Transition from polythiophene-based one-dimensional nanofibers to spherical clusters in ultrafiltration

Abstract

We report the behavior of one-dimensional polythiophene-based nanofibers in solutions passing through the nanopores under a flow field. Under a strong flow field, a fiber-to-cluster transition can be observed when the nanofiber solution concentration is above a critical value. The Zimm time and the passing time of the nanofibers are compared to explain the way the nanofibers pass through the nanopores under different flow fields.
