          Functional thin coatings for wood and fibre-based materials


                                   GOALS
                                   •Scratch resistance, wear resistance: to
                                   increase the utility value and durability of wood and

                                Smart Filter - adaptable pore size

                                                     • Fiber filters coated by PNIPA polymer
                                                     • At temperatures <T LCST. 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.
