AI Thread Summary
The discussion revolves around the search for materials that can self-decompose in anaerobic conditions, specifically in the context of space applications where vacuum conditions are present. The original poster seeks materials that can lose mass and effectively "vanish" over a reasonable timeframe. Participants clarify the distinction between anaerobic conditions and vacuum, noting that while anaerobic decomposition can occur with certain polymers like cellulose and aliphatic polyesters, vacuum is not conducive to life and thus complicates the decomposition process. The goal is to find materials that can decompose quickly once exposed to space, potentially within days. Suggestions include blending nutrients with polymers to enhance decomposition, although the feasibility of such materials in a vacuum environment remains a key concern. The conversation emphasizes the need for practical solutions that align with the unique challenges of space conditions.

Dear all,

Does anyone of you know the name of some materials that self-decompose in anaerobic conditions (spontaneus decay possibly) in a reasonable time? I'm researching a possible application for this kind of things.

Thank you in advance,

Regards,

D.

Define "self-decompose".
 
I need something that, in anaerobic conditions, loses mass from its solid phase (i.e. turns into gas or is used by some sort of micro-organisms as nutrient) in a reasonable time:

basically I'd like my material to "vanish" after some time (again: in anaerobic vacuum conditions!)

I don't know if anything like this exists, but if anyone has some pointers I'd be grateful.
 
Nuclear fuel?
 
Anaerobic is not vacuum. Which is it... anaerobic or vacuum? Anaerobic decomposition can occur with any number of polymers such as cellulose (or rayon), aliphatic polyesters, aliphatic nylons and so forth. If nutrients are blended with these polymers, you have a head start on the process.
On the other hand, vacuum isn't compatible with life, anaerobic or otherwise.
 
I apologize in advance if I say something stupid and/or confusing, I'm a computer scientist, not an expert in the field, but I'm working in a team that still has to do its first meeting and I wanted to come with some ideas already :)

The "decomposition" is supposed to work in space (the human-made satellite orbits), so technically I think that vacuum is more of a precise description than anaerobic.

@chemisttree: You said that vacuum is not compatible with life, but I don't need my agents to live for a long time, just as much is required to consume my material: basically I want to bring a board of material in space in any desired stability condition, and once I put it "outside" my ship, it has to self-decompose in a matter of days possibly. Do you think this is possible?

@Schliere: could you elaborate your suggestion a little bit?

@All: Don't forget that you are talking to a dummy of the field :D Thanks in advance for your time and cooperation!
