Thermoresponsive PNIPAM-Grafted Silica Particles for Modulating Coffee-Ring Effects in Drying Colloidal Droplets

Thermoresponsive PNIPAM-Grafted Silica Particles for Modulating Coffee-Ring Effects in Drying Colloidal Droplets

Thermoresponsive poly(<i>N</i>-isopropylacrylamide)-grafted silica (SiO<sub>2</sub>-PNIPAM) particles were synthesized to control the drying patterns of colloidal suspension droplets. These particles undergo a hydrophilic-to-hydrophobic transition at a lower critical solution...
