Thermal properties, polymeric materials differential scanning calorimetry

A very commonly used method to investigate thermal properties of polymeric materials is differential scanning calorimetry (DSC). Many studies were conducted based on thermal analysis. The DSC is defined as a method in which the rate of heat flow, to which the sample is exposed, is measured in function of time or temperature, while the sample temperature (in defined atmosphere) is programmed. The DSC method allows for obtaining measurable information regarding phase transition and kinetic parameters of composite materials. 

The more common techniques used to analyze thermosets and composites are thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), which can determine the thermal properties and also the best conditions for application of the materials. These techniques can be apphed to polymers to determine their specific heat, degree of polymerization, flanunability, degradation, cure, glass transition temperature (Tg), and other characteristics. Analysis of composites should consider the behavior of each component, including the matrix, reinforcement, plasticizers and fire retardants.
