Influence of TiO<inf>2</inf> Nanoparticles on Enhancing the Properties Activity of Organic Polymeric Materials for Industrial Applications

Abstract

Novel composite (MC/TiO2) films consisting of titanium dioxide nanoparticles (TiO2NPs) and organic polymer methylcellulose (MC), were synthesized for applied in photocatalysis and industrial sectors. The preparation of the nanocomposites MC/TiO2 films were verified successfully by EDX technique, which demonstrated the uniform distribution of TiO2 in the MC. Moreover, in frequency of 20 Hz to 5.5 MHz, the dielectric properties of MC as a function of TiO2 concentration were determined. The conductivity improved from 5.8 × 10−8S.cm−1 for MC to 3.8 × 10−6S.cm−1 for the composite MC/TiO2, and the dielectric constant ϵ ′ has risen from 87 for MC to 179 for the composite MC/TiO2. In addition, the energy density increases from 3.86 × 10−4J m−3 for MC to 7.94 × 10−4J m−3 for MC/TiO2, and the relaxation time τ r dropped from 11.5 × 10−5 sec to 2.58 × 10−5. In summary, the data investigated that the dielectric characteristics of MC/TiO2 were modified for usage in different applications as wastewater treatment and energy storage devices.
