Polyglycerol (PG) coated polypropylene (PP) films were synthesized in a two-
step approach that involved plasma bromination and subsequently grafting
hyperbranched polyglycerols with very few amino functionalities. The influence
of different molecular weights and density of reactive linkers were
investigated for the grafted PGs. Longer bromination times and higher amounts
of linkers on the surface afforded long-term stability. The protein adsorption
and bacteria attachment of the PP-PG films were studied. Their extremely low
amine content proved to be beneficial for preventing bacteria attachment
