Crystalline Morphology of Weakly Segregated Block Copolymers

1 Crystalline Morphology of Weakly Segregated Block Copolymers 

If we suppose the conformation of crystalline and amorphous blocks in the lamellar morphology from a thermodynamic viewpoint, random coil conformations are most favorable for amorphous blocks and perfect crystals with no chain folding for crystalline blocks. However, these two 

DlMarzio et al. [78] and Whitmore and Noolandi [79] theoretically predicted an equihbrium lamellar morphology formed in crystalline-amorphous diblock copolymers. The long period of the lamellar morphology L, that is, a sum of crystalline layer thickness and amorphous layer thickness, is expressed by a scaling form
