Surface modification of polystyrene by low energy hydrogen ion beam
چکیده انگلیسی

Polystyrene was modified by low energy hydrogen ions in ultrahigh vacuum. The modified surfaces were analyzed in situ by x-photoelectron spectroscopy and ex situ by atomic force microscopy. Results revealed that 10 eV H+ ion bombardment on polystyrene produces a cross-linked network film, while the polymer backbone remains intact and undesirable impurity (such as nitrogen, oxygen, etc) incorporation is eliminated. The as-prepared network film is just about 5–6 nm thick, but is highly resistant to chemical solvent. However, when 100 eV H+ ion bombardment is used, the aromatic rings are seriously damaged and the surface of organic film is etched. This work suggests a new route to the preparation of ultrathin polymer network films.
