Thermal Analysis of Lignocellulosic Materials. Part II. Modified Materials

Abstract

Abstract Thermal analysis is a group of techniques in which a physical property of a substance is measured as a function of temperature while the substance is subjected to a controlled temperature program. The output of thermal analysis represents data predominantly in the form of curves characteristic for a particular chemical substance or a mixture of substances. Changes in latent heat in a chemical substance are detectable by differential thermal analysis (DTA) or by differential scanning calorimetry (DSC). Progressive weight loss is detectable by thermogravimetry (TG) or differential thermogravimetry (DTG). Progressive changes in certain mechanical properties are detectable by thermomechanical analysis (TMA). Many other thermoanalytical techniques are available, but are used appreciably less often.
