Crystallinity - Wikipedia

WebCrystallinity means the degree of regular and structural order in a material or a molecular structure. Crystalline materials have long-range order in their structure. Basically, crystallinity is a common polymer morphology. When the crystallinity of a structure is low, we can say that it is more amorphous. WebCrystallinity can be accurately measured by X-ray diffraction and less accurately but simply by specific gravity. The properties of PCTFE vary with the degree of crystallinity.
