A team of chemical engineers from the University of Melbourne, led by Dr. Luke Connal, have discovered a way to 3D print smart polymers that highly functional, as well as cheaper, cleaner, and more accessible than what’s available on the market. These smart polymers are designed to undertake a chemical reaction that will perform a function in a specific environment, such as ridding the environment of toxins. In addition, the research team also produced flow regulation device with a smart polymer valve that that opens and closes to control the flow rate of water dependent on the pH of the flowing water.
