PROBLEM TO BE SOLVED: To provide a method for producing a siloxane-based porous body, which can easily control the pore diameter. SOLUTION: A siloxane-based porous body comprising a step of 1) obtaining a gel containing siloxane and having stimuli responsiveness, and 2) a step of removing at least a part of a solvent of the obtained gel to obtain a siloxane xerogel. In the production method, the pore size of the porous body is controlled by adjusting the siloxane concentration of the gel. Furthermore, when the solvent removal of the gel is performed by lyophilization, the pore diameter is controlled by adjusting the freezing conditions. [Selection] Figure 1-c |
