Filtration media including porous polymeric material and degradable shape memory material

A fluid control method comprising:

• deploying a fluid control device in a borehole, the fluid control device including a support structure and a filtration medium, the filtration medium being in a compacted shape during deployment, 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, wherein the shape memory polymer is configured to retain the compacted shape of the filtration medium prior to expansion of the shape memory polymer;
• expanding the shape memory polymer in the plurality of fluid passages to cause the filtration medium to expand and conform to a surface of the borehole;
• removing the shape memory polymer from the porous structure;
• and
• flowing a fluid through the porous structure and filtering undesirable material from the fluid.
