A method of making a composite porous material, said method comprising:
- directly contacting a solution comprising a solvent, in which a second material is dissolved, with a porous first material;
- wherein said first material is soluble in the solvent, such that said first and second materials are fused in the resulting composite porous material.
A method of coating the interior surface of a tubular element with a material, said method comprising:
- passing an applicator longitudinally through a horizontally positioned tubular element to apply a solution of the material to the interior surface of the tubular element.
A method of coating a tubular element with a material using an applicator with a hollow interior and at least one passage extending from the hollow interior to the exterior of the applicator, said method comprising:
- inserting the applicator into the bore of the tubular element;
- applying material in solution to the hollow interior of the applicator;
- allowing the material solution to pass through the at least one passage in the applicator to the exterior of the applicator;
- and
- causing relative movement of the applicator and the tubular element to apply material solution longitudinally along the interior surface of the tubular element.
