To Study Dispersion Pattern of Nano Filler in Polymer Composite for Radiation Hardened Package

Abstract

Nanocomposite technology is a young material science and plastic nanocomposites are among its first commercial applications. Nanocomposite products improve various properties of many plastics. They are not only used to improve existing products, but also are extending their reach into areas formerly dominated by metal, glass, ceramic and wood. Main focus of this study is the dispersion of nano filler in epoxy resin to produce radiation hardened plastic packaging which can be used as a shielding against a high frequency radiation attack mainly gamma radiation. The study is carried out as part of research project for a development of Radhard Plastic Package for VLSI. It is mainly focused on dispersion pattern of regular sized fillers against nanofillers and combination of both in sample. Good nanofillers dispersion in a polymer resin is crucial for achieving performance. Microscope images are also an important part of the quality control function. Few experiments are carried out and microscopic images are also taken to study dispersion in resin. Small batches using gravity casting method at laboratory with different sizes of same fillers varying from microns to nano and combination of both using compatibilisers to carry out experiments and an exhaustive literature review is also been done to understand the effect on radiation resistance.
