Instead of the familiar sequence of morphologies, a broad multiphase window centred at relatively high concentrations (ca. 50-70% block copolymer) truncates the ordered lamellar regime. At higher epoxy concentrations wormlike micelles and eventually vesicles at the lowest compositions are observed. Worm-like micelles are found over a broad composition range (Fig. 67). This morphology is rare in block copolymer/homopolymer blends [202] but is commonly encountered in the case of surfactant solutions [203] and mixtures of block copolymers with water and other low molecular weight diluents [204,205]. [Pg.215]

This chapter is organized as follows. Section 6.2 is concerned with experiments on binary block copolymer/homopolymer blends, Section 6.3 deals with experiments on ternary blends containing a block copolymer and in Section 6.4 experiments on binary blends of block copolymers are reviewed. Theory for the corresponding type of blend is discussed successively in Sections 6.5 to 6.7. Finally, experiments on thin films are discussed in Section 6.8, separately from the work on bulk blends, in keeping with earlier chapters. [Pg.332]

Floudas et al. (1997) studied theoretically and experimentally microphase segregation in block copolymer/homopolymer blends for an asymmetric diblock copolymer and homopolymer concentrations of less than 25 %. It was observed that the minority phase could solubilize only a small amount of added homopolymer. The addition of higher amounts resulted in the formation of nonequilibrium structures. Theoretical predictions in the strong segregation limit showed that (xN)c,... [Pg.458]

In block copolymer/homopolymer blends there is some evidence for lamellar systems (Quan and Koberstein, Macromolecules. 1987) that the homopolymer is localized in the center of the microdomain. This effect would lead to the kind of diffusion resistance that you have observed, that is, a greater resistance than that caused simply by dilution by the second component. Secondly, the solubility of the homopolymer in the microdomains falls off rapidly when its MW is about 1/2 that of the like copolymer sequence. In your case, however, you still get diffusion up to the case of equal MW s, This may be related to your conclusion that your system behaves as if it is in the weak segregation limit. [Pg.385]

SAXS measurements have also been useful in studies of the morphology and phase behavior of block copolymer/homopolymer blends. SAXS data on PS blends with SB diblock copolymers showed the presence of microdomains, which disappeared as the order-disorder transition was approached with increased temperature [162]. The order-disorder transition and the order-order transition (change in gyroid to cylinder morphology) was investigated with SAXS for PS/SI diblock copolymer blends [163]. The interfacial thickness of PS/PMMA samples with... [Pg.285]
