DISCRETE HYDROPHILIC-HYDROPHOBIC POROUS MATERIALS AND METHODS FOR MAKING THE SAME

摘要

This invention relates to porous polymeric materials having discrete regions that exhibit distinct surface properties. The invention also relates to methods of making such porous polymeric materials and their applications. Th e geography of the discrete regions can be determined in a selective and controlled manner. Porous materials having discrete regions of distinct hydrophilicity, hydrophobicity, oleophobicity, biological molecules binding capability, wetting and wicking property, presence or density of functional groups, chemical reactivity, electric charges, porosity and pore sizes can b e manufactured using this invention.
