2-十六烷氧基苯胺单分子膜原位还原制备纳米硒复合膜的研究

n amphiphilic aniline derivative 2-hexadecyloxyaniline(2-C16OAn) was successfully synthesized. Selenium nanoparticles were situ-reducted along with the formation of poly-C16OAn by spreading 2-C16OAn monolayer on the subphase of selenious acid aqueous solution, and the poly-C16OAn/selenium nanoparticles composite film was formed. The π-A isotherms of 2-C16OAn monolayer showed that the area per molecule of the monolayer obviously increased on the subphase of selenious acid aqueous solution compared with on the pure water subphase, which was due to the formation of poly-C16OAn and the inset of selenium nanoparticles into the film. The composite LB films composed of the poly-C16OAn/selenium nanoparticle were prepared by transferring the composite monolayers onto solid substrates, and characterized by transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The results indicated that selenium nanoparticles formed with a approximately uniform diameter of about 10nm, and arranged compactly with excellent monodispersion in the composite LB films.
