| Popis: | Density functional theory has been used to describe the ordering phenomena of amorphous A-B diblock copolymers. The resulting formalism was then used to study the ordering of a symmetric diblock copolymer to the lamellar morphology for values of χN above the microphase separation transition value. The number of statistical segments per diblock copolymer chain is denoted by N and χ is the Flory interaction parameter. Three distinct regimes for the N dependence of the domain spacing D are identified. The distinct features of the microscopic density profiles in the various regimes are discussed |
