摘要：
Rheological properties of blend spinning solution of sodium alginate and TiO2 nanoparticles (SA/nano-TiO2) were investigated. The rheological parameters, structural viscosity iaclex (Delta eta) and flow activation energy (E-eta) of spinning solutions were calculated. The results reported that the blend spinning solutions were non-newtonian fluids. The apparent viscosity, consistency index (k) and En increased with increasing nano-TiO2 content in SA spinning solution, but the degradation degree of apparent viscosity decreased, flow behavior index (n) only slightly cecreased and the Delta eta had no significantly change. The apparent viscosity (eta(a)) of spinning solutions could be regulated by changing temperature under 50 degrees C. Blend spinning solution had good stability and practical applicability.
