Study On Functional Rare Earth Containing Polymer-Clay Composites

In this study, three types of copolymer modified Montmorillonites( Eu(Phen)(BA)₂AA-co-MBDAC ) -MMT, ( MBDAC-co-4-VP ) -MMT, andEu(Phen)(BA)₂AA-co- (MBDAC — MMT) were synthesized and characterizedby IR, XRD, DTA-TG and fluorescence spectrometer etc. The results arepresented as follows:(1) The fluorescent property analysis show that the Montmorillonites modified with rare earth polymers have preferably fluorescent emission at 615nm, while the rare earth polymers exhibit most strong emission when the molar ratio of Eu(Phen)(BA)₂AA to MBDAC is 1/4. (2) The montmorillonites modified with oligomeric quaternary ammonium (MBDAC-co-4-VP) were prepared through cation exchange . Fluorescent properties of the modified montmorillonites and the oligomeric quaternary ammonium were studied. The results show that the fluorescent properties of the copolymer can be controlled by altering the ratios of the monomers.
