The controlled the solvo-hydro-thermal titanium dioxide synthesis moderated by dimedone from organometallic precursors is approached in order to obtain nanoparticles compatible with the polymeric systems used in the dental technique. The experiments carried out with relation to the production of titanium dioxide nanoparticles using the solvo-hydro-thermal synthesis allowed the production of three types of materials by means of varying the nature of the used solvent: methanol, ethanol and propanol (TiO2-M, TiO2-E and TiO2-P).The characterisation using electron microscopy (SEM and HRTEM), X-ray analysis, FTIR and UV-Vis spectrometry show that the diameter of the produced nanoparticles is less than 15 nm and decreases in the order: dpMethanol ] dpEthanol ] dpPropanol. The nanoparticles contain trace organic substances which the smaller they are, the bigger the alcohol chain used as a solvent is. The adsorption of a target dye showed increasing values with the increasing number of atoms in the hydrocarbon alcohol chain. The highlighted characteristics suggest the possibility of using the synthesised nanoparticles in the production of hard implants for dental reconstruction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
