Nature produces a startling array of patterned materials, from the sensitive ridges on a person’s fingertip to a cheetah’s camouflaging spots. Although nature’s patterns arise spontaneously during development, creating patterns on synthetic materials is more laborious. Now, researchers reporting in ACS Central Science have found an easy way to make patterned materials having complex microstructures with variations in mechanical, thermal and optical properties—without the need for masks, molds or printers.
