Abstract
The present invention discloses a method for preparing a hydrophilic porous polymeric material comprising the step of mixing a hydrophilic polymeric material with a hydrophobic material; solvent sintering the surface of the hydrophilic polymeric material with water or an aqueous solution; and removing the hydrophobic material contained within the hydrophilic polymeric material with a massive organic solvent. Thus, the hydrophilic porous polymeric material with high porosity and stable structure is rapidly mass produced.
