Abstract:
Tw o kinds of org ano-m ontm or illonite ( OMMT) were prepared from MMT by ion exchange w ith two different o rganic intercalation. The OMMT w as characterized by FTIR, XRD and TGA. The resu lts show ed tha t two o rganic interca lation had inte rca la ted into the layers o fMMT and the spac ing o f layers o fMMT had increased by mo re than 4nm. The OMMT m odified w ith org an ic silicon in terca lation had larger spac ing o f laye rs. TheTGA ana lysis indicated that two kinds o f OMMT had exce llent property o f therm al stab ility. The onset therm a l decomposition tem pe ra ture w as above 200e , wh ich w as re lated to the structure o f interca lation and the env ironm ent. W e had a pre lim inary study on the app lication o f the OMMT in the silicone em ulsion.
