Mechanical Strength Analysis of Acrylic Films Using Acoustical Technique | Chapter 7 | Theory and Applications of Chemistry Vol. 4

In order to improve the mechanical properties of acrylic films, Poly methyl-methacrylate (PMMA)/ Aluminum oxide (Al 2 O 3 ) films are prepared following solution casting technique. The mechanical behavior of prepared films has been analyzed by employing Ultrasonic Pulse Echo method. The morphology of films is examined via XRD and SEM analysis. The synergetic effect is observed in films from obtained ultrasonic data. The elastic modulus is calculated and compared for better utilization. Author(s) Details Dr. A. R.

Ultrasonic, Dielectric and thermal investigation of PMMA / Fe2O3 Films | Chapter 05 | Advances in Applied Science and Technology Vol. 7

Solid polymer metal oxide films containing Poly (methyl-methacrylates) PMMA/Ferric oxide Fe 2 O 3 are synthesized following solution cast technique. Complexation and particle size are determined by XRD and SEM analysis. Ultrasonic and Dielectric characterization have been done by using Ultrasonic Pulse Echo method and LCR meter respectively. The dielectric behavior of PMMA/ Fe 2 O 3 films has been studied as a function of concentration, and at lower frequencies over the range 100 Hz - 25 KHz. A 7:3 PMMA/Fe 2 O 3 film have been found to posses optimal conducting and optical properties. The ultrasonic velocity is also found to be minimum in same film which may be attributed to maximum dissociation with least absorption in polymer matrix. Addition of Fe 2 O 3 thermally stabilizes PMMA matrix. Author(s) Details Dr. A. R. Bansod Acoustical Research Lab, PG Department of Physics, RTMNU, Nagpur, 992302440, India. Dr. O. P.

An Effect of Precursor Concentration on ZnO Thin Films Prepared by Dip Coating Method | Chapter 08 | New Insights on Chemical Research Vol. 1

Zinc Oxide (ZnO) thin films have been successfully coated onto glass substrates at various solutions concentration (0.1 M, 0.2 M and 0.3 M) by Low cost SILAR coating technique. The film thickness was estimated using weight gain method and it revealed that the film thickness increased with solution concentration values. The prepared film structural, morphological and optical properties were studied using X-ray diffraction (XRD), scanning electron microscope (SEM) and UV-Vis-NIR spectrophotometer respectively. The structure of the films were found to be hexagonal structure with polycrystalline in nature with preferential orientation along (002) plane. X-ray line profile analysis was used to evaluate the micro structural parameters such as crystallite size, micro strain, dislocation density and stacking fault probability. The value of the crystalline size is increased by increasing the concentration of the solution. The average crystalline size was estimated at in the range of 26 nm to...

A Short Review on the Synthesis of Electrodeposited Thin Films | Chapter 07 | New Advances in Materials Science and Engineering Vol. 1

Nanostructured thin films have been prepared by using various deposition techniques. The obtain films showed unique physical, optical and electrical properties. Therefore, these materials could be used in solar cell, optoelectronic, laser and sensor devices. In this work, the preparation of metal chalcogenide thin films by using electrodeposition method was reported. Electrodeposition method has many advantages such as low temperature is required, low cost investment, can produce desired film over large surface area and can control the thickness of the film. Characterization of obtained films was investigated by using various tools. The band gap values are in the range of 1.15 to 2.19 eV. Annealed films indicated excellent crystallinity if compared to as-deposited films.

Cu4SnS4 Thin Films: Advances in Research | Chapter 4 | Theory and Applications of Chemistry Vol. 2

Cu 4 SnS 4 thin films have been synthesized using electro deposition, chemical bath deposition and Thermal evaporation method. XRD confirmed that these films have polycrystalline in nature with orthorhombic structure. The band gap was determined using UV-Visible spectrophotometry data, about 1.2 to 1.94 eV. The obtained films could be used in solar cell application due to appropriate band gap and good photo response behavior.
