Matsen, M. W. (2007) Polydispersity-induced macrophase separation in diblock copolymer melts. Physical Review Letters, 99. p. 148304. doi: 10.1103/PhysRevLett.99.148304
Abstract/Summary
The effect of A-block polydispersity on the phase behavior of AB diblock copolymer melts is examined using a complete self-consistent field theory treatment that allows for fractionation of the parent molecular-weight distribution. In addition to observing the established shift in phase boundaries, we find the emergence of significant two-phase coexistence regions causing, for instance, the disappearance of the complex phase window. Furthermore, we find evidence that polydispersity relieves packing frustration, which will reduce the tendency for long-range order.
