摘要:
A process for forming polysaccharide structures such as beads, gel films and porous coatings on porous substrates by forming a room temperature gel-inhibited solution of a polysaccharide, one or more gel-inhibiting agent(s) and a solvent such as water, heating the mixture until all the components are dissolved, cooling the mixture as a solution to about room temperature, forming a three dimensional structure with the solution and adding the structure to a gelling agent to form a polysaccharide gel. Optionally, the solution can be added to a porous structure such as a non-woven fabric or a porous membrane and the solution is allowed to dry before being subjected to the gelling agent. Porous structures having a polysaccharide coating and being capable of convective flow through the pores of the structure and diffusive flow through the coating can be formed.
