| 제목 | Hartree Analysis for Compressible Diblock Copolymers |
| 초록 | We suggest here a Hartree free energy for compressible diblock copolymer systems to study their microphase separation behavior. An approximate Landau free energy previously obtained for the same systems is corrected self-consistently to include the concentration fluctuations effects. It is shown that ΝχcRPA , where N is the total chain size and χcRPA is an effective Flory-type interaction from the compressible Hartree energy, acts the same role of the relevant parameter as in the incompressible version by Fredrickson and Helfand. N-scaling of ΝχcRPA at order-disorder transitions (ODT) and the pressure effects on the fluctuation induced ODT's are discussed. |
