The volume of polymer is expanded state ( the polymer binds water molecules). Fibers are "thick" and pores are "small". The system is highly hydrophilic. • At temperature >T LCST , the polymer rejects water molecules out and the volume of the polymer decreases dramatically. Now the fibers are "thin" and pores are "large". The system is hydrophobic. H 2O PNIPA Now we have a filter with adjustable pore size! The washing can take place easily.
