Patent ID: 8568769

Claim:
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.
