Flow characteristics of liquid crystalline polymer (LCP) solutions with carbon nano fibers (CNF) dispersed have been investigated experimentally. CNF with very high aspect ratio was dispersed in HPC 50 w% aqueous solution at 0.5 w%. A standard viscosity measurement with a rheometer was conducted and repeated. The second or third measurements were started after previous measurement in high shear rate region with almost no time lag. In the first measurement, the dispersed system showed relatively simple shear thinning viscosity without region 2 which appeared in the viscosity curve of LCP only. Decreased apparent viscosities were obtained in the low shear rate region in the repeated tests. It is considered that alignment structure of CNF was maintained in the succeeding measurements.
