Fig. 4. (a) Stress–strain curves (strain rate = 10 mm min⁻¹, 25 °C), (b) dynamic mechanical analysis (DMA; temperature ramp rate = 3 °C min⁻¹, frequency = 1 Hz, tensile geometry) and (c) shear rheology (temperature ramp rate = 3 °C min⁻¹, frequency = 2 Hz, parallel plate geometry) curves for 2N100 (red), 2N50B50 (dashed orange), 2N50H50 (dashed blue), 2N50M50 (dashed green), and 2H100 (blue).
