Article Synopsis
  • The study focuses on creating poly(n-butyl methacrylate) (PBMA) grafted polymer brushes on glass using a three-step atom transfer radical polymerization process.
  • Surface characteristics were analyzed using techniques like ToF-SIMS and ellipsometry, revealing how temperature affects the hydrophobicity and structure of the coating.
  • The findings showed that thicker PBMA coatings (86 nm) support better cell growth, resulting in a denser cell layer compared to thinner coatings (43 nm) and control glass, indicating the importance of coating thickness in cell culture applications.

The composition, thickness and properties of poly(4-vinylpyridine-co-oligo(ethylene glycol)ethyl ether methacrylate246) [P(4VP-co-OEGMA246)] copolymer grafted brush coatings attached to glass were studied in the dry and swollen states using ellipsometry. These measured data are in good agreement with predicted (estimated) changes in the amount of water, refractive index and thickness of the grafted copolymer brush coatings on swelling. For POEGMA brushes the thickness of the coatings on swelling at 20 °C can be more than double, in contrast to P4VP where those changes are insignificant.
