CID

CID, or Crystallinity Index, measures how ordered the molecules are within a material, especially in polymers or biopolymers like cellulose. Think of it as a score indicating how tightly packed and organized the molecules are: higher CID means more crystalline (structured and orderly), while lower CID points to more amorphous (disordered) regions. This affects properties like strength, transparency, and how the material interacts with chemicals or water. By assessing CID, scientists can predict and tailor a material's performance for various applications, from industrial uses to biomedical devices.
