I've got a project I'm interested in. Essentially its modifying a melamine foam so its thermal conductivity is at least halved. Was thinking some type of buckyball filler in the matrix might be a ticket. However someone pointed out it maybe a worry about how it would affect the cell structure/stability. So I was thinking (and this is something I do too often) that perhaps you could coat the bucky balls in something that would enhance integration into the matrix of melamine-formaldehyde bonds.
