Abstract

A hydrophilic, non-ionic surface was prepared by grafting polyethyleneoxide (PEO) onto polyethylene (PE) and mica substrates. Monofunctional PEO-aldehyde was coupled by means of reductive amination to primary and secondary amino groups of polyethyleneimine (PEI) adsorbed on oxidized polyethylene (PE) and on mica. Optimum values of the reaction parameters influencing the reductive amination in this heterogeneous system were sought in order to achieve complete coverage of the surface by covalently linked PEO chains. Carrying out the coupling reaction at 60 °C, pH 6 and ck2so4 over 40 h resulted in a PEO surface characterized by a maximal ESCA - C-O-/-CH2-ratio and, simultaneously, complete wetting by water. A PEO surface with a high degree of coverage was also obtained by means of adsorption from solution of a PEO-amine compound on mica.
