Polyolefin Ion Membranes in Electrochemical Cells

  1. Jan 11, 2017 #1
    Hi, I was wondering if any old polyolefin membrane would work as a separator in an electrochemical cell, or if there is only a special "porous" version. For example, would a grocery store sack (polyethylene) work. It is my understanding that polymers of this sort are naturally porous, resembling hairballs on a micro scale. Thanks.

    I wasn't sure if those characteristics had to be intentionally synthesized into a production of polyethylene, or if they were just naturally there as part of the process. The article mentions simple mechanical stress to induce porosity. I'll try and find a way to test it. Thanks.
