Conventionally, given a solution of dispersed polymer chains, a scaling exponent of 1 is indicative of the dilute regime where the polymer chains do not interact. At around 10 mg/mL, the scaling exponent changes to 1.7 indicating the emergence of polymer interactions at the overlap concentration of mg/mL. As discussed above, the PII-2T/CB solution contains both fibril aggregates and dispersed polymer chains over the concentration range explored here.
