Influence of Material Properties on Scratch-Healing Performance of Brush Copolymers that Undergo Thermally Reversible Crosslinking |
| 초록 |
Scratch-healing brush copolymers (BCPp-DAs), each consisting of a poly(methyl methacrylate) backbone, oligo-caprolactone urethane bristles, and a DA adduct unit, were successfully synthesized and shown to be capable of undergoing thermally reversible crosslinking. The synthesized polymers were coated on steel substrates to investigate the influence of their material properties on their scratch-healing performance. The reversible formation of crosslinked and de-crosslinked structures of the BCPp-DA coatings at Diels Alder (DA) and retro-Diels Alder (rDA) reaction temperatures was demonstrated using FT-IR spectroscopy, differential scanning calorimetry (DSC), oscillatory rheology, and nanoindentation (NI). The scratch-resistance and healing performances of the BCPp-DA coatings were evaluated quantitatively using a scratch test machine equipped with an optical microscope (OM) and an atomic force microscope (AFM). |
