Fig. 5. (a) Stress–strain curve of the dry PAN–PBD. (b) Young's modulus and elongation at break evaluated from (a), plotted with the cross-link density. (c and d) Frequency dependence of the storage and loss modulus (G′ and G′′), and the phase angle (δ) of PAN–PBD swollen in (c) DME + LiClO4, and in (d) DMC + EC (1 : 1) + LiClO4, evaluated under a constant strain of 0.1%.
