Delving into the properties of polymer nanocomposites with distinctive nano-particle quantities, for the enhancement of optoelectronic devices

Abstract

The study focusses on synthesis and modification of structural, optical and electrical characteristics of nanostructured titanium dioxide anatase embedded Poly(methyl methacrylate) (PMMA) nanocomposite with different weight percentages (0.03, 0.06, 0.12, 0.18 and 0.24%) by the solvent casting method. Modification in the morphology of PMMA nanocomposites with an increasing amount of titanium dioxide anatase is studied by using a field emission scanning electron microscope (FE-SEM). Micrograms of FE-SEM show spherical shaped nanoparticles distribution in PMMA nanocomposites thin films. In optical characterization, transmission, optical band gaps, the real and imaginary part of dielectric constant, linear susceptibility, optical conductivity, refractive index and extinction coefficient are calculated using experimental data. It is observed that the optical band gap has an overall decreasing trend with increasing the weight percentage of TiO 2 (anatase) in PMMA nanocomposites. It is also found that values of all electrical parameters decrease with increasing the weight percentage of TiO 2 (anatase) in PMMA nanocomposites. All wavelength depending parameters are investigated in the wavelength range from 190 nm to 2700 nm. Single oscillator model is used to analyze the refractive index dispersion and estimation of the oscillator energy and dispersion energy of the films. The study is applicable to optical sensors and other optoelectronic devices.

New Hybrid PVC/PVP Polymer Blend Modified with Er2O3 Nanoparticles for Optoelectronic Applications

“…The E 0 value varies in the range from 4.23 eV to 4.75 eV. It increases with increasing Er 2 O 3 content to 0.1 and 0.3 wt% and then decreases for the film doped with 0.6% Er 2 O 3 due to the electron transition probability within allowed electronic bands [ 51 ]. The E d value also varies in the range of 10 eV to 27.9 eV, depending on the concentration of Er 2 O 3 .…”

Exploring the A.C. Electrical Properties of PMMA/SiC/CdS Nanocomposites to Use in Electronics Fields

“…The drastic change in the properties of polymer nanocomposites are influenced by the type of integrated nanoparticles, their size, shape, their concentration and interaction with polymer matrix. PMMA as a conducting polymer has attracted attention for use in many applications as optical components, optical sensors and in optoelectronics devices due to their low cost and excellent physical and chemical properties [2]. The nanocomposites with PMMA matrix may be applied for optoelectronics and electronics applications [3][4][5].…”

Effects of Simulated Solar Wind on Polymethyl Methacrylate Thin Film

“…Moreover, PMMA is simple to synthesize and can be used to produce polymeric-based nanocomposites possessing different characteristics and applications based on the used nanofiller [20][21][22][23][24]. PMMA is already widely used in form of thin film for the production of different types of electrical and optical devices [25,26], the preparation of superhydrophobic and antireflective glass surfaces [27], as well as the preparation of protective coatings when mixed with inorganic fillers [28], thanks to the ability to tailor its properties depending on the synthesis method and the surface modifications [29].…”
