ABSTRACT:
A three dimensional porous matrix, such as a reticulated open-cell foam, having within its matrix structure a mechanically-fractured hydrogel containing a network of fracture channels. The mechanically-fractured hydrogel may be a gel that has been partially dewatered by compression of the gel in situ.
The porosity of the gel-in-matrix makes it useful for chromatographic applications and for immobilization of biologically-active components, where efficient, intimate contact of the hydrogel with a liquid medium is important.
