An investigation into thiol–ene surface chemistry of poly(ethylene glycol) acrylates, methacrylates and CCTP polymers via quartz crystal microbalance with dissipation monitoring (QCM-D)

Thiol–ene reactions at surfaces have been investigated, comparing poly(ethylene glycol) (PEG) acrylate and methacrylate monomers with polymers made by cobalt catalysed chain transfer polymerisation (CCTP) using QCM-D. Thiolated surfaces were generated on silicon dioxide QCM-D sensors, with PEG monomers and polymers subsequently passed over the thiolated surface to study the thiol–ene reaction in the absence and presence of tris(2-carboxyethyl)phosphine, TCEP as catalyst.
