Título del libro: Technical Proceedings Of The 2014 Nsti Nanotechnology Conference And Expo, Nsti-Nanotech 2014 Título del capítulo: Development antifog nanohybrid consisting of polyestyrene recycled matrix by sol-gel process
A hybrid material consisting of SiO2 nanoparticles embedded in polystyrene recycled matrix has been developed. A polymer of polystyrene recycled functionalized (PSR-F) was used to influence the morphological and antifog properties of sol-gel synthesized silica nanohybrid. Silica nanoparticles are produced from alkoxide precursors in the presence of polystyrene recycled; hence a final material consisting of SiO2 globules entangled inside a polystyrene recycled matrix is obtained. The functionalization of the polystyrene recycled matrix has the purpose in situ of uniting these carboxyl groups OH of the surface of the silanol groups during the process sol-gel. In this way, opaque or transparent solid substrata can be obtained, each of these optical conditions depends on the amounts of reactants employed to prepare the nanohybrid specimen. The nanohybrid SiO 2/PSR-F sample was used for coatings in glass and evaluated antifog properties.
