Figure 2: Gelation behaviour of PAM/CNS NC gels.
From: Super stretchable hydrogel achieved by non-aggregated spherulites with diameters <5 nm

The polymer and tricalcium silicate concentrations were fixed at 20 wt% and 500 p.p.m., respectively. (a) After being maintained at 0 °C and 1 atm for 10 days, gelation did not start at 1 atm. (b) After being maintained at 0 °C and 1 atm for 1 day, gelation started after 3 h at 0.01 atm. (c) After being maintained at 0 °C and 1 atm for 3 days, gelation started after 3 h at 0.01 atm. (d) After being maintained at 0 °C and 1 atm for 5 days, gelation started after 3 h at 0.01 atm. PAM/CNS NC gels represent polyacrylamide/calcium hydroxide nano-spherulites nanocomposite hydrogels.
