"Characterization of Nanocomposite Pseudoboemita nanoparticles Containing polystyrene obtained by Sol-Gel Process" was awarded best poster presented in the "12th International Conference on Diffusion in Solids and Liquids-DSL 2016", held in Split, Croatia, from 26 to 30 June 2016.

The work is authored by Leila Figueiredo de Miranda, Jon Jeane Pastrolin George, Alexander Crioruska Donadon, Fabio Yuji Yamasaki, Antonio Hortêncio Munhoz Junior and Leonardo g. de Andrade e Silva, researcher at the technology center of radiation (CTR). This research is being carried out in partnership with the Mackenzie Presbyterian University.

At work, were obtained polystyrene (PS) Nanocomposites with different concentrations of pseudoboemita synthesized by sol-gel process. The results showed an increase of thermal properties, hardness and tensile strength and reduction in the melt index, on impact resistance and elongation, demonstrating that there was interaction between the load with the polymer matrix. The nanocomposite properties obtained better than pure polystyrene and allow their use in environments with higher temperatures in which the PS pure does not resist.
