- the air phase 19 in the container 12 is depressurized, the boiling point of the liquid 11 decreases, water vapor is more likely to be generated, the vapor pressure inside the water vapor bubbles increases, and the number of water vapor molecules leading to plasma generation increases. Therefore, plasma discharge becomes easy.

- an article having a hydrophilic surface is suitable. Specifically, a hydrophilic organic polymer material, glass, ceramics, silicon wafer, metal (for example, aluminum, copper, tandastene, etc.) , Graphite, carbon fiber and the like.
- the “hydrophilic surface” is defined as having the value of the contact angle ⁇ defined in FIG.

- the contact angle of water with the hydrophilic surface is preferably as low as possible, specifically 80 ° or less, more preferably in the range of 70 ° to 0 °.
- the definition of the contact angle ⁇ in the present invention is the same as the contact angle, which is a general indicator of the wetting of the material with respect to water.
- the contact angle which is a general indicator of the wetting of the material with respect to water.
- I quote the items described in “Molding Surface”, published by Modern Editor, 1984, p. 133.
- the following equation (1) is established in FIG.
- the contact angle ⁇ of the water droplet is used to quantify the elasticity is based on the equation (2).
- the liquid is water, and ⁇ is 72.8 dynZcm (“Science Chronology”) at 20 ° C.
- a smooth material surface is prepared, this surface is kept horizontal, water drops are dropped on the surface, ( ⁇ Z2) is measured with a contact angle meter, and the contact angle in FIG. Find ⁇ .
- the material surface is porous or has irregularities, prepare a smooth surface with the same material, and calculate ⁇ on the smooth surface.
- a smooth surface can be obtained by melting the same material.
- a smooth sheet that also has a precursor material for example, polyacrylonitrile or polyimide
- the water used in the measurement of contact angle is clean water such as ultrapure water and ion exchange water.
- Biocompatible material Hydrogel (Ref. B 5)
- Biocompatible materials Cellulose and poly (bull alcohol) (reference b 6)
- the solid surface tension of ⁇ -Fe is 1670-2127dyn /
- the solid surface tension of cm, copper is about 1500 dynZcm, which is described to be much larger than the surface tension of polymers. It is.
- the surface tension of water is 72.8 dynZcm. That is, the surface of a clean metal is a surface that is very wettable with water.
- the surface treatment of the present invention can be applied to a clean metal material having a high surface energy.
- any material such as an organic polymer material, glass, ceramics, metal, graphitic carbon material, carbon fiber and the like can be applied as long as ⁇ 90 degrees is satisfied.
- the temperature is as high as about 5000 K. If the high temperature plasma gas mentioned above is brought into contact, it will be instantly destroyed without a trace.
- the present inventors can clean by decomposing or removing only the organic matter on the article surface that hardly damages the article surface. The present inventors have found that the surface cleaned can be etched without destroying the cleaned article.
- FIG. 3 The idea of the present invention to avoid thermal decomposition is schematically shown in FIG. As shown in Fig. 3, when the material is brought into contact with water vapor bubbles in water, if the contact angle ⁇ of the material with respect to water is 90 degrees or less, the contribution of thermal decomposition etching is reduced to 90 degrees. It has been found that the contribution of pyrolytic etching increases beyond this range. The reason for this phenomenon is as follows.
- a material having a ⁇ force of 3 ⁇ 40 degrees or less has its surface covered with a water layer in a liquid containing water, and even when water vapor bubble plasma approaches, the water on the surface of the material evaporates, It takes away the latent heat of evaporation from the surroundings of the material, and water is constantly supplied to the hydrophilic surface, so that a permanent cooling effect acts on the material surface and the temperature rise of the article is suppressed.
- the surface temperature of the article does not exceed the heat resistance temperature of the material, the contribution of etching by thermal decomposition is reduced, and damage to the material is suppressed. This effect is also effective in preventing excessive graphite defects locally due to the heat of plasma in the surface treatment of carbon fibers.
- the dirt on the surface of the material is decomposed under the action of thermal decomposition of the water vapor bubble plasma by heat and decomposition of acid / sodium by OH radicals.
