Webcrystalline: [adjective] resembling crystal: such as. strikingly clear or sparkling. clear-cut. 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.
