(a) Flow curves of 2.7 wt% sodium alginate cross-linked with 12.5 mM (cyan filled circles), or 25 mM (blue open circles) calcium chloride in water in the absence of HNTs, and with 25 mM calcium chloride in the presence of 5.4 vol% HNTs (red filled squares). (b) Viscosity recovery after periodic variation of shear rate (50 s−1 for 60 s, 0.1 s−1 for 60 s, etc.) for 2.7 wt% sodium alginate cross-linked with 12.5 mM (red symbols) or 25 mM (blue symbols) calcium chloride in water in the absence of HNTs (open symbols) and the presence of 5.4 vol% HNTs (filled symbols).
