Extended Data Figure 1

a, Lap-joint geometry. Displacement was measured by a video extensometer that followed two markers (white dots), which were placed at a distance of 5 mm from the edge of the lap joint. The total length of the assembled ribbons was 40 mm. w denotes the width and h the thickness of gel ribbons. l is the overlap length. b, Comparison of force–displacement curves for PDMA S0.1 ribbon (black line) and for the lap joint glued by spreading 15 μl of TM-50 silica solution (blue circles). Displacement was measured by optical extensometer from two markers, initially spaced by 20 mm and centred on the joint. The PDMA S0.1/S0.1 assemblies broke outside the joint (inset). c, Lap-shear adhesion test reproducibility. Force–displacement curves of PDMA S0.1/S0.1 lap joint illustrating lap-shear test reproducibility. All gel ribbons were cut from the same plate. Bulk failure outside the joint was systematically observed.
