Common Bricks Turned Into Supercapacitors?
Scientists at the D’arcy Laboratory Department Of Chemistry at Washington University in St. Louis have come up with a novel way to take a basic common red building brick and turn it into a supercapacitor by coating them with a special conductive polymer.
Converting a brick into a “smart brick” is possible because a red brick is, in and of itself, red because of the hematite that is within the brick used as a red pigment. When the brick is solidified by heating, it becomes microporous which is a perfect structure for depositing PEDOT – poly(3,4-ethylenedioxythiophene) nanofibers through another controlled process called oxidative radical polymerization.
Once this is achieved, the transformation is complete and “voila!” you have a relatively cheap and accessible supercapacitor.
