The results show that the zero shear viscosity η 0 of the solution decreases with the increase of acetic acid content and temperature, the decrease of chitosan content and the prolonging of the storage time, that flow activation energy (Δ E η) and structural viscosity index (Δη) increase with the increase of chitosan content and the decrease of acetic acid content,that the addition .
流动活化能ΔＥη和结构粘度指数Δη随壳聚糖含量的增加、乙酸含量的减少而增大。
Viscous activation energy, non-Newtonian index, structural viscosity index and relaxation time of the solution was determined.
本文研究了自制的聚间苯二甲酰间苯二胺(PMIA)纺丝溶液的浓度、温度及聚合物的相对分子质量对纺丝溶液的流动曲线,粘流活化能、非牛顿指数和结构粘度指数及松弛时间的影响。
