The density of the topmost layer(ionosphere) is about 10% of your value.
False. By a long shot. Your premise is off to a bad start.

Do you know the conditions under which persistent contrails form? It has little or nothing to do with absorption of water.
It has everything to do with absorption.

if I read that correctly the .18mg/cm^3 exists at about 30,000m altitude - say 100,000 feet - where the density is given as 0.1841 kg/m3
Correct, i meant to say the Troposphere (Lower part of the atmosphere)
This is where the Aerographite would linger, increasing stratosphere density and pressure over time to become similar to the tropopause.

Topmost...bottommost. What's the difference, right?
But you're wrong again. 100,000 feet is well beyond the troposphere.
How can they do that? We are talking about temperatures below -40º. Ice forms, not water. Ice covers those particles. How can those particles absorb ice?
But these hygroscopic CCN do not sublimate or dissipate like contrail ice crystals do because they can continue to attract and absorb moisture from the surrounding area.
I thought not.
I can not provide you a link.
I have not come across any thing that indicates that the number or type of condensation nuclei have anything to do with persistence. Perhaps you can point me in the right direction.
the oxidation of sulfur dioxide and secondary organic matter formed by the oxidation of VOCs. The ability of these different types of particles to form cloud droplets varies according to their size and also their exact composition, as the hygroscopic properties of these different constituents are very different.
I thought not.
The number and type of CCNs can affect the lifetimes and radiative properties of clouds as well as the amount and hence have an influence on climate change [1] [2]; details are not well understood but are the subject of research. There is also speculation that solar variation may affect cloud properties via CCNs, and hence affect climate.

It would not affect the density of the stratosphere. That's like saying putting rocks in water increases the density of the water.

If you are intelligent enough to deserve the answer
