Abstract
An embodiment of the present invention relates to a composite material including a hydrophobic porous organic polymer bead. An embodiment further relates to a method of obtaining the composite material as well as the use thereof.
Claims18
A composite material, comprising:
- a hydrophobic porous organic polymer bead including a hydrophobic non-porous polymer phase and pores,
- wherein said hydrophobic non-porous polymer phase internally comprises a hydrophilic polymer,
- wherein the composite material includes a substantially hydrophobic outer surface and pores having surfaces being less hydrophobic than said outer surface;
- and
- wherein the pores are substantially free from the hydrophilic polymer.
2 more elements
A method for preparing a composite material, said method comprising:
- providing at least one hydrophobic porous organic polymer bead comprising a hydrophobic non-porous polymer phase and pores;
- and a mixture of at least one hydrophilic monomer, selected from monomers having at least one polymerizable group;
- optionally an initiator;
- and optionally a solvent;
- swelling said bead in said mixture, forming a swollen hydrophobic porous organic polymer bead comprising said mixture internally in the hydrophobic non-porous polymer phase;
- polymerizing said at least one hydrophilic monomer;
- and
- obtaining said composite material, wherein the pores are substantially free from the hydrophilic polymer;
- wherein all of said mixture is absorbed by said hydrophobic porous organic polymer bead;
- or any excess removed before polymerization.
