Charge and chaotropicity appeared crucial, and adjusting these factors led to the very different behavior of the colloidal system. LCST of PNIPAM in an aqueous solution decreased linearly with the rise of KCl concentration (1.2 °C drop for 0.1 M) . Simultaneously, the attachment of NIPAM oligomers to nanoparticles decreased LCST, which was even enhanced if the oligomer was shorter than 18 monomers . Eventually, Humphreys et al. showed that LCST for around 120 nm-SiO2 NPs grafted with PNIPAM decreased linearly with increasing
