Modification of polyethylene with Pluronics F127 for improvement of blood compatibility.

In order to improve blood compatibility of polyethylene (PE) film, the Pluronics F127 additives in the PE film were then crosslinked to be stably entrapped in the PE matrix. The crosslinking was done by free radicals produced from the decomposition of dicumyl peroxide (DCP) in the film through heating (120 degrees C). Surface properties of the Pluronics F127 additive-containing PE films were investigated by Fourier transform infrared spectroscopy (FTIR), electron spectroscopy for chemical analysis (ESCA) and water contact angle (WCA) measurements.
