(Phys.org) —A team of chemical researchers at the University of Melbourne in Australia has discovered a simple coating technique that uses nothing but tannic acid and iron ions. In their paper published in the journal Science, the team describes how they added tannic acid and iron ions to a water solution which resulted in the spontaneous creation of a thin film. The film, the group report, coats other materials that are put into the mix without the need for coaxing.
