Abstract
Provided are an improved method and device for modifying a fluororesin. The method for modifying a fluororesin includes: a first step in which a first fluid containing an organic compound including at least one of an oxygen atom and a nitrogen atom is irradiated with ultraviolet light exhibiting intensity in at least a wavelength region of 205 nm or less, and the first fluid that has been irradiated with the ultraviolet light is brought into contact with a fluororesin; and a second step in which a second fluid containing water in the form of gas or mist is irradiated with the ultraviolet light, and the second fluid that has been irradiated with the ultraviolet light is brought into contact with the fluororesin.
Claims12
A method for modifying a fluororesin, the method comprising:
- a first step in which a first fluid containing an organic compound including at least one of an oxygen atom and a nitrogen atom is irradiated with ultraviolet light exhibiting intensity in at least a wavelength region of 205 nm or less, and the first fluid that has been irradiated with the ultraviolet light is brought into contact with a fluororesin;
- and
- a second step in which a second fluid containing water in the form of gas or mist is irradiated with the ultraviolet light, and the second fluid that has been irradiated with the ultraviolet light is brought into contact with the fluororesin.
A modification device comprising:
- at least one fluid supply port for supplying, into a chamber, a first fluid containing an organic compound including at least one of an oxygen atom and a nitrogen atom and a second fluid containing water in the form of gas or mist;
- and
- a light source that emits ultraviolet light exhibiting intensity in a wavelength region of 205 nm or less toward the first fluid and the second fluid in the chamber,
- wherein a surface layer of an object to be processed is hydrophilized by the first fluid that has been irradiated with the ultraviolet light and the second fluid that has been irradiated with the ultraviolet light.
