  • Thermal Properties of Composite Polymer Electrolytes Poly(Ethylene Oxide)/Sodium Trifluoroacetate/Aluminum Oxide (PEO)10CF3COONa + x wt.% al2o3
    Materials (Basel Switzerland), 2019
    Co-Authors: Miguel Iban Delgado Rosero, Nori Magali Jurado Meneses, Ramiro Uribe Kaffure

    Abstract:

    Polymeric membranes of poly(ethylene Oxide) (PEO) and sodium trifluoroacetate (PEO:CF3COONa) combined with different concentrations of Aluminum Oxide (al2o3) particles were analyzed by impedance spectroscopy, differential scanning calorimetry (DSC) and thermogravimetry (TGA). DSC results show changes in the crystalline fraction of PEO when the concentration of al2o3 is increased. TGA analysis showed thermal stability up to 430 K showing small changes with the addition of alumina particles. The decrease in crystalline fraction for membranes with low al2o3 concentration is associated with the increase in conductivity of (PEO)10CF3COONa + x wt.% al2o3 composites.

  • Controlling the transmission at the surface plasmon resonance of nanocomposite films using photonic structures
    Applied Physics Letters, 2003
    Co-Authors: A. Suárez-garcía, R. Del Coso, Rosalía Serna, Javier Solis, C. N. Afonso

    Abstract:

    The transmission of nanocomposite thin films formed by Cu nanocrystals embedded in an amorphous Aluminum Oxide (al2o3) matrix has been enhanced in the vicinity of the surface plasmon resonance wavelength, by the design of one-dimensional photonic structures. The nanocrystals are distributed in layers, whose separation and periodicity are used to control the optical response of the films. It is found that at the SPR a transmission enhancement up to 36% can be achieved with respect to a film with an homogeneous distribution of the nanocrystals. These photonic structures have been successfully produced by pulsed laser deposition.
