Abstract

The microscopic network structure transitions of a conjugated polyelectrolyte (Poly[2,6-(4,4-bis-potassium butanylsulfonate-4H-cyclopenta-[2,1-b;3,4-b']-dithiophene)-alt-4,7-(2,1,3-benzothiadiazole)], CPE-K) hydrogel were explored with a combination of scattering methods. Small-Angle Neutron Scattering (SANS) illustrates a novel, hierarchical structure formed by the gelation of CPE-K in water in the semi-dilute regime. SANS and X-ray scattering illustrate the gradual melting of the gel structure with increasing temperature through the dissolution of ionic aggregate crosslinks.
