Abstract

Albumin adsorption to a surface of fluorinated polyimide which was essentially created only by annealing treatment was investigated. After the polyimide surfaces were the polyimide surfaces were annealed, the morphology change of the surface was determined using atomic force microscopy and the surface properties were analyzed by contact angle measurements and X-ray photoelectron spectroscopy. It was found that albumin adsorption on the surface strongly depended on the annealing temperature and time and decreased with annealing. The amount of albumin adsorption to the polyimide annealed at 250degreesC for 100 hr was six-fold smaller than that of polystyrene and polydimethylsiloxane. A decrease of surface free energy due to a decline in thepolar and hydrogen bonding components and an increase in hydrophobicity onthe polyimide surface by annealing explain albumin adsorption results.
