Abstract
Methods are provided for producing a biaxially oriented nanoporous UHMWPE membrane. The method can include combining a petroleum jelly, an ultra-high-molecular-weight polyethylene (UHMWPE), and an antioxidant, forming a suspension, feeding the suspension into an extruder to produce a gel filament, pressing the gel filament to form a gel film, subjecting the gel film to an annealing temperature, and extracting the petroleum jelly from the gel film.
