Polymer toner surface tension

WebSurface tension of polymers can be divided into two components, polar (𝛾𝑃) and dispersion (𝛾 ) to account the type of attraction forces at the interfaces. The chemical constitution of the surface determines the relative contribution of each component to surface tension. The polar component is comprised of various WebFeb 25, 2011 · Surface Tensions of Molten Polymers as a Function of Molecular Weight and Temperature. - Volume 248.

WebThe surface tension is a direct measure of the intermolecular forces at the level of the surface. Due to surface tension the tendency of liquids is to reduce their energy as much as possible, then to form drops. The surface tension varies with the temperature, the composition of the flow and the interactions between the alloy of the substrates.
