1. A fluid control device comprising:
a support structure configured to be deployed to a selected location in a borehole; and
a filtration medium disposed at the support structure and configured to filter a fluid, the filtration medium configured to be compacted from an initial shape to a compacted shape prior to deployment in the borehole, the filtration medium including:
a first polymeric material configured to withstand a temperature at the selected location, the first polymeric material forming a porous structure including a plurality of fluid passages, wherein the fluid passages include pores defined by the porous structure; and
a second polymeric material including a shape memory polymer disposed within the fluid passages and filling the pores defined by the porous structure of the first polymeric material, the shape memory polymer configured to expand in the plurality of fluid passages and cause the filtration medium to expand in the borehole, wherein the shape memory polymer is configured to retain the compacted shape of the filtration medium prior to expansion of the shape memory polymer.
