METHOD AND APPARATUS FOR MODIFYING FLUORORESIN

To provide an improved method and apparatus for modifying a fluororesin.SOLUTION: A method for modifying a fluororesin includes: a first step of irradiating a first fluid containing an organic compound containing at least any one of oxygen atoms and nitrogen atoms with ultraviolet light indicating intensity in a wavelength region of at least 205 nm or less, and bringing the first fluid irradiated with the ultraviolet light into contact with a fluororesin; and a second step of irradiating a second fluid containing gas or misty water with the ultraviolet light, and bringing the second fluid irradiated with the ultraviolet light into contact with the fluororesin. A modifying apparatus includes at least one fluid supply port for supplying a first fluid containing an organic compound containing at least one of oxygen atoms and nitrogen atoms, and a second fluid containing gas or misty water into a chamber, and a light source for irradiating the first fluid and second fluid in the chamber with ultraviolet light indicating intensity in a wavelength region of a wavelength of 205 nm or less.SELECTED DRAWING: Figure 1 【課題】改善したフッ素樹脂の改質方法及び改質装置を提供する。【解決手段】フッ素樹脂の改質方法は、酸素原子と窒素原子の少なくとも一方を内包する有機化合物を含む第一流体に少なくとも２０５ｎｍ以下の波長域に強度を示す紫外光を照射し、前記紫外光が照射された前記第一流体をフッ素樹脂に接触させる第一工程と、ガス又は霧状の水を含む第二流体に前記紫外光を照射し、前記紫外光が照射された第二流体をフッ素樹脂に接触させる第二工程と、を備える。改質装置は、酸素原子と窒素原子の少なくとも一方を内包する有機化合物を含む第一流体、及び、ガス又は霧状の水を含む第二流体を、チャンバ内に供給するための、少なくとも一つの流体供給口と、波長２０５ｎｍ以下の波長域に強度を示す紫外光を、前記チャンバ内の前記第一流体と前記第二流体に向けて照射する光源と、を備える。【選択図】図１
