Topic: Hydrophilization through plasma activation. Plasma hydrophilization.
Optimal functionality for fishing lines, thanks to hydrophilisation achieved with plasma pre-treatment
is admittedly a relatively minor use, but it
is nonetheless a good example of the impact of surface tension when
two media meet. Fishing line that is not pretreated will always float
on the surface of the water, where it causes refraction and is
visible to fish.
This can be explained by the spreading of a drop of water on a polymer surface. The hydrophilisation achieved by Openair® plasma treatment increases surface tension on the line to > 72 mN. Wettability improves and water spreads out across the surface. As a result, the fishing line drops below the surface of the water and is almost invisible. Then it’s just a matter of time until the fish bite...
