I will introduce a case study on the adsorption and desorption of polymers using surfactants.
We would like to introduce a case where SDS was added at concentrations of 0%, 1%, 3%, and 5% to dispersions of colloidal silica with and without 1% PVP adsorbed. When SDS was added to the colloidal silica with 1% PVP, the Rsp value decreased as the concentration increased, approaching the Rsp value of the dispersion containing only colloidal silica. It was suggested that PVP and SDS have a stronger binding force than silica, and that SDS has the property of chemically bonding with PVP, causing PVP to detach from silica. 【Case Summary】 ■ Experiment - SDS was added at concentrations of 0%, 1%, 3%, and 5% to dispersions of colloidal silica with and without 1% PVP adsorbed. ■ Results - The Rsp value decreased when SDS was added to the colloidal silica with 1% PVP. - It approached the Rsp value of the dispersion containing only colloidal silica. *For more details, please refer to the PDF document or feel free to contact us.
