Modulation of flexo-rigid balance in photoresponsive thymine grafted copolymers towards designing smart healable coating

Abstract: Photo-crosslinking using [2 + 2] cycloaddition in thymine grafted low viscosity polymer generates flexorigid domain to result self-healing polymer with increased hydrophobicity for potential use as smart coating material.

“…This was in agreement with the fact that the position of coumarin within the hydrophobic block significantly influenced the photodimerization efficacy owing to the steric factors. This led us to conclude that the position of coumarin is an important factor in determining photodimerization efficacy, thereby controlling the eventual chain collapse in the couramin-tethered polymers as previously reported by us. , Furthermore, the DLS experiment exhibited a reduction in hydrodynamic diameters upon UV B irradiation due to the chain collapse in the hydrophobic blocks of polymers P- b -C- b -F , P- b -F- b -C , and P- b -C-r-F , as corroborated from intensity, volume, and number data (Figures E,F and S11). Moreover, % compaction was found to depend on the position of coumarin in triblock polymers owing to differential %PD efficacy.…”
