Laser Catalyst

Idaho National Laboratory

Contact INL About This Technology

Technology Marketing Summary

INL’s Laser Catalyst is a method for removing contaminant matter from a porous material. A polymer material is applied to a contaminated surface and then irradiated to cause redistribution of the contaminant matter. The final step is removal of a portion of the polymer material from the surface.

Description

The radiation device is configured to emit electromagnetic radiation toward a contaminated and polymer surface of a structure, and at least one spray device configured to apply a capture material onto the surface of the structure is needed.

Benefits

-      An alternative to removing contaminates

Applications and Industries

Contaminant matter, porous material, electromagnetic radiation, cleaning porous material

Polyphosphazine-based polymer materials
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, .beta.-diketones, phosphine sulfides, phosphates, phosphites, phosphonates, phosphinates, phosphine oxides, monothio phosphinic acids, and dithio phosphinic acids.
