, respectively (cf. Figure in ). The authors explained that the dispersion was sterically stabilized in water at LT. At HT, the brush layer collapsed, and polymer-polymer interactions dominated. Thus, the particles were electrostatically stabilized due to a significant increase in the underlying surface charge. After adding the salt, they correlated changes in LCST temperature and mobilities. However, they could not observe a full "open" to "closed" transition as their particles aggregated upon the addition of salt at HT. We noticed aggregation only at the highest salt concentration and HT, as evidenced by DLS measurements.
