New dielectric and semi conducting hybrid inorganic-organic material based on Zr(O(CH2)3CH3)4, glycerol and EMIm TFSI ionic liquid

Multifunctional hybrid materials combining intimately mixed organic and inorganic components con yield high-performance materials with properties not found in either component individually. Combining inorganic and organic structures on a molecular scale to form glasslike materials is the challenging task due to very different formation reactions of inorganic and organic networks. A new hybrid inorganic-organic material is syntheses by sol-gel method using Glycerol and Zirconium(IV)butoxide, Zr(O(CH2)3(CH2)4) as precursors. This material is also doped by means of EMImTFI ionic liquid which is insoluble in water. The material is characterized from: a) three-dimensional structure where Zr atoms are bound between them by means of molecular organic fragments b) electrical activation by means of EMImTFSI Ionic liquid. The elemental composition of the material [Zr(C11O4H31)] has been determined by CHN analyzer and ICP-AES measurements. FT-IR and Raman spectroscopy investigations have been performed in order to study the molecular structure of the material and interactions of the EMImTFSI with the host networks. Differential Scanning Calorimetry measurements show the presence of two glass transition temperature T. The broad band dielectric spectroscopic measurements have carried out in the range of 10-2Hz to 10 MHz between -100°C to 100°C. The conductivity of the material [Zr(C11O4H31)] has been found to be in the order of 10-12 to 10-11 S/cm, so it con he defined as a dielectric material. After the addition of ionic liquid the conductivity is increased udue to the creation of free charge carriers in the host material.
