Transient electric birefringence of segmentally flexible macromolecules in electric fields of arbitrary strength

Article Abstract:

Studies done on the decay of the electric birefringence from the steady-state value to zero when an orienting electric field applied on a macromolecule is switched off is reported. Results reveal that hydrodynamic interaction is vital in describing the relaxation times of a molecule, but amplitudes are not affected by this refinement, which should be an advantage for the application and development of different simplified theories.

Birefringence, deformation, and scattering of wormlike macromolecules under an external agent. Steady-state properties in an electric field

Article Abstract:

The steady-state birefringence, deformation, and scattering of wormlike macromolecules under the influence of an electric field are investigated. The Monte Carlo computer simulation is used to understand the difference between the behavior of broken rod and a wormlike chain.

Birefringence, deformation, and scattering of segmentally flexible macromolecules under an external agent. Steady-state properties in an electric field

Article Abstract:

Research is presented illustrating the relation between electrical properties of macromolecules and their flexibility. It is shown that the deformations and birefringence provide a connection between electric field light scattering and electric birefringence.
