Journal of Wuhan University of technology(Materials Science) 2009年第1期24卷 68-71页

作者：柳华实葛曷一 institute of Materials Science and engineering University of Jinan

Ethylacetoacetate （EAA） was mixed with aluminum sec-butoxide （ASB） in aqueous medium. The molar ratio among aluminum sec-butoxide, water, and ethylacetoacetate was 1∶200∶1. Water diluted nitric acid was added into the mixture until it finally transformed into transparent solution. TEM analysis showed that the surfaces of the colloidal particles with EAA were not as clean as those without EAA, implying the formation of a surface modification layer around the colloidal particle. The IR spectra analysis revealed that with the addition of EAA two characteristic peaks of EAA at 1 731 cm-1 and 1 642 cm-1 associated with C=O stretching vibrations were red-shifted to 1 619 cm-1 and 1 530 cm-1, respectively, indicating the occurrence of the chemical modification reaction among the C=O bonds of EAA and the surface Al-OH bonds of the particles. Furthermore ,i t was con-firmed by UV spectra analysis that the UV absorption band of EAA underwent 26 nm of red-shift as a result of the formation of the six-membered ring of the complex between ethylacetoacetate and ASB. It was examined that the chemical modification could be photolyzed by the UV illumination with a wave-length shorter than 270 nm due to the excitation of π-π＊ transition in the complex.
