Combining Brownian dynamics simulations and self-consistent field theory
we demonstrate that unsegregated chains
clusters
single micelles or structures where several small micelles are strung together by the backbone can be obtained by adjusting the architectural parameters of core-shell comb-like chains.
Combining Brownian dynamics simulations and self-consistent field theory
we demonstrate that the architectural parameters of core-shell comb-like chains have a decisive influence on their final self-assembled conformations. When the ratio of hydrophilic and hydrophobic segments is
$$N_{{\rm{g
g}}} : N_{{\rm{g
r}}} = 3 : 1$$
http://notExist.jpg
no core-shell structure is observed
and unsegregated chains or clusters are substituted. When
$$N_{{\rm{g
g}}} : N_{{\rm{g
r}}} = 3 : 2$$
https://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=46966282&type=
or
$$3 : 3$$
https://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=46966303&type=
the core-shell comb-like chains can be assembled into single micelles or structures where several small micelles are strung together by the backbone
which is similar to the pearl-necklace structure formed by the polyelectrolytes in poor solvent. With the increase of backbone length or grafting density
the probability of forming single micelles becomes lower
but the structures of two
three or more small micelles strung together are more observed. Our results indicate how to obtain the desired self-assembled structures of core-shell comb-like chains by regulating the architectural parameters
which could provide insights for the optimization of molecular design in various applications.
