摘要

Abstract

The self-consistent field theory has been employed to numerically study the response of bi-disperse flexible polyelectrolyte (PE) brushes grafted on an electrode to electric fields generated by opposite surface charges on the PE-grafted electrode and a second parallel electrode. The numerical study reveals that

under a positive external electric field

the shorter and negatively charged PE chains are more responsive than the longer PE chains in terms of the relative changes in their respective brush heights. Whereas under a negative external electric field

the opposite was observed. The total electric force on the grafted PE chains was calculated and it was found that

under a positive external electric field

the magnitude of the total electric force acting on one shorter PE chain is larger than that on one longer PE chain

or vice versa. The underlying mechanism was unraveled through analyzing the total electric field across the two oppositely charged electrodes.
