Crystallization polymer

WebCrystallization process (nucleation and growth) has a great impact on the crystal structure and shape during nanoparticle synthesis. The LaMer theory and Sugimoto model can be used to study the kinetics of nucleation and growth mechanism of nanomaterials (Sugimoto, 2007; Mehranpour et al., 2010 ). WebCrystallization kinetics of polymers and polymer electrolytes is an attractive area for researchers because it has a direct relation to the structure and property of the polymeric materials. The process where an ordered (crystalline) phase is produced from a disordered amorphous phase is referred to as polymer crystallization.
