A polyion-complexed polymeric monolayer was prepared by spreading monoalkyl maleate copolymer 1 on the aqueous poly(allylamine) subphase. Its monolayer properties have been studied by the surface pressure-area isotherm and fluorescence microscopy. The polyion-complexed Langmuir-Blodgett (LB) films on various substrates were characterized by FT-IR spectroscopy, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and ellipsometry. Two-dimensional cross-linking to form a polymer network was achieved by imide formation through heat treatment under vacuum along with concurrent removal of alkyl tails. From quantitative XPS analyses, the degree of cross-linking and skeletonization was determined to proceed for up to 77 % of the maleate unit under employed conditions. SEM observation of this film on a porous membrane filter showed that the four-layer film was sufficiently stable to cover the filter pore (0.1 μm). Immersion of this film in water and benzene did not cause any change in its appearance and in FT-IR spectra.
