摘要：

Electrical conductivity, surface tension and viscosity of chitosan-based composite nanofibers are reported. 20 wt. % of chitin nanofibrils introduced into a chitosan solution leads to increase in viscosity of the mixture; the effect of shear rate becomes more pronounced. This phenomenon is caused by the formation of cluster structures involving filler particles, and by orientation of chitin nanofibrils under the action of shear stresses in electromagnetic field. Presence of chitin facilitated formation of nanofibers in electric field and led to significant decrease in the amount of defects.
