Change in
end-to-end distance of doubly-attached chains |
|
Squared end-to-end
distance of doubly-attached chains, Rd2,
normalized by mean squared end-to-end distance, <Rd2>,
is investigated to be decreasing with attachment sequence index. The
higher sequence index, the later this chain gets doubly-attached. |

Extension
of doubly-attached chains along z
direction |
|
By investigating
highest z position of doubly-attached chain, they are found to be
extending along z direction with attachment sequence index
increasing. |

Diffusion from
melt to surface reduces upon formation of brushes |
|
Comparing systems with
and without reactive wall, we notice diffusion from center of the
system to wall surface is significantly reduced.
In the plot below, dt refers to the time (in terms of Monte Carlo
steps) for one chain to move from center of the system to wall surface.
