THE EFFECT OF pH ON THE SYNTHESIS AND CHARACTERIZATION OF HYDROXYAPATITEPOLYETHYLENE GLYCOL COMPOSITES BY IN-SITU PROCESS

Hydroxyapatite (HAp) has a structure and chemical composition similar to bone and teeth, so Hap is widely used in the biomedical field. However, Hap has the disadvantage of being brittle, so it needs to be composited with polyethylene glycol (PEG) using an in-situ method with the aim of improving the mechanical properties of Hap. X-Rays Diffraction (XRD) results show a diffraction pattern at an angle of 2θ which is in accordance with the Hap standard (ICSD #97849). Fourier-Transform infrared (FTIR) characterization showed the presence of Hap and PEG functional group vibrations. Characterization of Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS) showed that the synthesis pH can be morphological and Hap ratio. Thermogravimetric Differential Analysis Thermal Analysis (TGA-DTA) analyzed that the HAP/PEG composites decreased in weight at temperatures >200°C due to the decomposition of organic compounds originating from PEG. The results of the Hap/PEG composite degradation behavior test showed that pH 10 was the optimum synthesis pH.

期刊介绍： RASĀYAN Journal of Chemistry [RJC] signifies a confluence of diverse streams of chemistry to stir up the cerebral powers of its contributors and readers. By introducing the journal by this name, we humbly intent to provide an open platform to all researchers, academicians and readers to showcase their ideas and research findings among the people of their own fraternity and to share their vast repository of knowledge and information. The journal seeks to embody the spirit of enquiry and innovation to augment the richness of existing chemistry literature and theories. We also aim towards making this journal an unparalleled reservoir of information and in process aspire to inculcate and expand the research aptitude.
