Abstract

Semidilute solution of Cellulose in 8 wt % LiCl/N,N-dimethylacetamide was investigated using static light scattering (SLS) and rheological measurements. The reduced osmotic modulus estimated by SLS measurement for native cellulose solutions is proportional to c^1.16 in semidilute region. From the exponent of 1.16, the scaling theory gives the relationship between R _g, and M_w, of native cellulose as R_g ∝ M^0.62, which leads to the Mark-Houwink-Sakurada exponent of 0.86. This is very close to the exponent of 0.85 estimated form the rheological measurements for plant cellulose solutions.
