RUIZ LEON, DOMINGO; GALDAMEZ, ANTONIO  e  MANRIQUEZ, VÍCTOR. INTERCALATION OF POLYETHYLENE OXIDE IN LAYERED THIOPHOSPHATE OF BI AND SB. J. Chil. Chem. Soc. [online]. 2008, vol.53, n.2, pp.1477-1479. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072008000200006.

The intercalation compounds Li0,43(PEO)2.4(H2O)1.4K0.57BiP2S6 and Li0.38(PEO)2.1(H2O)1.6K0.62SbP2S6 have been synthesized by the insertion of polyethylene oxide PEO in LiKMP2S6 (M=Bi, Sb), that contained Li+ and K+ exchangeable cations in their interlayer space. The polymer PEO is able to associate interlayer Li+ cation modifying the ionic conductivity of pristine phases. These intercalation compounds constitute a new family of intercalates in the thiophosphate of Bi and Sb with Polyethylene oxide as guest species. They have been characterized by powder X-ray diffraction, FTIR-Raman, DTA/TGA analysis and electrical conductivity measurements. The studied nanocomposite shows values of electrical conductivity (σi) of about 10-6 Ω-1 cm-1 at room temperature.
