Pure anatase, pure rutile and the mixed TiO2 crystals with different amounts of rutile and anatase were prepared by a hydrothermal method using Ti (OBu)4 as starting material. The effect of anions on crystal phase and morphology of TiO2 synthesized by the hydrothermal method was investigated, and the relevant mechanism was also discussed. The X-ray diffraction (XRD) results indicate that Cl- ion was in favor of the formation of rutile, while NO3- and CH3COO- were beneficial for the formation of anatase. The hydrothermal conditions have significant effects on the phase component, morphology, and particle size of obtained titania products. Additionally, mixed TiO2 crystals with different amounts of rutile and anatase could be prepared by adjusting the reaction conditions, such as the concentration of Cl- ion, hydrothermal time, the amount of citric acid and the concentration of tetrabutyl titanate.

A coagulation method providing a better dispersion of nano-Antimony-Doped Tin Oxide (ATO) in a polymer matrix was used to produce nano-ATO/poly(methyl methacrylate) (PMMA) composites. Scanning electron microscopy showed an improved dispersion of nano-ATO in the PMMA matrix, which is a key factor to determine the composite performance. Moreover, the PMMA with the addition of nano-ATO showed improved electrical conductivity and thermal stability.

The Polyaniline-poly(vinyl alcohol)-intercalated graphite oxide (GO) composites were synthesized through in-situ polymerization methods. The characterizations were illuminated by using X-ray diffraction (XRD), scanning electron microscopy (SEM), cyclic voltammetry(CV) and thermal analysis(TGA), respectively. TGA shows that composites have stable thermal properties. CV curves show charge-transport processes within the film are diffusion-controlled. The new composites reveal the potential application in the future.

An organic octupolar molecule with active hydroxyl groups was designed and synthesized. The structure and propertie of the organic molecule was characterized by IR,1H MNR, UV-vis and DSC-TG. The maximum absorption wavelength of the compound is 439 nm. The critical wavelength is below 710 nm. The compound is thermally stable with the decomposition temperature of 401°C, and consequently could be considered to be a better choice for the preparation of NLO material.
