Hollow fiber membranes and methods for forming same
DA Bhandari, PJ McCloskey, PE Howson… - US Patent …, 2016 - Google Patents
The invention provides improved hollow fiber membranes having at least two layers, and
methods for forming the same. The methods include co-extruding a first composition, a sec
ond composition, and a third composition to form a dual layer hollow fiber membrane. The
first composition includes a glassy polymer, the second composition includes a polysi
loxane; and the third composition includes a bore fluid. The dual layer hollow fiber
membranes include a first layer and a second layer, the first layer being a porous layer …
