Crystallinity

1. Degree of structural order in a solid (MatPortal, MaterialsMine). 2. Crystallinity is defined as the degree of structural order of molecules in a polymer, with higher crystallinity leading to lower permeability of polymer composites. It influences the mass transfer of gases or aromas in semicrystalline polymers, where the amorphous phase allows permeation while the crystalline phase is impermeable. (ScienceDirect, AI generated definition based on: Handbook of Chitin and Chitosan, 2020). 3. Crystallinity refers to the degree of structural order in a solid. In a crystal, the atoms or molecules are arranged in a regular, periodic manner. The degree of crystallinity has a large influence on hardness, density, transparency and diffusion. (Wikipedia). 4. Crystallinity generally refers to the degree of crystalline regions composing a material. (ScienceDirect, Durability and Life Prediction in Biocomposites, Fibre-Reinforced Composites and Hybrid Composites, 2019).
