Fig. 3: Electrical transport property of the AgNS-AgFL-SR nanocomposite.

a The electrical conductivity of the AgNS-AgFL-SR nanocomposite as a function of THF peroxide amount in the initial mixture. The error bars represent the standard deviation of the data. The Ag filler fraction was fixed at 44 vol%. Optical images of the nanocomposites are provided in the inset. b, c The electrical conductivity and density of the AgNS-AgFL-SR nanocomposites are compared with those of control specimens as a function of the total Ag filler fraction. The density was measured by the Archimedes method. The amount of THF and THF peroxide was fixed at 15 mL. The electrical conductivity of the graphite-incorporated healable viscoelastic nanocomposite is also compared¹⁷. The error bars represent the standard deviation of the data. d The normalized resistance of the AgNS-AgFL-SR (Ag = 44 vol%, THF peroxide = 15 mL) nanocomposite as a function of compressive strain. The error bars represent the standard deviation of the data. The resistance was measured in steady state after relaxation at each strain. The inset image shows the measurement setup. e, f The mechanical stress and electrical resistance relaxation of the AgNS-AgFL-SR (Ag = 44 vol%, THF peroxide = 15 mL) nanocomposite after compressive step strain (strain rate = 1% s⁻¹).
