## imaging
When imaging in the SEM without sputter coating the material you disappear if focus too closely (either blowing away or disintegrating from the electron beam - hopefully this isn't damaging the SEM??) the same way that the dust particles on the Gerson N95 did. So I added a 20 nm gold layer to the top of each layer.
### observations
- the outer layers look like some sort of pressed pulp, not as fibrous and stringy as the N95 masks
- the middle layer looks more like the N95 mask outer layer, except with smaller fiber width
