   > Hello, new here and all that jazz. I'm working on a space opera setting and   
   one of the things I'm curious about are the materials that could be used to   
   make a radiator. I have an idea on how warship radiators operate, but I'm   
   trying not to break more    
   rules than I need to.

   can be rigid in one set    
   of circumstances, but flexible in another? Is this even plausible?   
      
   First of just want to refer you to Atomic  Rockets, if you haven't already   
   found it.

   No current day materials can work like you want at the temperatures you need   
   less the radiator becomes ginormous. You basically want a thermarest made from   
   carbon-tungsten composit.   
      
   A couple of options   
   Graphene can be made from very thin strips that can be rolled up, and they   
   have most excellent heat conducting properties. But I don't know if it is   
   enough without some fluid circulation.   
      
   A droplet radiator can be folded in too, but you cant do any turning while   
   using it, or you loose you radiator fluid.
