Liquid - polymer equilibrium "contact" distance

In summary, "liquid-polymer equilibrium contact distance" is the distance between a liquid and a polymer material at which equilibrium is reached, and it is determined through various methods such as contact angle measurements, surface energy calculations, and surface tension measurements. This distance is important because it affects the behavior of liquids on polymer surfaces, and it can be altered through methods such as changing surface properties, temperature, or using different liquids.

Hi everyone,

In this paper ( http://pubs.acs.org/doi/abs/10.1021/la962131c ), the authors calculate the surface energy of polymer and the contact angle of various liquids on these polymers using a so-called "liquid - polymer equilbrium contact dsitance". I'm wondering how to calculate such a value ?

Thanks

1. What is "liquid-polymer equilibrium contact distance"?

"Liquid-polymer equilibrium contact distance" refers to the distance between a liquid and a polymer material at which equilibrium is reached, meaning that the liquid molecules are in close contact with the polymer surface and are not able to penetrate or escape from it.

2. How is the "liquid-polymer equilibrium contact distance" determined?

The "liquid-polymer equilibrium contact distance" is determined through various methods such as contact angle measurements, surface energy calculations, and surface tension measurements. These methods help to determine the distance at which the liquid and polymer come into contact and reach equilibrium.

3. Why is the "liquid-polymer equilibrium contact distance" important?

The "liquid-polymer equilibrium contact distance" is important because it affects the behavior of liquids on polymer surfaces. This distance determines the extent to which the liquid can interact with the polymer surface, which can impact properties such as adhesion, wetting, and surface tension.

4. How does temperature affect the "liquid-polymer equilibrium contact distance"?

Temperature can have a significant effect on the "liquid-polymer equilibrium contact distance." As temperature increases, the contact distance decreases, meaning that the liquid can more easily penetrate or escape from the polymer surface. This can result in changes in the behavior of the liquid on the surface.

5. Can the "liquid-polymer equilibrium contact distance" be altered?

Yes, the "liquid-polymer equilibrium contact distance" can be altered through various methods such as changing the surface properties of the polymer, altering the temperature, or using different liquids with varying surface tensions. Understanding and controlling this distance is important in various industries such as coatings, adhesives, and biomedical applications.
