NOVEL POROUS POLYMER MONOLITHS ADAPTED FOR SAMPLE PREPARATION
A porous polymer monolith comprises a polymer body having macroporous through-pores that facilitate fluid flow through the body and an array of mesopores adapted to bind from the fluid flow molecules of a predetermined range of sizes, wherein the surface area of the monolith is predominantly provided by the mesopores. Also disclosed is a method of making a porous polymer monolith. The method includes forming a polymer body by phase separation out of a solution containing at least a monomer, a crosslinker and a primary porogen, whereby the body contains multiple macroporous through-pores, wherein the solution further contains a secondary porogen comprising oligomers inert with respect to the monomer and cross-linker but chemically compatible with the monomer so as to form mesostructures within the polymer body during said phase separation, and washing the mesostructures from the body to provide an array of mesopores such that the surface area of the monolith is predominantly provided by the mesopores.
