The structure of polymer materials can be described at different length scales, from sub-nm up to macroscopic length scales. It can be divided into two types: microstructure morphology and macrostructure morphology. The microstructure of a polymer is related to the physical arrangement of monomer residues along the backbone of the chain and it determines its macroscopic physical and mechanical properties, such as the crystallinity, the glass transition temperature, or microphase separation phenomenon. On the other hand, the macrostructuremorphology is related to the interactions between the polymer chains. Both features are very essential and useful, playing a major role in determining the physical and chemical properties of a polymer.
