Слегка глянул по теме - в настоящее время этим продолжают заниматься, только естественно классифицируют это как нано-эффекты, куда же без этого
Вот просто навскидку ссылки на парочку буржуйских статей:
1) T. Grigorova, S. Pispas, N. Hadjichristidis, and T. Thurn-Albrecht 'Magnetic Field Induced Orientation in Diblock Copolymers with One Crystallizable Block' Macromolecules 2005, 38, 7430-7433
Using wide-angle X-ray scattering, we show that diblock copolymers with one crystallizable
block can be oriented by crystallization in a strong magnetic field (B ) 7 T). The resulting structure
consists of a stack of alternating crystalline and amorphous layers of different chemical compositions
with the layer normal being oriented perpendicular to the applied field.

Explicitly, we have shown that
by crystallizing a diblock copolymer in a magnetic field
an oriented, chemically nanostructured material can be
produced.
2) Florian Ebert and Thomas Thurn-Albrecht 'Controlling the Orientation of Semicrystalline Polymers by Crystallization in Magnetic Fields' Macromolecules 2003, 36, 8685-8694
As reported previously, strong orientation of crystalline chain segments perpendicular to the magnetic
field can be achieved. We present a method to determine the degree of orientation from the wide-angle
X-ray scattering pattern in a quantitative way. The degree of orientation strongly depends on the
crystallization temperature, allowing for nearly perfect orientation only at low supercooling.
прикрыли мою "лавочку". Матерал обещает быть интересным.
