You can evaluate the crystallinity density and amorphous density of a polymer blend by using Differential Scanning Calorimetry (DSC). The thermogram produced by a DSC scan will give you information about the melting point, glass transition temperature, and other thermal properties of the sample. You can then use this data to determine the crystallinity density and amorphous density of the polymer blend.
SIR, I have the DSC DATA, but from the data we can calculate the crystallinity but, my question is related to calculate the percentage of crystalline density and amorphous density.
