    Hi

    A looking for a material that I can use to cover a swimming pool with that can also be able to absorb/attract enough heat to be able to heat/warm up the water below it.

    Please help...

    Any black material, essentially...

    I would say a black material that is also a good conductor.

    i would say aluminium is one of the best (metal) conductors of heat..not sure that helps directly in answering your question..but maybe a flexible material containing aluminium would do the trick

    It might be this: Mini craters key to 'blackest ever black' - 06 February 2003 - New Scientist which according to Wikipedia has an emissivity of 0.996.

    Materials that absorb radiant heat well have a high emissivity. On this table charcoal is shown as having an emissivity of 0.96 which is very high, so it's a very good absorber.

    black polyethylene is black because it has carbon dispersed in it, does that give you a clue?
