At the University of Chicago, researchers have found that a plasticizer long used to soften kitchen cling film can also make light-emitting polymers glow brighter and bend farther — dissolving a stubborn trade-off that has held back flexible electronics for years. By gently spacing apart polymer chains, dioctyl phthalate simultaneously quiets the interference that dims light emission and loosens the molecular structure that resists stretching. The discovery, led in part by an undergraduate researcher, suggests that the next frontier in wearable and body-integrated electronics may owe something
