Abstract:

In order to investigate the effect of rheological properties of cellulose solution on the spinnability of electrospinning, the steady and dynamic rheological properties of cellulose/LiCl/N, N-dimethylacetamide(DMAc)solution were studied,and electrospinning was carried out on this basis. It was found that the cellulose/LiCl/DMAc solutions were pseudoplastic fluid. The research results showed that the apparent viscosity, consistency coefficient and structural viscosity index of the solution decrease with the increase of temperature and increase with the increase of cellulose mass fraction, while the variations of non-Newtonian index were opposite. The non-Newtonian indices of the 2.5% and 3.0% cellulose/LiCl/DMAc solutions were closer to 1 at 20-60 ℃, meaning that the solutions have stable rheological properties. The structural viscosity indices of the 2.5% and 3.0% cellulose/LiCl/DMAc solutions were smaller, making them easier to spin, with 3.0% cellulose/LiCl/DMAc solution the optimal for electrospinning at room temperature.

Key words: cellulose, LiCl/N, N-dimethylacetamide, steady state rheology, dynamic rheology, electrospinning, spinnability
