Preparation of Pressure Responsive Hollow Fiber Membrane by Melt-Spinning of Polyurethane-Poly(vinylidene fluoride)-Poly(ethylene glycol) Blends

摘要

A novel pressure-responsive hollow fiber membrane was prepared by melt-spinning of polyurethane-poly(vinylidene fluoride)-poly(ethylene glycol) (PU-PVDF-PEG) blends. The spun hollow fiber was treated by stretching, thermal treatment and secondary stretching, consequently becoming a hollow fiber membrane. The pore formation after each step was studied by observing the morphologies of the hollow fiber. The pore size and permeability of the membranes depended on the compatibility and the rheological behavior of the polymers as well as on the technical processes.View full textDownload full textKeywordsMelt, Membrane, Polyurethanes, Porosity, Pressure responsiveRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10426910903367378
