Researchers Develop Color Changing Microspheres

DailyTech – Researchers Develop Color Changing Microspheres.

A team of researchers at the University of California, Riverside has been able to fabricate microscopic polymer beads that can change colors instantly with the application of an external magnetic field. The most interesting aspect of the color changing properties of the polymer beads is that the color change can be reversed.

The beads are technically magnetochromatic microspheres and have excellent structural stability according to the researchers. The microspheres are also very compatible with multiple types of dispersion media including water, alcohol, hexane, and polymer solutions. This allows the beads to retain their ability to be magnetically tunable in color when dispersed inside a variety of chemicals.
