The micellar phase of amphiphilic block copolymers can be easily changed by their external conditions as its mass fraction of hydrophilic/phobic. Therefore, the micellar structures can be controlled by mass ratio of their consisted chain or mixing with another block copolymer. However, for an amphiphilic block copolymer with a high molecular weight to change its shape into a vesicle is very rare and still has not been fully exploited yet. While the mixture system of two kinds of block copolymers is an easy and different mass fraction of the hydrophilic moiety. In addition, the small angle neutron scattering (SANS) intensities was reproduced by the model functions. The SANS intensities showed that, depending on the concentration of the polymer with a random coil structure transformed into spheres, cylinders, and vesicles. The self-assembled structures of block copolymers can provide a broad spectrum of potential applications in nano-building blocks and drug delivery systems. |
