For the first time, self-assembly and non-solvent induced phase separation was applied to polysulfone-based linear block copolymers, reaching mechanical stability much higher than other block copolymer membranes used in this method, which were mainly based on polystyrene blocks.

Spherical and cylindrical micelles are quite common in lipid/water systems. The self assembly of amphiphilic molecules into well defined geometries has been extensively studied and is explained in terms of geometric and packing properties in addition to electrostatic, van der Waals and solvation forces. While macromolecular self assembly may seem more complex than for such small molecule systems, it is actually a simpler physical situation to model. Much can be learned from the combined study of each type of system.In block copolymer/homopolymer blends the scale of the phase separation is restricted to the radius of gyration of the polymer blocks (typically several hundred A). By varying the composition and the molecular weights of the blocks and of the homopolymer, a wide range of morphologies and therefore physical properties can be achieved.

Polystyrene-b-Polylactide (PS-b-PLA) was dissolved in chlorobenzene, and the development of the micro-phase separation morphology in asymmetric PS-b-PLA thin films was investigated by AFM. The thin films were prepared by spinning casting at the speed of 6000 r/min for 60s on Si substrates. We get different morphologies of PS-b-PLA thin film by changing the annealing temperature from 150 °C to 170 °C. In addition, the annealing time influences the morphology of the film. When the annealing time increased from 2 hours to 15 hours and 30 hours, the morphology transformed from parallel to perpendicular to the substrate. By applying temperature gradients, we can control the morphology and orientation of the Block copolymer film self-assembly.
