Figure 1: PAM enhanced by non-aggregated CNS.
From: Super stretchable hydrogel achieved by non-aggregated spherulites with diameters <5 nm
(a) TEM image of CNS released from a tricalcium silicate (Ca3SiO5) particle. The scale bars of the whole image and inset are 100 and 5 nm, respectively. (b) Electron diffraction patterns of CNS released from a hydrolysed Ca3SiO5 particle. Scale bar, 5 nm−1. (c) TEM image of CNS dispersed in C200 (PAM/CNS NC gel with 200 p.p.m. CNS concentration). Scale bar, 30 nm. (d) Optical photos of a cylindrical C200 specimen with a diameter of 2.7 cm and thickness of 1.2 cm against a background of characters. Scale bar, 1 cm. The transparency of C200 is almost the same as the original PAM hydrogel. PAM represents polyacrylamide; CNS represents calcium hydroxide nano-spherulites.
