Fig. 10From: Novel ultra-stretchable and self-healing crosslinked poly (ethylene oxide)-cationic guar gum hydrogelSelf-healing behavior A, semiquantitative flexibility B, and rheological comparison of CGG-PolyOX before and after self-healing C and D. The sample taken for the study was 20 g, and the time indicated in the lower right represents the time elapsed from the extension of the HG to its rupture due to gravity. CGG-PolyOX has a transparent appearance. However, to evidence self-healing, which occurred in an average of 12.5 ± 2.5 min, the HG was stained with D&C Red No. 33, CI 17200Back to article page
