Abstract: Four kinds of CA/O-MMT composite fibers were prepared from highly volatile solvent system by electrospinning using DCM/acetone as solvent.The adsorption performance of fibers were investigated.The conductivity of solutions were measured by a conductivity meter,the viscosity of solutions were measured with a viscometer.CA/O-MMT fibers surface morphology were studied by scanning electron microscopy (SEM),the composite structure between CA and CA/O-MMT was analyzed and confirmed by FT-IR.The distributions of O-MMT in the fibers were studied by TEM.The adsorption of dyes was measured by ultraviolet and visible spectrophotometer.The results showed that,with the increasing ratio of O-MMT,the fiber diameters were decreased,the beads were occurred,but the adsorption performance of fibers was improved.The increasing of temperature was benefit to the adsorption performance,while the acidic condition was bad for the adsorption performance.
