Phase Morphologies of a Melt of Heterogeneous Dendritic Polymers |
| 초록 |
Equilibrium phase morphologies of two different dendritic block copolymer melts are calculated and compared. These copolymers have a pitchfork-like architecture and consist of three distinct blocks that correspond roughly to the handle, the connecting middle dendron structure, and the attached tines of a pitchfork. The first melt considered consists of a copolymer that has a simple Y-junction middle block, and it connects the handle to two tines. The second is similar except its dendritic middle block branches twice to connect to four tines. All calculations are done for incompressible melts in the context of self-consistent mean-field theory. We find that several morphologies compete for stability depending on the architecture and lengths of the blocks as well as their incompatibilities. As many as four stable two-dimensional phases appear in the phase diagram including: columnar square, rectangular and hexagonally packed structures. |
