Using LED as a light source, researchers at Osaka University have now developed a convenient light-driven process for oxidizing polypropylene (PP) without harmful waste. The research team used radicals to make the plastic react. Scholars chose an LED lamp as the light source photo-chemically activate radicals for breaking down the chemical bonds which make plastic unreactive and hard to decompose. "In applications like printing and medical materials, plastics must be surface-modified," explained Tsuyoshi Inoue, co-author of the study. "Oxidizing C-H bo...
