“…The polymer utilized in this work was Poly(methylmethacrylate) PMMA, which was given by ICI and has the chemical formula (C5O2H8) n, (Mw = 100.12 g.mol -1 ), the chemical structure of which is shown in Figure 1 [6]. Chloroform was employed as a common solvent for pure PMMA (purity of 99.8% HPLC).…”

Polymers are commonly utilized sophisticated materials that may be found in nearly every item we use daily. Polymers relevance has recently been highlighted due to their applications in several fields of science, technology, and industry, ranging from fundamental usage to biopolymers and medicinal polymers. The research aims to study the effect of annealing with irradiation on the optical properties of PMMA films used in many industrial and medical applications. Where UV-Vis spectroscopy was used to study the absorption and emission spectra in calculating the optical parameters, it was found that the optical energy gap of the indirect transmission type decreases with the increase in the thickness of the thin films. Also, the optical parameters such as the absorption coefficient, refractive index, attenuation coefficient, and dielectric constants increase with increasing thickness. The character of FTIR spectra and the locations of the bands have been demonstrated to change with different time annealing temperatures with irradiation. Irradiation has been demonstrated to change the shape of FTIR Spectra and the placement of the peaks.

“…El PMMA es ópticamente transparente, siendo capaz de transmitir el espectro de la luz visible hasta en un 92,6%, tiene buenas propiedades mecánicas, presenta baja densidad, tiene una muy destacable resistencia a la intemperie y es fácil de procesar. Es por ello por lo que rivaliza con el cristal (material inorgánico) en muchas aplicaciones, pues suma a todas estas propiedades anteriores una menor fragilidad [30].…”

“…El PMMA resulta también biocompatible, comenzándose a utilizar en el 1949 en implantes de lentes intraoculares para el tratamiento de cataratas [41]. En la misma línea, y aprovechando su naturaleza rígida y resistente, también se utiliza como cemento para implantes de prótesis [30] o para odontología en la fabricación de coronas temporales, para ortodoncia [42,43], etc.…”

El polimetilmetacrilato (PMMA) es un polímero termoplástico globalmente conocido, con destacadas propiedades de transparencia, biocompatibilidad, resistencia al ambiente, rigidez y fácil procesabilidad, pero con baja resistencia a la fricción y al desgaste. En el presente trabajo se han estudiado las propiedades tribológicas del PMMA, modificándolo con diferentes concentraciones de nanofases basadas en óxido de grafeno, y óxido de grafeno modificado con el líquido iónico tetrafluoroborato de 1-octil-3-metilimidazolio ([Omim]BF4). Los nuevos nanocomposites fueron elaborados mediante los procesos industriales de extrusión y moldeo por inyección, para ser estudiados tribológicamente bajo dos tipos de contacto, lineal oscilatorio y multirrayado, realizando también una caracterización estructural completa de los nanocomposites y nanofases, aplicando técnicas como XRD, XPS, espectroscopía Raman, TEM, TGA, DSC o DMA.
