SELF-ASSEMBLY OF GYROID-FORMING BLOCK COPOLYMERS CONFINED IN CYLINDRICAL NANOPORES
The self-assembly of block copolymers has attracted great scientific interest due to the ability of forming a variety of ordered microstructures at 10100nm scale.1 For the simplest case of diblock copolymers (DBC), which are linear polymers composed of two incompatible subchains (A and B block), their phase behaviour is controlled by the competition between the A-B repulsion and chain connectivity. The equilibrium ordered structures that can be formed in DBC melts including body-centred cubic array of spheres, hexagonally packed cylinders, bicontinuous network structure called gyroid phase and alternative lamellae, depending on the volume fraction of the components.2 Among all of these ordered structures, gyroid phase has gotten much attention due to its complex structure. Gyroid phase, known as embedded triply periodic minimal surface with triple junctions, has special novel applications in fabricating nano-devices such as porous materials with high contact surface, high conductivity nanocomposites and so on.3
