Abstract
Polyether ether ketone (PEEK) is one of the most important aromatic polymers; it has many applications in nanotechnology. The new sulfonated polyether ether ketone (sPEEK) membrane was successfully prepared, by using sulfonation processed for PEEK polymer; 10 grams of PEEK sample were dissolved progressively in 200 ml of sulfuric acid (H2SO4). The degree of sulfonation (DS) was low which was equal to 22.9 %. The goal of this study was to characterize of PEEK and sPEEK. The Characterizations of PEEK and sPEEK have been done by using X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Transmission electron microscopy (TEM) and Scanning Electron Microscope (SEM). XRD is a helpful tool for analyzing the crystalliate of the samples. FTIR spectrum analyzed the functional group of PEEK and sPEEK. SEM image has been shown the structural morphology of samples.
