Webwhat is meant by crystallinity? Crystallinity 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. WebNov 3, 2024 · This study examined the effects of micro- (crystallinity) and macro (orientation)-crystalline properties of graphite on the initial efficiency, discharge capacity, and rate performance of anodic materials. Needle coke and regular coke were selected as raw materials and pulverized to 2–25 μm to determine the effects of crystalline properties on …

Crystallinity is a physical property of a solid that acts like a crystal. The degree of crystallinity of a crystal has a big influence on hardness, density, transparency and diffusion. Crystallinity can be measured using x-ray diffraction, but calorimetric techniques are also commonly used. Examples would include ...
WebThe percent crystallinity is directly related to many of the key properties exhibited by a semi-crystalline polymer including: • Brittleness • Toughness • Stiffness or modulus • Optical clarity • Creep or cold flow • Barrier resistance (ability to prevent gas transfer in or out) • Long term stability Applications where knowing the value of the … WebCrystallinity refers to the degree of structural order of a solid. In a crystal, the arrangement of atoms or molecules is consistent and repetitive. Many materials such as glass ceramics and some polymers can be prepared in …
WebThe concept of crystallinity is discussed not simply in the narrow sense of degree of crystallinity but in the broader sense, which involves the whole fine structure of cellulose. With respect to crystallinity in the latter sense, there are four main factors, each involving a mean value and a distribution of values, both mathematical and spatial.
