𝟐𝟎 °𝐂, 𝐰𝐚𝐭𝐞𝐫 -44.8 ± 7.9 -3. The impact of various ions and ionic strengths on the conformation of PNIPAM was studied extensively. The Hofmeister series describes how different ions influence the solubility and structure of macromolecules, so-called "salting-out" and "salting-in" effects. PNIPAM chains were expected to contract in the presence of K⁺, enhancing the "closed" conformation. The higher values of electrophoretic mobilities at 40 °C compared to 20 °C strongly accorded with the previous conclusions, i.e., closed conformation at HT enabled faster movement. Humpreyes et al. studied the effect of various salts on PNIPAM-stabilized particles. In their case, µe changed in a similar way as in our experiments. They measured -
