Helical structures formed from an amorphous, achiral ABC triblock terpolymer |
| 초록 |
We present the experimental visualization of the three-dimensional (3D) helical morphologies of a polystyrene-block-polybutadiene-block-poly(methyl methacrylate) triblock terpolymer (SBM) using transmission electron microtomography. Our results uncovered a left-handed (and to a similar degree, right-handed) double helical structure composed of polybutadiene (PB) helical microdomains around polystyrene (PS) cores. The addition of short polystyrene chains into the PS cores by solution blending was found to be essential to control the pitch of the helix. |
