Fig. 4: Adhesive properties of T-ECH and T-ECA.
From: Highly conductive tissue-like hydrogel interface through template-directed assembly
a Schematic illustration of adhesion mechanism of T-ECA. T-ECA is made by activating the adhesive layer on the surface of T-ECH. b 180 degrees peeling test, and shear test conducted with pig skin. The data plotted represents the mean and standard deviation (n = 3, n means the number of the independent experiment). c 180 degrees peel test conducted two weeks after applying on the porcine skin. d 180 degrees peeling test of T-ECA hydrogels activated from T-ECH hydrogels, with various wet tissues including porcine skin, artery, kidney, heart, and liver. The data plotted represents the mean and standard deviation (n = 3, n means the number of the independent experiment). e Optical camera images of strongly attached T-ECA on various tissues.
