then increased 23% as the concentration of PLA solution increased from 10% to 15%. But the regularity of average diameters is best achieved at 12% concentration.

Ethylmorphine is an opioid that has therapeutic effects as narcotic analgesic and antitussive, which has low levels and can be misused. Hence, it is crucial to monitor by analyze the levels of ethylmorphine in blood selectively. The preparation method that can be used to extract ethylmorphine from the sample is using molecular imprinting solid-phase extraction (MI-SPE) due to its sensitivity and selectivity. This study aims to compare the result of synthesis using two different polymerization methods, and also to examine the analytical performance and characteristics of imprinted polymers from two distinct functional monomers: methacrylic acid (MAA) and acrylamide (AM). The stages of this study include the determination of association constants, synthesis of polymer MI-SPE ethylmorphine using bulk and precipitation polymerization method, extracted template from the polymer, and determined the adsorption ability, capacity, and selectivity of the polymer. MI-SPE that has been made then characterized by using Fourier-Transform Infrared (FTIR) and Scanning Electron Microscope (SEM). The results showed that MIP with acrylamide (MIP-AM) as functional monomer and made by precipitation polymerization had better analytic performances than MIP that made by bulk polymerization, with affinity value 0.072 mg/g and homogeneity value -0.77. It is also selective toward ethylmorphine with imprinting factor value 27.43. In addition, the result of characterization using FTIR and SEM showed that MIP-AM 2, MIP-MAA 1, and MIP-MAA 2 might have a low degree of polymerization due to the presence of vinyl peaks, besides MIP-AM 2 and MIP-MAA 2 had smaller particle size than the NIP with an average value of 0,31 ± 0,21 mm and 0.28 ± 0.05 mm. Based on the result of this study, MIP-AM made by precipitation polymerization could be used to extract ethylmorphine on solid-phase extraction.
