a The precursor (ai, aiii, av) consists of n-butyl acrylate (nBA) as monomers and small-molecules (ai) or oligomers with two vinyl groups (–CH=CH2) (aiii and av) as crosslinkers. When exposed to ultraviolet light (UV-light), the precursoris cured to a flexible network (aii, named BA-S; aiv, named BA-M or BA-L; avi, named BAC2). Distribution of molecular weight for those oligomers have been tested by gel permeation chromatography (GPC) and shown in Supplementary Table 1. b Comparison of BAC2 before (left) and after (right) uniaxial stretched. c The stress–strain curves of commercial VHBTM4910 and BA-S, BA-M, BA-L, BAC2 at a stretch rate of 200 mm min−1. d Comparison of ultimate strength to modulus among VHBTM 4910, BA-S, BA-M, BA-L, BAC2, dielectric gel37, multiblock copolymers33, azo-grafted silicone28, nitroaniline modified silicone18, polyurethane19, alkyl thiols grafted silicone16 and commercial Elastosil@Film16. e, Toughness plotted against Young’s modulus for VHBTM 4910, BA-S, BA-M, BA-L, BAC2, dielectric gel37, silicones with ionic liquids17, acrylic copolymer25, nitroaniline modified silicone18, nitrile modified silicone39, alkyl thiols grafted silicone16, 3D printable silicone40, and commercial Elastosil@Film16 (Supplementary Discussion).
