Thermogravimetric analysis of sponge chitins in thermooxidative conditions

Abstract

Structural aminopolysaccharide chitin possesses diverse physicochemical properties which are important principal for use of this biopolymer in technology. Recently, special attention has been paid to the thermostability of chitin because of its potential application in hydrothermal synthesis with the aim to obtain novel nanostructured metal oxide-based composite materials. It was shown that chitin is still stable in the range of temperatures between 100 and 400 °C. Here, chitins from different origins have been studied with respect to investigate their thermostability using thermogravimetric analysis.
