Rheological Properties of Suspensions of Nanocrystalline Cellulose in Polymer Solutions

摘要

1. The addition of NCC to HEC solution leads to an increase of the viscosity. 2. There exists a critical concentration, above which an apparent yield stress is observed. 3. The critical concentration is dependent on the molecular weight of HEC. 4. The viscoelastic results indicate that a 3-D dimensional network is formed between polymer molecules and NCC particles above the critical concentration.
