Tunable Nanoparticle Stability in Concentrated Polymer Solutions Based on the Temperature Dependent Solvent Quality |
| 초록 |
The ability to control the degree of particle dispersion in polymer soutions has been a long-standing subject in colloidal science. While a generally accepted principle is that non-adsorbing polymers can induce depletion attraction, which is mostly temperature independent, the effects of adding adsorbing polymers are still poorly understood. In this study, we investigated the effects of adsorbing polymer on the temperature-dependent stability of nanoparticles. It was found that a poor solvent for polymer could drive adsorbed polymers to leave the particle substrate and return to the bulk solution due to complicated interaction with surface, while the loss of the steric layer causes the nanoparticles to aggregate at elevated temperatures. |
