Abstract

Using 3-dimensional cell dynamics simulation, we demonstrate
that the tetragonal phase of cylinder forming diblock copolymers can be induced
on both topographical and chemical patterned substrates. The results
quantitatively describe the different effect of both substrates on the degree of
imperfection in the tetragonal phase observed in recent experiments [Xu, J.et al.
Soft Matter 2011, 7, 3915]. Comparative analysis of the structural evolution for
different thermal noise level in square, rectangular and diamond-shape lateral
confinements is performed.
