Figure 4. Mechanical properties of DPI-HFP/Fe₃O₄ NPs/Ecoflex 00-30 composite. (A) Photographic images of DPI-HFP/Fe₃O₄ NPs (1.00 wt.%)/Ecoflex 00-30 composite sheet (middle), which is uniaxially stretched (top left), biaxially stretched (top right), twisted (bottom left), and poked (bottom right); (B) Relative mechanical properties of neat Ecoflex 00-30 (black) and DPI-HFP/ Fe₃O₄ NPs/Ecoflex 00-30 composite (red); (C) Variation in hysteresis loss ratio of neat Ecoflex 00-30 (black) and DPI-HFP/ Fe₃O₄ NPs/Ecoflex 00-30 composite (red) with respect to strain range (100-400%). (B) Data are presented as mean ± SD of n = 3 independent measurements. NP: Nanoparticle; DPI-HFP: diphenyliodonium hexafluorophosphate; SD: standard deviation.
