Nonlinear electric response of polyampholytes
(2003) In Theoretical Chemistry Accounts 110(3). p.126-129- Abstract
- The behavior of polyampholytes (PAs) in electric fields is investigated by Monte Carlo simulations. In bulk it is found that the response of the PA depends on the charge sequence. For small repeating units of positive and negative charges the response is linear, while bigger units results in a nonlinear response in both the induced dipole moment and the resulting polymer conformation. This is reflected in how PAs modify colloidal suspensions, and while PAs always decrease the repulsion between charged colloidal particles, some net-neutral PAs can even induce an effective attraction between the colloidal particles.
