surface properties

The plasma-chemical method of track-etched polyethylene terephthalate membranes surface modification by monomers with different chemical structure was developed. Physico-chemical properties of modified membranes were investigated. The authors showed the possibility of obtaining membranes with the required properties.

In this work, experimental methods used for the evaluation of stability of solids in liquids dispersions, are presented. For the characterization of dispersion components, modern analytical techniques, such as tensiometry, scanning and static turbidimetry, have been applied. The influence of selected surface active substances on the dispersion stability was demonstrated.
