Abstract
This invention relates to a composite material that comprises a support member that has a plurality of pores extending through the support member and, located in the pores of the support member, and filling the pores of the support member, a macroporous cross-linked gel. The invention also relates to a process for preparing the composite material described above, and to its use. The composite material is suitable, for example, for separation of substances, for example by filtration or adsorption, including chromatography, for use as a support in synthesis or for use as a support for cell growth.
Claims23
A composite material comprising:
- (a) a support member comprising a plurality of pores extending through the support member;
- and
- (b) a non-self supporting macroporous cross-linked gel comprising macropores having an average size of 10 nm to 3000 nm, said macroporous gel being located in the pores of the support member;
- wherein said macroporous cross-linked gel is present in the pores of the support member in an amount sufficient such that, in use, liquid passing through the composite material passes through said macropores of said macroporous cross-linked gel;
- and
- wherein said macropores of said macroporous cross-linked gel are smaller than said pores of said support member.
