Numerical and Experimental Analysis of Optical Property of Polymers (PEG & PPG)

Abstract

Refractive index plays a vital role in many branches of physics, chemistry and biology. In optics, the refractive index or index of refraction n of a material is a dimensionless number that describes how light propagates through that medium. Polymers are becoming increasingly attractive for a variety of optical applications such as lenses, optical circuits, optical fibers, antireflective films and coatings, optical adhesives, LCD displays, waveguides, UV-reactive inks and varnishes. There are many standard mathematical methods available to measure the Refractive Index. In the present study, Abbe refractometer is used for experimental measurement of refractive Index. In this paper, the refractive index of Polypropylene Glycol (PPG 400, PPG 4000) in toluene and aqueous mixture of Polyethelene Glycol (PEG 200) have been estimated for different concentrations (2%, 4%, 6%, 8% & 10%) at 303K and these experimental values are compared with theoretical values obtained by using various mathematical methods like Lorentz-Lorenz equation, GladstoneDale equation, Newton’s equation, Arago-Biot(AB) equation, Heller equation and Weiner equation. Average Percentage Error (APE) technique is used to match the most accurate method with experimental method. Comparison of evaluated theoretical refractive indices with experimental values reveal the nature of interaction between component molecules in the mixtures.
