Highly Extended Conformation of Polyelectrolytes Incorporated into Hybrid Threadlike Micelles Studied by Small Angle Neutron Scattering

“…The solid line in Figure represents the particle scattering factor of a rigid rod 10 with length L and an r value of 200 and 2.3 nm, respectively. The broken and dotted lines represent scattering factors of wormlike cylindrical particles with the same L and r values, but with persistence lengths, λ, of 10 and 30 nm, respectively. Because the agreement between the solid line and the obtained P 1 ( q ) appears reasonable across the entire q range, we conclude that the polyelectrolytes are crowded into the hybrid threadlike micellar interior with high confinement of r = 2.3 nm, and that the conformation of the polyelectrolytes in the micelle is extended, with a length greater than 200 nm, as schematically depicted in Scheme .…”
