Fig. 2. (a) Comparison of PSPMA brushes via CuBr-mediated SI-CRP by varying CuBr amounts. CuBrx represents the CuBr prepared by x g of CuBr (PMDETA 20 μL, polymerization time 30 min). (b) Influence of the PMDETA amount on the SI-ATRP of CuBr-mediated SI-CRP using CuBr0.025/CuBr0.1/CuBr0.5 (polymerization time for 30 min, D = 0.13 mm). (c) The growth kinetics of PSPMA brushes via CuBr0.025/CuBr0.1/CuBr0.5, respectively (PMDETA 10 μL, D = 0.13 mm). (d) Comparison of PSPMA brushes via CuBr-mediated SI-CRP at D = 0.13 mm and D = 0.49 mm.
