摘要
Block copolymers made of polystyrene and fluorinated blocks represent a new class of polymers with a very strong incompatibility between the two blocks. They exhibit new stable block copolymer mesophases which are not considered in the phase diagrams of diblock copolymers in the strong and super-strong segregation regime. The solid-state structures of two polymers with different compositions are characterized by synchrotron small-angle X-ray scattering and transmission electron microscopy, thus proving the existence of a quadratically perforated layer phase and a 2D phase of sanidically degenerated cylinders.
