Synthesis, Electrospinning and Characterization of Schiff Base Polyvinylmethylketone and 2-Amino,4,6-Dihydroxylpyrimidine

Abstract

The Polyvinylmethylketone (polymer) was synthesized with 2-amino-4,6- dihydroxylpyrimidine (ligand) via a Schiff base condensation reaction to form a synthesized polymer and electrospun into a nanofibers. The characterization of the polyvinylmethylketone synthesized with 2-amino-4,6-dihydroxylpyrimidine electrospun nanofibers (APPMKNFs) was done using fourier transform infrared (FTIR). The peaks at 1696 cm-1 and 3139 cm-1 on the polymer and on the ligand respectively as the starting materials, these peaks however disappeared to form a new band at 1613 cm-1 indicative of the presence of imine functional group on the synthesized polymer. Elemental micro analysis (CHNS) on polymer shows the presence of functional groups of carbon and hydrogen with the absence of nitrogen before the synthesis and the presence of nitrogen after the synthesis with the ligand. The best optimum condition for the morphology using scanning electron microscope (SEM) for APPMKNFs was 20% (w/v) with diameter 127- 200 nm. The surface area of APPMKNFs, material was measured, using the BET method and the results was 114.2 m2/g.
