The mixture of first and second materials is then consolidated using heat to melt the first or second material, while the other one of the first or second material remains in a solid state and acts as a space holder. Thereafter, the material which acts as the space holder may be removed thereby to leave a substantially continuous porous network defined by the material which was melted. It is found that, by use of the method, a substantially continuous network of the material which is melted can be formed and that the other material can readily be removed and/or is more easily removed compared to if a mixture of first and second materials was formed prior to packing in a column or mold.

A method of preparing core-shell submicron spheres is disclosed. The method comprises steps hereafter. An emulsion containing a core monomer is heated to a temperature of 10° C. below its boiling point to the boiling point. A core forming step is performed by adding an initiator solution to the heated emulsion to form cores by polymerizing the core monomer. When the conversion of the above polymerization is 10% to 95%, a shell forming step is performed by adding a shell monomer into the emulsion, at a temperature of 50° C. below the emulsion's boiling point to the boiling point thereof, to form shells, respectively surrounding the cores, by polymerizing the shell monomer.
