Sup /k/, /diy/nosaur here.
Genuine question: what material do they use to counter contemporary thermal cameras? It seems incredibly difficult. Must not be too absorbent or it will produce a black spot, has to warm up and cool down as the surroundings do, has to be moisture permeable, must not restrict movement, has to be weather resistant, must not degrade during washing, etc. Do they use multiple layers, nanoparticles? Some kind of engineered polymer? No, I am not trying to create one myself just bumped into a conversation the other day and I'm interested. Technical answers would be highly appreciated.

Forgot to say: I am thinking about clothing.
Here op already done for you

I had this coming I suppose. I did not know about this screencap. Fair enough, car windows do block IR and UV to some extent but it seems incredibly inconvenient to fashion clothing out of them. Anything else?
>>34332948
Not much will Anon I suggest VCR lining the clothes though if you have a swearer you could smash up the glass and put it on like tiles .
>>34333006
*sigh* okay, I get it, I'll just go to /b/ and go fuck myself while at it.
>>34333085
Really Anon IR isn't easy to counter try googling it first not much you can do
>>34332871
Your best bet is to walk around in a stupid amount of insulated clothing. I'm talking Mt Everest tier jacket and pants. Pray to god that your body heat won't make it through all the layers. But in reality you can't defeat it while still maintaining mobility and within a reasonable budget.

I have already tried google.
>>34333156
Reasonable budget? The question was merely theoretical, so let's assume I have all the money I need.
>>34332871
If I'm not mistaken, I'm pretty sure the military uses a dye in the uniforms since BDUs to lessen the IR signature. Thermal is a different story though I think.
The coatings aim to reduce NIR reflectivity to reduce visibility in NVGs, reducing visibility in thermal imaging is possible by insulating yourself, by wrapping foil around your body underneath your clothing for example, this is only really possible during light load in the winter though because you risk killing yourself by overheating otherwise. If you aren't willing to do that then you should choose to wear clothing that is as baggy as possible, so skin contact is minimised.

Thanks Anons. Please go on if you have the time.

If money is not an issue then I'm sure you come create some sort of closed circuit insulated moon suit that prevents any of you body heat fro leaking out and also has the ability to regulate the temperature of it's outer most layer to help blend with the background. The tech exists, it's just not practical. With modern IIR tech, a temp difference of only a few fractions of a degree can make you stand out against background heat levels. Much like Carl, even if you fully insulate yourself, you then created a "void" which is very easily detectable, so you need some way of melding with your background. This isn't too hard if you are alone in the middle of an empty desert, but when you add in various forms of vegetation and man made objects (which all radiate differently) it becomes almost impossible to mask yourself in a dynamic way.

It is already done by BAE Systems (Sweden) as far as I know. It's called Adaptiv and and it can mask, e.g. a tank, to have the IR cross-section of an SUV. Pic related.
