Extended Data Fig. 3: Glassy gels have multiple functions.

a, The ionic bonds give strong adhesion to surfaces despite being stiff and glassy (Middle: metal ball diameter from left to right: 0.25 inch, 0.5 inch and 1 inch). b, Heating-induced shape memory (width = 4 mm, length = 4.7 cm). The scale bar is 10 mm. c, Self-healing behavior. The gels merge together after healing at 80 °C for 60 s and are able to support a 500 g hanging weight. The diameter of the gel and the hole is 12 and 3 mm, respectively. In a-c, PAA-PP-6.0 M glass gel with a thickness of 1 mm is used.
