ABSTRACT:
A method for bonding a porous medium to the surface of a solid substrate is disclosed. The method comprises contacting a dry porous medium with a dry surface of a substrate and impregnating the porous medium with a bonding composition. The impregnated porous medium is maintained in contact with the substrate surface until the substrate surface is at least slightly dissolved in the bonding composition without dissolving the porous medium. At least a portion of the bonding composition is flushed through the impregnated porous medium towards the substrate and subsequently away from the surface of the substrate. The bonding composition is then evaporated at a controlled rate from the substrate and the porous medium.
