Paper Title:
Influence of Dope Concentration on Morphology And Properties of Cellulose Hollow Fiber Membranes Prepared from Cellulose/[Amim]Cl Dope Solution
  Abstract

Basing on a L-S phase inversion method, cellulose hollow fiber membranes were spinned using room temperature ionic liquid 1-allyl-3-methylimidazolium chloride ([Amim]Cl) as solvent. The concentration of cellulose/[Amim]Cl solutions (dope) was varied from 6 to 9wt% by an increment of 1wt%. Effects of the dope concentration on the hollow fiber membranes structure and properties were investigated. Inner- and outer- surfaces morphology of the prepared membranes were observed using field emission scanning electron microscope (FESEM). Besides, various properties of the membranes, including apparent viscosity, pure water flux (PWF), retention rate (Rt), equilibrium water content (EWC), ultimate tensile strength (UTS) and elongation at break (Eb) were also tested. The results induced that, with the increase of dope concentration, the both surfaces showed more regular. Pure water flux and equilibrium water content of the membranes decreased with a increasing dope concentration, properties of retention rate, ultimate tensile strength and elongation at break showed a increased tendency oppositely.
