Fig. 5From: Immobilization of Gelatin onto Poly(Glycidyl Methacrylate)-Grafted Polycaprolactone Substrates for Improved Cell–Material InteractionsA linear relationship between the grafting yield (GY) of the P(GMA) brushes with the surface-initiated ATRP time was observed. The polymer chain growth from the PCL-Br surface could be controlled by varying reaction timeBack to article page
