Extended Data Fig. 9: Adhesion performance of the R1-max hydrogel on various substrates.
From: Data-driven de novo design of super-adhesive hydrogels
(a) Schematic illustration of lap shear and 180° peeling tests for adhesion assessment. (b) Force-displacement curves from lap shear tests of R1-max (10 mm diameter, ~0.4 mm thickness) adhering to glass, PET, and PC substrates. (c) Force-displacement curves from 180° peeling tests of R1-max (10 mm × 150 mm strips, ~0.4 mm thickness) adhering to glass, PET, PC, and pork bone surfaces. (d) Lap shear adhesive strength and 180° peeling interfacial toughness of R1-max on various substrates. (e) Photographic images (from different perspective angles) showing R1-max (25 mm × 150 mm strips, ~0.4 mm thickness) being peeled away from a pork bone surface. All hydrogels were equilibrated in normal saline before testing. Error bars represent the standard deviation of N = 3 measurements. Experimental details are provided in the Methods section. These results highlight the exceptional adhesion performance of R1-max on various surfaces.
