Resumen:
Block copolymers are macromolecules composed of at
least two blocks of different monomers.
They often exhibit unique and useful properties in
solution and in the solid state as a
consequence of a microphase separation produced by
thermodynamic incompatibility of the
blocks. Domains obtained show different morphology
(spheric, cylindric or lamellar, among
others) as a function of the volume fraction and the
relative length of each block as well as the
nature of the blocks involved. On the other hand,
defects associated to some morphologies can
be modified by thermal treatments. In this work we
present the morphological characterization
of
siloxane-based di-block copolymers by Transmission Electron Microscopy (TEM).
