To provide a porous organic-inorganic composite material widely used as biomaterial, especially supplement material for teeth and bones, a filler for columns and environmental material for absorbing contaminants, a method for producing a fibrous organic material and a method for producing the porous organic-inorganic composite material by using the fibrous organic material.
The porous organic-inorganic composite material comprises fibrous calcium phosphate and the fibrous organic material and at least a part of the fibrous organic material and the fibrous calcium phosphate are interlaced. The method for producing the fibrous organic material comprises a process for preparing a mixture solution by mixing a solvent solution prepared by dissolving the organic material into the solvent with a water soluble polymer and a water soluble polymer coagulant, and a process for removing the solvent component in the mixture solution with agitating the mixture solution. The method for producing the porous organic-inorganic composite material is to mix the fibrous organic material with the fibrous calcium phosphate and weld the mixture.
