(MIT: Cambridge, MA) -- Scientists often seek new materials derived from polymers. Rather than starting a polymer search from scratch, they save time and money by blending existing polymers to achieve desired properties.

But identifying the best blend is a thorny problem. Not only is there a practically limitless number of potential combinations, but polymers also interact in complex ways. So, the properties of a new blend are challenging to predict.
To accelerate the discovery of new materials, MIT researchers developed a fully autonomous experimental platform that can efficiently identify optimal polymer blends. The closed-loop workflow uses a powerful algorithm to explore a wide range of potential polymer blends, feeding a selection of combinations to a robotic system that mixes chemicals and tests each blend. Based on the results, the algorithm decides which experiments to conduct next, continuing the process until the new polymer meets the user’s goals.
