“…With increasing temperature, the n values of the solutions gradually increased, indicating that the increase of temperature was conducive to increasing the fluidities of the solutions and improving their performance. In addition, as shown in Table 3, when the CS weight content was 9.09 wt%, the n values of the BP/CS blend solution were higher than those of the pure BP solution at the same temperatures, because an appropriate amount of CS can reduce the apparent viscosity of the BP/CS blend solution and increase its fluidity, which is similar to the research results of Li et al (2016). With increasing CS weight content (from 9.09 wt% to 14.24 wt%) at a given temperature, the n values of the blend solutions gradually decreased, and the flow performance decreased.…”
