First Claim
Patent Images
1. A method for preparing a porous inorganic coating on a porous support, which comprises:
- providing a porous support comprising a first end, a second end, and a plurality of inner channels having surfaces defined by porous walls and extending through the support from the first end to the second end;
modifying the inner channel surfaces of the support by applying to the inner channel surfaces a composition comprising an organic pore-filling material comprising protein particles;
applying to the modified inner channel surfaces a coating comprising inorganic particles; and
heating the coated support to remove the organic pore-filling material, leaving the porous inorganic coating on the porous support.

Abstract
Methods for preparing porous inorganic coatings on porous supports using certain pore fillers, and porous supports coated with porous inorganic coatings. The porous inorganic coatings may serve as membranes useful in, for example, liquid-liquid, liquid-particulate, gas-gas, or gas-particulate separation applications.
