WebJun 16, 2016 · Once again, when we have segregation, the segregation also goes to the boundaries. Now, the way the crystallization process develops with respect to the polymers, it's a chain folding process. And depending upon the complexity of the polymer that we're dealing with, we can affect the ability of that particular polymer to crystallize. 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 ).
