  • Method for preparing hydrophilic porous polymeric materials
    Patent number: 6635684
    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.
    Type: Grant
    Filed: October 19, 2001
    Date of Patent: October 21, 2003
    Assignee: Industrial Technology Research Institute
    Inventors: Huey-Min Lai, Chun-Hui Chang, Chun-Jen Liao, Chin-Fu Chen, Kuei-Hung Wu, Yuan-Chia Chang, Yu-Yen Jan, Tsung-Yi Mou
