| Abstract: |
| Investigation of effective parameters such as hydrophobicity and hydrophilicity of nanoparticles and their surface chemistry on the kinetics of adsorption at solid-liquid interfaces is of great importance. In this study, the adsorption dynamics of surface-modified nanoparticles grafted with hydrophilic (propyl chains) and/or hydrophobic (Polyethylene glycol chains) agents on glass surfaces is investigated. It was found that the kinetics of the adsorption is second-order. Also, for environmentally responsive nanoparticles, overshoot phenomenon was observed due to temporary surface oversaturation. |
