Then the researchers embedded the columns in a polyallylamine matrix. They built up the material by repeating the process, adding more layers of the polymer-impregnated columns on top of each other. The material has a collection of properties—stiffness, density, and vibrational damping—that are similar to or better than those of tooth enamel and that haven’t been combined in one synthetic material before.
