LED-ing the way: A clean and convenient method to oxidize plastic surfaces for industry

Polypropylene (PP) is everywhere, being one of the most widely used plastics in human life. A versatile material, its naturally inert surface can be modified for specific applications. Researchers at Osaka University have now developed a convenient light-driven process for oxidizing PP without harmful waste. As reported in ChemComm, the process uses radicals to make the plastic react. The surface of PP bristles with methyl groups (–CH3), which constitute the side chains of the polymer. The strong C–H bonds in methyl groups make PP an unreactive material, which for many purposes is exactly what is needed. However, these bonds can be cleaved by the highly reactive chlorine dioxide radical, ClO2•. “In applications like printing and medical materials, plastics must be surface-modified,” explains study co-author Tsuyoshi Inoue. “Oxidizing C–H bonds is a textbook case in organic chemistry. With polymers, however, the risk is that anything strong enough to do this may also
