a Lap shear curve of SST-2-10 bonded on stainless steel substrates. Lap shear stress (b) and work of debonding c of solution-sheared films bonded on stainless steel substrates. d Lap shear strength of SST-2-10 bonded on diverse substrates. e The demonstration of SST-2-10 maintaining adhesion on substrates after 30 days without failure. f Lap shear strength retention of SST-2-10 on aluminum substrates after 20 adhesion cycles. g Comparative lap shear strength of SST-2-10 and commercial hot-melt adhesives on stainless steel. h Lap shear strength comparison of SST-2-10 and commercial structural adhesives (Elmer’s Glue All, Loctite Super Glue, and Loctite Quick-Set) on glass, aluminum, stainless steel, and PTFE. i Performance benchmarking of SST-2-10 against reported polymer gels, elastomers, and resin-based adhesives in terms of lap shear strength and debonding energy. All adhesion tests were conducted in the direction parallel to nanofibril alignment. Error bars represent standard deviation (n ≥ 3).
