Abstract

In this critical review chapter, the authors explain the development of composite films of Barium Titanate (BaTiO3) and Poly (methyl methacrylate) prepared by solution casting technique. Different weight percentage composition of BaTiO3 has been selected to find out the best optimization condition for further investigation and correlate the results. The structural properties have been carried out at room temperature using XRD. Efforts have been made to correlate the results with investigated XRD results of pure BaTiO3 and its composites as observed by other workers at room temperature. The flow of experimental work and microscopic images are explained.

Introduction

The main focus of this chapter is to familiarize the nanostructures materials [ BaTiO3 (Barium Titanate) + PMMA (Poly Methacrylate) + TiO2 (Titanium Oxide) ] for energy storage (embedded capacitor and super capacitor) in our case. We also show how the hierarchical strategy has been adopted by scientist in the area of energy storage device and structural applications. The structural properties have been carried out at room temperature using XRD (X-ray powder diffraction). The average crystallite size of the BaTiO3 (Barium Titanate) particles in the composite films has been found to be lies in between ~ 20 - 30nm. It has been found that the peak intensities increases with increasing the wt. % of BaTiO3 in the composite films. The XRD (X-ray powder diffraction) analysis revealed that the addition of TiO2 has played a crucial role to enhance the crystalline nature of the composite films at room temperature. Normally the value of percentage of Barium titanate varies from zero to fifty (0 to 50), which means by keeping the weight percentage of Titanium oxide and poly methacrylate as constant, also the ambient condition throughout the experiment also fixed.

During last one decade, the advance research work has been carried out on pure BaTiO3 (Barium titanate). Various elements from alkaline earth metal group (such as Ba and Sr etc) and different metal oxides [such as TiO2 (Titanium Dioxide or Titania), BaTiO3 (Barium Titanate), ZnO (Zinc Oxide), SnO (Tin (II) oxide / Stannous Oxide) and PZT (Lead zirconate titanate) etc] have been selected by researchers and numerous group. They have been used in various dielectric, ferroelectric, switching, pyroelectric, optoelectric and piezoelectric applications (Schmidt, H., 2000; May, Gary S., 2007; Lim, J. B., 2008; Morse, Daniel E., 2011; Bruley, John, 2013; Chocat, Noemie, Multimaterial, 2012; Collins, David E., 1999). These metals and elements have well known properties of electrical, structural, thermal, dielectric, electronic, ferroelectric, and morphological (Bhalla, Amar S., 1989; Bhattacharya, Swapan, 2007; Chinchamalatpure, Vijay Ramkrishna, 2010; Zhang, Tianshui, 2014; Cross, L. Eric, 1989). Still there are some problems in addition to these materials lie difficulties to find out the electrical, thermal and physical stability. One of the main problems is its fragile nature.
