NOVEL HYPERBRANCHED POLY(AMINE-ESTER) FILMS: PREPARATION, CHARACTERIZATION AND PROPERTIES

Received Date: 4 July 2005
Revised Date: 26 July 2005

Crosslinked film of hyperbranched poly(amine-ester) (HPAE) was prepared by crosslinking its terminal hydroxyl groups with glutaraldehyde (GA). Atom force microscope (AFM) and scanning electron microscope (SEM) reveals that they have smooth surfaces, dense and homogenous matrices. It was found that the water static contact angle is smaller than 41.7, the tensile strength is higher than 8.9 MPa, the elongation at break is higher than 5.1%, the swelling degree is higher than 42% in water, and the Bovine hemoglobin (Hb) adsorption is relatively low. These results indicate that the crosslinked HPAE films might have some potential applications in many areas.
