Molecular configuration of poly(MMA-r-nBA) coatings and proposed toughness mechanism. (a) Chemical structure of the poly(MMA-r-nBA) copolymer; the hard monomer (pMMA) and soft monomer (pnBA) units are indicated by yellow and green color, respectively. (b) ATR-FTIR spectra shows the comparison intensities of chemical groups in the MMA(black) and 50/50 poly(MMA-r-nBA) (red), respectively.
