Name: Study of Thermal stability of organic–inorganic composites by Thermal Gravimetric Analysis (TGA)
SKU: STEM-ACT-0042-WXH
Rating: 5 (1 reviews)

Introduction

For compensating the thermal, mechanical, and other properties of the organic polymeric materials, inorganic fillers are added into the polymer formulations to form organic–inorganic composites. The property of a composite material, certainly, is depending on the properties of the individual components. On the other hand, the phase morphology and interfacial properties of the composites also significantly influence the properties of the composite materials.

Principle

Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. This measurement provides information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and solid-gas reactions (e.g., oxidation or reduction).

Applications

• Thermal characterization of polymers.
• Determination of the composition of alloys and mixtures.
• Determining the purity and thermal stability of both primary and secondary standards.

Procedure

TGA analysis is performed by gradually raising the temperature of a sample in a furnace as weight is measured on an analytical balance that remains outside the furnace. Thermogravimetric analysis instrument measures the changes in a sample's weight in a particular temperature by enclosing the sample in an oven.
