The main constituent of the membrane is cellulose fiber — the polysaccharide component of plant cell walls. Researchers mixed the cellulose fibers in solution with ferromagnetic salts at 90 degree Celsius, then left the mixture to bond over the course of two months. The remaining water was drained at the end of this period to reveal a hydrogel (a hydrophilic collection of polymers) composed of magnetic cellulose fibers.
