Methods for removing contaminant matter from a porous material
First Claim
1. A method of removing contaminant matter from a porous material, the method comprising:
- applying a polymer material to a surface of a porous material comprising contaminant matter in at least one pore thereof;
irradiating the surface of the porous material with electromagnetic radiation to cause redistribution of the contaminant matter; and
removing at least a portion of the polymer material having at least a portion of the contaminant matter bound thereto from the surface of the porous material.

Abstract
Methods of removing contaminant matter from porous materials include applying a polymer material to a contaminated surface, irradiating the contaminated surface to cause redistribution of contaminant matter, and removing at least a portion of the polymer material from the surface. Systems for decontaminating a contaminated structure comprising porous material include a radiation device configured to emit electromagnetic radiation toward a surface of a structure, and at least one spray device configured to apply a capture material onto the surface of the structure. Polymer materials that can be used in such methods and systems include polyphosphazine-based polymer materials having polyphosphazine backbone segments and side chain groups that include selected functional groups. The selected functional groups may include iminos, oximes, carboxylates, sulfonates, β-diketones, phosphine sulfides, phosphates, phosphites, phosphonates, phosphinates, phosphine oxides, monothio phosphinic acids, and dithio phosphinic acids.
