“…To precisely determine the properties of smart materials and to thoroughly drive the action, the knowledge about its chemical structure, thus, its well-defined architecture, is mandatory [ 23 ]. Polymers with predetermined structures and branched architecture are widely provided by atom transfer radical polymerization (ATRP) techniques, especially with low catalyst concertation avoiding contamination of the final polymer product [ 24 , 25 , 26 , 27 ]. As a result of a precisely controlled equilibrium between active and dormant species driven by catalytic complex, the growth of polymer grafts is precisely controlled and the polymers with predetermined structure and properties are able to receive [ 28 , 29 , 30 , 31 ].…”
