...These two factors are contradictory, and the final hydrophobic recovery depends on the relative comparison of the two factors [28]....
[...]
...These particles and ultraviolet will break the chemical bonds and cause the degradation of macromolecular chains into low weight molecules (LWM) [24, 28]....
[...]
...With the enhancement of corona discharge by increasing of voltage, there are more LWMs and crosslinking of molecular structure....
[...]
...Generally, with the intensity increasing of corona treatment, the crosslinking process prevents the LWM from transferring to the surface layer and thus the hydrophobic recovery is impeded....
[...]
...Under high electric field, charged particle will be accelerated and bombard the material surface with high energy, cutting off the macromolecular chains, producing active groups and inducing degradation [28, 29]....
