| 英文摘要 | A series of superabsorbent composites were synthesized by copolymerization reaction of partially neutralized acrylic acid on unexpanded vermiculite (uvmt) micropowder using n,n'-methylenebisacrylamide (mba) as a crosslinker and ammonium persulfate (aps) as an initiator in aqueous solution. and the samples were further characterized by means of fourier-transform spectroscopy (ftir), scanning electron microscopy (sem), transmission electron microscopy (tem), x-ray diffraction (xrd) and thermogravimetric analysis (tga). the effects of vermiculite content on water absorbency were studied. swelling behaviors of the superabsorbent composites in various cationic salt solutions (nacl, cacl2, and fecl3) anionic salt solutions (nacl, na2so4 and na3po4) and ph solutions were also systematically investigated. results obtained showed that the equilibrium water absorbency increased with increasing uvmt content and the concentration of 20 wt.% clay gave the best absorption (1232 g/g in distilled water and 89 g/g in 0.9 wt.% nacl). data achieved also suggested that the water absorbency in various saline solutions decreased with an increase in the ionic strengths of these solutions. and it was found that at a higher ionic strength (>1 x 10(-3) m), the water absorbency in monovalent cationic solutions was higher than those in multivalent cationic solutions. however, at the same ionic strength (>1 x 10-3 m)7 the effect of three anionic salt solutions on the swelling has the following order: nacl < na2so4 < na3po4.
