Abstract
|
The fibrillar poly(3-hexyl thiophene) single
crystals were prepared from dilute solutions of toluene,
xylene, and anisole (0.01 wt%), and were investigated
from the perspective of structural properties. Next, the
rectangular and hexagonal poly(ethylene glycol) single
crystals were developed from the dilute solutions and
molten thin polymer films. The developing methodology
used for all growth systems was self-seeding. The dimensions of fibrillar and rectangular/hexagonal single crystals
ranged from several nanometers to some microns. Random
single-co-crystals were also grown from dilute solution
(0.018 wt% in amyl acetate) of crystalline–amorphous
diblock copolymers and homopolymers. The small-angle
X-ray scattering, grazing incidence wide-angle X-ray
scattering, and atomic force microscopy analyses were
employed to characterize prepared grained samples. The
incident X-ray experiments demonstrated highly ordered
and lamellar crystalline structures.
