" ionic hygroscopic positively charged polyelectrolyte and polymethacrylic acid...  ambient conditions... water evaporation as separated nanophases embedded in the soft PDMAEA-Q/PMAA matrix... Such a hierarchical nanoconfinement imparts hydrogel microfibers with very high mechanical properties. For example, the hydrogel fiber is rather robust with a high Young′s modulus of 428 MPa and elongation of 219%... actuating fibers of prosthetic limbs or wearable devices"
