STUDY ON HOMOGENEOUS BRAIDED TUBE REINFORCED POLYACRYLONITRILE HOLLOW FIBER MEMBRANES


Abstract:
Homogeneous braided tube reinforced polyacrylonitrile (PAN) hollow fiber membranes which contained hollow braided tube and separation surface were prepared by concentric circles spinning method.The braided tube was prepared by the two-dimensional braided technique using PAN fibers.While the separation surface was obtained by non-solvent induced phase separation method with PAN as the polymer matrix,dimethyl sulfoxide (DMSO) as the solvent,and polyethylene glycol (PEG) as the pore-forming agent.Results showed that the structure of separation surface was similar to asymmetric membrane.The casting solution would penetrate into the voids among fiber bundles of the braided tube.As the braided pitch increasing,the thickness of separation surface decreased,which induced the promotion of the membrane water flux.There was no obvious influence of casting solution penetration on the membrane permeability.The breaking strength of braided tube was up to 100 MPa.Water bath vibration,ultrasonic vibration and the same axial tension force were utilized to investigate the interfacial adhesion between separation surface and braided tube of homogeneous and heterogeneous braided tube reinforced hollow fiber membranes.The results showed that the interfacial adhesion of the homogeneous one was superior to that of the heterogeneous one.

Key words:Homogeneous reinforced, Two-dimensional braided tube, PAN, Hollow fiber membrane
