Abstract

A hybrid porous structured material may include a porous region and a non-porous region. The porous region may include an imaginary stacked structure, wherein a plurality of imaginary spherical bodies/cavities are stacked so as to contact each other in three-dimensional directions. The non-porous region fills the gaps between the imaginary spherical bodies. A spherical colloid particle is present in each of the plurality of imaginary spherical bodies in the porous region. A separation membrane may include the hybrid porous structured material. A water treatment device may include the membrane.

First claim

What is claimed is:

1. A hybrid porous structured material, comprising:
a base framework defining a plurality of spherical cavities therein, the plurality of spherical cavities being adjacent to and in communication with each other via nanopores, the base framework including at least one of a thermoplastic resin and a curable resin; and
a spherical core particle in each of the plurality of spherical cavities, the spherical core particle in each of the plurality of spherical cavities having a diameter smaller than a diameter of the spherical cavities and larger than a diameter of the nanopores, the spherical core particle in each of the plurality of spherical cavities including at least one of a thermoplastic resin and a curable resin, the spherical core particle occupying at least 60% of a volume of a respective spherical cavity of the plurality of spherical cavities.

2. The hybrid porous structured material of claim 1 , wherein the plurality of spherical cavities are disposed in a closest packing arrangement.

3. The hybrid porous structured material of claim 1 , wherein the nanopores coincide with tangential portions of adjacent spherical cavities.

4. The hybrid porous structured material of claim 3 , wherein the nanopores have an average diameter of about 1 nm to about 500 nm.

5. The hybrid porous structured material of claim 1 , wherein the plurality of spherical cavities have an average diameter of about 10 nm to about 100 μm.

6. The hybrid porous structured material of claim 1 , wherein the hybrid porous structured material has a porosity of about 0.1 to about 95 volume %.

7. The hybrid porous structured material of claim 1 , wherein the hybrid porous structured material has opposing surfaces bounded by two planes, a distance between the opposing surfaces corresponding to a thickness of the hybrid porous structured material, each of the opposing surfaces including a cross-section of the base framework and the plurality of spherical cavities.

8. The hybrid porous structured material of claim 7 , wherein the cross-section of the base framework in each of the opposing surfaces occupies about 1 to about 95% of a total area of each of the opposing surfaces.

9. The hybrid porous structured material of claim 7 , wherein side wall surfaces of the base framework are non-porous, the side wall surfaces being between the opposing surfaces.

10. The hybrid porous structured material of claim 7 , wherein the thickness is about 10 nm to about 1000 μm.

11. A separation membrane comprising the hybrid porous structured material according to claim 1 .

12. A composite membrane comprising:
the separation membrane of claim 11 ; and
a support layer.

13. A water treatment device comprising the separation membrane according to claim 11 .
