Claim:
1. A method for manufacturing polysilsesquioxane (PSSQ), the method comprising: (i) preparing a silane compound; (ii) preparing a carbon dioxide solvent; (iii) injecting the silane compound into a reactor; (iv) increasing a pressure and temperature within the reactor, and changing a state of the carbon dioxide solvent into a liquid state or a supercritical state by injecting the carbon dioxide solvent into the reactor, wherein the pressure and temperature are increased from 1,000 to 5,000 psi and from 30 to 80° C., respectively; (v) supplying water and a catalyst to the reactor; (vi) inducing hydrolysis and a condensation reaction by increasing the temperature within the reactor; (vii) precipitating a polysilsesquioxane (PSSQ) product substituted with a functional group by controlling the temperature and pressure within the reactor; and (viii) separating the silane compound of an unreacted material within the reactor from the polysilsesquioxane (PSSQ) of a product.
