Multiblock copolymer brushes have broad application in thermoplastic elastomers, drug delivery, porous materials, and nanolithography due to their unique structure and properties. In this research, a novel multiblock copolymer brush (PHEA-g-PEG)(x)-co- (PEG(23))(y) was synthesized by combining the efficient double strain-promoted azide-alkyne cycloaddition (DSPAAC) and copper-catalyzed azide-alkyne cycloaddition (CuAAC) click reactions. The gel permeation chromatography (GPC), proton nuclear magnetic resonance spectrometer (H-1 NMR), Fourier transform infrared spectroscopy (FT-IR), and atomic ...
