Item PREPARATION AND CHARACTERIZATION OF INJECTABLE POLY (METHYL METHACRYLATE) (PMMA)/ZIRCONIA COMPOSITES(2022-01-25) Abdullah, Hamad Farhan; Türkoğlu Şaşmazel, Hilal; Park, JongeeThe purpose of this study is to fabricate 3D printed biomaterials. PMMA/Zirconia biomaterials were prepared by the addition of different percent weight of Zirconia powder to PMMA solution on a hot plate at 75 ˚C with continuous magnetic stirring until the stirrer stopped. The prepared sample was injected by using a syringe to get the desirable shape. Then it was sintered at different sintering temperature. Characterization of synthesized PMMA was performed by ATR-FTIR. Characterization of samples morphology were carried out by Scanning Electron Microscopy (SEM). Crystallinity and phase transformation were investigated by X-ray Diffraction (XRD). The mechanical test was performed by applying compressive strength test. According to ATR-FTIR test, synthesized PMMA showed a degree of conversion ̴ 70%. SEM micrographs showed that porosity increases with PMMA content and decreases with the increase of sintering temperature. Particles size was different, as it refers to grains agglomeration due to sintering temperature. XRD patterns showed that the percentage volume of tetragonal phase decreases with the increase of sintering temperature and crystallite size increases with the sintering temperature. Compressive strength test showed that the compressive strength increases with the increase of sintering temperature and decreases with the increase of PMMA amount.
