DSC can be also used to determine the Tg (glass-transition temperature).

In general, it is used to characterize the thermal transition temperatures, enthalpies of transitions and the crystallinity of a material.

For composites, DSC can be used to study the effect of fillers addition on thermal properties of the matrix. Concerning the polymer crystallization, two factors are influenced by the interface modifications: (i) the nucleating effect of fillers that impacts crystallization kinetics, and (ii) the steric hindrance that alters the growth of crystals and could inhibit crystallization.

The glass transition temperature of nano composites can be studied. degree of crystalinity we can. It is a tool to measure the amount of energy need for each phase in heating or cooling of composite.

Besides the abovementioned answers, you can produce phase diagrams for your materials' system.

DSC analysis covers determination of:

· Transition temperatures

· Enthalpies of fusion and crystallization

· Melting extrapolated onset temperature, Melting extrapolated end temperature, and Melting peak temperature

· Crystallization extrapolated onset temperature, Crystallization peak temperature, Crystallization extrapolated end temperature

I have attached DSC standard. I hope it would be useful.

Dear all, DSC is a powerfull tool to assess the compatibility of blends and heterophases materials. My Regards

Hi;

Differential Scanning Calorimetry (DSC) is used to study the thermal transitions of materials to determine properties such as glass transition temperature (Tg), crystallization temperature (Tc) or melting temperature (Tf). The result of a DSC is usually presented in the form of a graph showing heat flow as a function of temperature (or time). Since the sample undergoes phase changes as it is heated, the amount of heat required to maintain the temperature of the sample at the reference temperature will vary as a function of temperature. There are two types of phase changes: exothermic processes (where the sample releases heat) and endothermic processes (where the sample releases heat).

The sample absorbs heat). For example, in an exothermic process such as crystallization, less heat is required to raise the temperature of the sample because the sample releases heat. Conversely, a sample undergoing an endothermic transition, such as the transition from the solid to the liquid phase, will require more heat to maintain the same temperature as the reference because it absorbs energy. DSC is also used to measure its degree of crystallinity. This property is important because crystallinity directly affects several physical characteristics such as permeability, density or melting temperature. In addition, DSC can give indications of the degradation of a polymer, which usually results in a drop in melting point.

With my best regards
