| 英文摘要 | graphite oxide (go) nanoplatelets with a thickness from 0.8 nm to 2 nm were prepared using a modified hummers method. by employing go nanoplatelets as nanofillers, poly(acrylic acid)-go superabsorbent nanocomposites were synthesized by a facile solution polymerization of acrylic acid monomers using n,n'-methylenebisacrylamide as cross-linker and ammonium persulfate as initiator. the well-dispersed go nanoplatelets in the polymer networks results in a significant improvement in absorbencies both in distilled water and saline solutions. with only a very low loading of go in the superabsorbent nanocomposite, for example 0.073 wt%, its water absorbency reaches up to 508 g g(-1), which is nearly as twice that of the poly(acrylic acid) (paa) superabsorbent. the superabsorbent nanocomposite also exhibits a superior water-retention ability compared with the control under the same conditions. our study may provide a new way for the development of novel, go-based superabsorbent nanocomposites with improved absorbency and may find a variety of useful applications. |
