Facultad de Ingeniería Mecánica. Ciencias en Ingeniería Mecánica ; Science and technology have developed in the world constantly, which has had important achievements in the area of nanomaterials during the last decades. Composites based on carbon nanomaterials and polymeric matrices are another type of promising materials due to their properties for different applications. In this research, synthesis of carbon nanostructures was carried out by CVD method using two types of carbon sources (benzene and commercial naphthalene). Multiwalled Carbon nanotubes (MWCNTs) were obtained from benzene. However, other morphologies (carbon nanotubes, nanobars and carbon spheres) were grown from commercial naphthalene at different temperatures and synthesis times. Pristine and functionalized carbon nanotubes obtained from benzene and carbon spheres with uniform morphology, obtained from pure naphthalene, were used as fillers. Polymethylmethacrylate was used as matrix in composites synthesis. CNTs/PMMA and CSs/PMMA composites were obtained as films using two types of solvents (toluene and acetone) by the mixing solution/sonication method. CSs/PMMA composites fibers were other kind of morphology which were obtained by the electrospinning method, using acetone as solvent. Different carbon nanostructures concentrations into PMMA were studied. Composites were characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy. Electrical conductivity and microhardness were evaluated in all composites. It was determined that the properties (electrical conductivity and microhardness) of the composites improve when concentration of carbon nanostructures increases, in comparison with pristine PMMA and the high values of electrical conductivity and microhardness were obtained in CS-based films. ; La ciencia y la tecnología se han desarrollado en el mundo a grandes pasos, lo cual ha tenido importantes repercusiones en el área de los ... |
