The aim of this study is to evaluate the effects of 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer coating with various concentrations onto acrylic resin denture base material on surface characteristics such as contact angle and surface roughness and on Candida albicans adhesion which is the major factor of denture stomatitis. Specimens, prepared from heat-polymerized acrylic denture base material, were divided into control and three test groups, randomly. Surfaces of the specimens in test groups were coated with poly(MPC) (PMPC) by graft polymerization of MPC in different concentrations (0.25 mol/L; 0.50 mol/L and 0.75 mol/L), while no surface treatment was applied to the control group. Contact angles and surface roughness were examined, and chemical composition of the surfaces was analyzed by Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (FTIR) to verify the presence of PMPC coatings. Then, specimens were incubated with C. albicans for 18 h and the number of adhered cells was determined. Upon PMPC coating, the contact angle values statistically decreased, but no difference was found in surface roughness values. A statistically significant decrease was observed in C. albicans adhesion in parallel with the increase in the MPC polymer concentration. There was no significant difference between 0.50 mol/L and 0.75 mol/L groups in terms of adhesion. These findings indicated that graft polymerization of MPC on acrylic denture base material reduces the adhesion of C. albicans, and may be evaluated as a coating for prevention of denture stomatitis.

Synthesis and characterization of waterborne silane coupling agent containing silicone-acrylic resin Akın, Özlem; Aras, Leyla; Department of Polymer Science and Technology (2004) In this study, waterborne silicone-acrylic resin was produced by incorporating silane coupling agent onto the acrylic main chain by emulsion polymerization. After applying different emulsion polymerization processes, batch polymerization was selected to obtain the resultant resin. Thus finding the optimum conditions by investigating the parameters of monomer ratios, initiators, concentrations of initiators, temperature and time, the novel resin was synthesized. Water-dispersed silicone-acrylic resin was pro...
The effects of some methacrylate monomers used as liquid component on tensile and flexural strengths of a poly (methyl methacrylate) denture base resin Do'an, Orhan Murat; Bolayir, Giray; Keskin, Selda; Boztug, Ali; Do'an, Arife; Bek, Buelent (2006-12-01) This study was conducted to observe the effect of different monomers on tensile and flexural strengths of poly (methyl methacrylate) (PMMA) denture base resin when they were used as a liquid component. A conventional heat-cured denture base polymer powder was mixed with ethyl, isobutyl and tert-butyl methacrylate monomers, respectively. After the polymerization process was completed, the tensile and flexural strength values of these specimens were compared with those that of PMMA resin specimens polymerized...
Study on the properties of crosslinking of poly(ethylene oxide) and hydroxyapatite-poly(ethylene oxide) composite Banat, R; Tincer, T (2003-10-10) This study covers the crosslinking of poly-(ethylene oxide) (PEO) and its composite with calcium hydroxyapatite (HA), their mechanical and swelling properties, and morphology. Sheets of the composites of PEO (two different grades with M-v: 5x10(6) and 2x10(5)) and HA and neat PEO were prepared by compression molding. The prepared composite. and. PEO (0.1-mm-thick) sheets were crosslinked with exposure of UV-irradiation in the presence of a photoinitiator, acetophenone (AP). This simple method for crosslinki...
Characterization and Electrical Conductivity of Poly(ethylene glycol)/Polyacrylonitrile/Multiwalled Carbon Nanotube Composites Aqeel, Salem M.; Kucukyavuz, Zuhal (Wiley, 2011-01-05) Polymer blends based on poly(ethylene glycol), polyacrylonitrile, and multiwalled carbon nanotubes (MWNTs) were prepared by the solvent cast technique from the dispersion of the MWNTs in the concentration range 0-3.45 wt %. The interaction of the MWNTs with the polymer blend was confirmed by a Fourier transform infrared (FTIR) spectroscopy study. The thermal properties of the polymer blend with the MWNTs were carried out by means of differential scanning calorimetry (DSC). It was evident from DSC that the p...
Investigations of the flax fiber/thermoplastic polyurethane eco-composites: Influence of isocyanate modification of flax fiber surface Tayfun, Umit; DOĞAN, Mehmet; Bayramlı, Erdal (2017-12-01) In this study, alkali and isocyanate surface modifications were applied to flax fiber (FF) to improve its adhesion to bio-based thermoplastic polyurethane (TPU) matrix. In addition to these treatments, isocyanate treated FF was subjected to curing process. TPU/FF composites were prepared at a constant 30 wt% loading of the total by using melt-blending method. Their mechanical properties, modulus of elasticity, melt-flow, water uptake and morphological properties were investigated. All of the surface modific...
