Synthesis and Study of the Effect of Nanoparticles in a Polymer Matrix

Composed materials of polymer with nanoparticles have been considered an important area of research for many years because its properties combination, resulting in new materials with enhanced electrical, mechanical, thermal and optical properties. The dispersion of nanoparticles in a matrix represents a serious challenge. When good dispersion is achieved, the properties of the composite are substantially different from that of the polymer matrix, enhancing its performance for different applications.

The aim of this work was the synthesis and study of Cadmium sulfide(CdS)-and carbon nanotubes (CNTs) in a matrix of poly(methyl methacrylate) PMMA. PMMA-CdS-CNTs films were analyzed by X-ray diffraction (XRD), Raman spectroscopy, UV-visible, I-V curves, optical and scanning electron microscopy (SEM). XRD and Raman studies show main characteristics of PMMA, nanotubes and CdS. A high dispersion of particles of CdS and nanotubes was observed by SEM and the conductive of the film was analyzed by IV-curves.
