TGA and DSC analysis of vinyl ester reinforced by Vetiveria zizanioides, jute and glass fiber

Abstract

Although there are many procedures of analyzing a material, this paper deals with TGA and DSC analysis processes. The purpose of TGA and DSC analyses are to determine physical properties of respective materials. TGA or Thermogravimetric analysis is done for determining the change in physical and chemical properties. Although both of TGA and DSC analyses deal with temperature, TGA analysis provides supplementary and complementary information regarding DSC analysis. In TGA analysis, the change of properties is function of temperature with heating rate as constant or as a function of time with constant temperature (and/or constant mass loss). It provides information about physical phenomena, such as second-order phase transitions, along with characteristics like desorption, sublimation, absorption, and vaporization. DSC analysis is that the difference in the amount of heatrequired to increase temperature of a sample and reference is measured as a function of temperature. TGA provides information regarding physical properties such as vaporization, sublimation, absorption, adsorption and chemical properties like chemisorptions, desolvation, decomposition. Similarly DSC analysis provides information regarding Transition temperatures, glass transitions, Polymorphic transformation.
