Abstract: A method for bonding a porous flexible membrane to a rigid material is disclosed. In some embodiments, the method includes applying, at a bonding site of the porous membrane, a pre-treatment solvent solution, drying the bonding site of the porous membrane, applying, at a bonding site of the rigid structure, a first solvent that is capable of dissolving a surface of the rigid material, applying, at the bonding site of the porous membrane, a second solvent that is capable of dissolving the polymeric residue material dissolved in the pre-treatment solvent solution, and pressing the porous membrane to the rigid material at their respective bonding sites. In some embodiments, the pre-treatment solvent solution may include a solvent carrying dissolved polymeric residue material configured to fill the pores of the porous membrane at the bonding site of the porous membrane.
