1/12/2020 · The PTFE-3-300 air cathode (with PTFE masses of 3.6 times that of acetylene black and at a heat treatment temperature of 300 C) was utilized as air cathode for an assembled Zinc-air battery, which delivered relatively small polarization loss and excellent rate 2

1/7/2021 · For the pristine membrane (ePTFE membrane without stretching), its average WCA is 109.7 , the value beyond 90 reflects a high hydrophobicity originated from the low surface tension of PTFE. For the stretched membranes, their WCA values are all dramatically increased and exhibit an incremental trend from M-4-300 to M-1-300.

Microporous Membrane Microporous membranes rely on diffusion through the air in the pores, a much faster process than solution-diffusion through PDMS, (Campbell Ritchie et al., 1996) and it can be seen from Table II.5.5.3 that a microporous membrane with a
