| Popis | For polymeric nanocomposite structure it is necessary to use chemically fixed monomer on nanotubes. This was the main reason for preparation of functionalized titanate nanotubes by multifunctional monomers. Sodium trititanate was prepared by hydrothermal exfoliation of titanium oxide nanoparticles at concentrated hydroxide sodium environment. Hybrid monomer - titanate nanotubes was prepared by long term solvothermal functionalization of titanate nanotubes using basic or acid of multifunctional monomer. Thermal stability and decomposition of organic component was analyzed by thermal analysis (DSC/DTA). Bonded organic functional groups were identified by infrared (FTIR) and Raman spectroscopy (RS). Composition and structure of nanotube was determined by roentgen diffraction (XRD). Nanomorphology of nanotubes was displayed by scanning electron, transmission and atomic microscopy (SEM, TEM and AFM). |
