<p>PROBLEM TO BE SOLVED: To provide a polysiloxane porous body which has flexibility while having a skeleton composed of polysiloxane, is hardly lost in a liquid repellent property even with the contact of a substance, and can achieve a super liquid repellent property.SOLUTION: A production method of a polysiloxane porous body comprises the steps of: obtaining gel having a co-continuous structure of a skeleton phase, rich in polysiloxane being a polymer of silicon compounds and having a reactive group, and a solution phase, by performing hydrolysis and polymerization of silicon compounds and performing phase separation of a solution system by a sol-gel process in the solution system comprising a bifunctional silicon compound and a polyfunctional silicon compound, at least one of the silicon compounds having a reactive group; drying the gel and obtaining a polysiloxane porous body having a co-continuous structure of the skeleton phase as a skelton and the solution phase as a macropore; and performing chemical reaction of the reactive group in the polysiloxane with a compound having a liquid repellent group, thereby bonding the polysiloxane to the liquid repellent group.</p> |
