a) Stress–strain behavior of Sylgard 184/Ecoflex 00–30 blend with different mixing ratio. Shown are the arithmetic means of the stress–strain data of four individual samples (blue symbols) of each elastomer blend (20 wt% steps), the ±1σ confidence intervals (blue shaded areas) and the respective Gent fits (blue dashed lines). b) Young's moduli of the blends: experimental values and theoretical modelling using the Halpin‐Tsai composite model, together with experimental and theoretical values for the extreme configurations of purely serial and purely parallel alignment. c) The increasing stiffness of the Sylgard 184/Ecoflex 00–30 blends visualized by gravitational bending. d,e) Combination samples for serial and parallel alignment of the elastomers.
