Abstract Traditional mechanochemically controlled reversible‐deactivation radical polymerization (RDRP) utilizes ultrasound or ball milling to regenerate activators, which induce side reactions because of the high‐energy and high‐frequency stimuli. Here, we propose a facile approach for tribochemically atom transfer (tribo‐ATRP) that relies on contact‐electro‐catalysis (CEC) between titanium ox...
