Abstract
Porous materials and methods for forming them are disclosed. One method for immobilizing micro-particles and/or nano-particles onto internal pore surfaces and/or external pore surfaces of porous materials includes suspending the micro-particles and/or nano-particles in a liquid adapted to swell, soften, and/or deform either the porous materials and/or the particles, thereby forming a liquid-particle suspension. The method further includes adding the suspension to the porous materials; and removing the liquid, thereby forming the porous materials having the micro-particles and/or nano-particles immobilized on the internal pore surfaces and/or the external pore surfaces.
Claims16
A method for immobilizing at least one of micro-particles or nano-particles onto at least one of internal pore surfaces or external pore surfaces of porous materials, the method comprising:
- suspending the at least one of micro-particles or nano-particles in a non-solvent of both the porous materials and the at least one of micro-particles or nano-particles, thereby forming a non-solvent-particle suspension;
- and then adding the suspension to the porous materials;
- removing the non-solvent to form the porous materials having the at least one of micro-particles or nano-particles loosely adhered on at least one of the internal pore surfaces or the external pore surfaces;
- adding a liquid adapted to perform at least one of swelling, deforming, or slightly dissolving of at least one of the porous materials or the at least one of micro-particles or nano-particles to the porous materials having the at least one of micro-particles or nano-particles loosely adhered thereon, thereby at least one of swelling, deforming or slightly dissolving at least one of the porous materials or the at least one of micro-particles or nano-particles and strongly adhering the at least one of micro-particles or nano-particles on the at least one of the internal pore surfaces or the external pore surfaces;
- and
- removing the liquid, thereby forming the porous materials having the at least one of micro-particles or nano-particles immobilized on the at least one of the internal pore surfaces or the external pore surfaces.
A method for immobilizing at least one of micro-particles or nano-particles onto at least one of internal pore surfaces or external pore surfaces of porous materials, the method comprising:
- suspending the at least one of micro-particles or nano-particles in a liquid adapted to at least one of swell, soften, and deform but not dissolve at least one of the porous materials and the at least one of micro-particles or nano-particles, thereby forming a liquid-particle suspension;
- adding the suspension to the porous materials;
- and
- removing the liquid, thereby forming the porous materials having the at least one of the micro-particles or nano-particles immobilized on the at least one of the internal pore surfaces or the external pore surfaces.
