Novel Analysis of Inorganic-Organic Composites using Raman Microscopy

Abstract

Recently inorganic/organic composites, such as calcium carbonate and water-soluble organic polymer with fine and complex structures have been actively advancing. Therefore, it is necessary to develop a novel analytical method for these materials. In order to solve the problem, a comprehensive non-destructive methodology for the simultaneous quantitative analysis of the calcium carbonate crystal phases in their binary mixtures and organic polymers was developed, based on the use of a Raman microscope. In this method, relative error of aragonite was on a level of X-ray diffraction, while that of organic polymers was 30%.
