Cleans using atmospheric pressure plasma

See the change in the true contact angle.
Before the white polymer (polypropylene) is treated, the water spreads a little, but after plasma processing the surface becomes extremely hydrophilic.

Surface processing using atmospheric plasma

Organic compounds are broken down by exposure to oxygen radical and a layer of molecules including oxygen acts to increase the hydrophilicity of the surface.

Surface analysis (XPS survey and C1s composition)

The binding ratio for the surface of polyether ether ketone (PEEK) is reduced by plasma processing, and the binding ratio of hydrophilic functional groups (carbonyl group and carboxyl group) that include oxides such as [C-O], [C=O], and [COO] is increased.
