Abstract
Contrast enhancement for magnetic resonance imaging of polyethylene films is achieved by surface amination with hydrazine plasma treatments followed by covalent attachment of a cation chelator, diethylenetriaminepentaacetic acid (DTPA), which is then allowed to complex with gadolinium(III) ion. First, we investigated the effects of plasma conditions, that is, plasma treatment time and power. Polyethylene surfaces after the treatment to link primary amine groups, attachment of DTPA via amide linkage, and complexation with Gd3+ were characterized by X-ray photoelectron spectroscopy, water contact angle, attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), and atomic force microscopy. A maximum surface density of primary amine group is found by the plasma treatment at low power (15 W) and short treatment time (5 min) under the continuous wave conditions. ATR-FTIR confirms that the amine and amide groups are formed on the PE surface after the hydrazine plasma treatments, which is a...
