PROBLEM TO BE SOLVED: To provide a functional gel holding minute bubbles therein.SOLUTION: A prescribed high-pressure gas is sent into a bottom portion of an airtight container 1 from a compressed gas source 2 with a valve of a pipeline 3 opened, with a valve of another pipeline 5 closed and with a valve of an exhaust pipe 6 opened, so that the gas in a gas phase region in the upper part of the airtight container 1 is discharged and the gas phase region is filled with the prescribed gas. Next, the valve of the exhaust pipe 6 is closed, so that the pressure in the gas phase region is made higher. When the pressure in the gas phase region becomes higher, the solubility of the gas also becomes higher and a large amount of the gas is dissolved in water. After this, the valve of the pipeline 5 is opened and the high-pressure water in which the prescribed gas is dissolved up to the saturation solubility under high pressure is supplied to the water packed in another container 4 in advance. As a result, the pressure of the supplied high-pressure water is released in the water in the container 4 and the dissolved gas becomes minute bubbles. Then, a gelling agent is added into the container 4 so that the water (the low-viscosity solution) including minute bubbles is made gelatification.COPYRIGHT: (C)2012,JPO&INPIT【課題】 内部に微細気泡を保持した機能性ゲルを提供する。【解決手段】 配管3のバルブを開、配管5のバルブを閉、排気管6のバルブを開とした状態で、圧気源2から密閉容器1の底部に所定の高圧ガスを送り込み、密閉容器1の上部の気相領域内のガスを追い出し、気相領域内が所定のガスで充填し、次いで、排気管6のバルブを閉とし、気相領域内を高圧とする。気相領域内が高圧となるとガスの溶解度も上昇し多量のガスが水中に溶解する。この後、配管5のバルブを開とし、容器4内に予め満たしておいた水中に前記所定のガスが高圧での飽和濃度まで溶解している高圧水を供給する。すると、供給された高圧水は容器4内の水中で圧力解放され溶存ガスが微細な気泡として発生する。この後、容器4内にゲル化剤を添加し、微細気泡が含まれる水(低粘性の溶液)をゲル化する。【選択図】 図1
