MoSe2 has been encapsulated with a variety of guest species. This was achieved by first treating the MoSe2 with an excess of n-BuLi to form the lithiated phase of MoSe2 (LixMoSe2). The LixMoSe2 exfoliates readily in water or NMF to yield single layers of MoSe2. Addition of solutions of polymers, org...

Poly[oxymethylene-(oxyethylene)] has been inserted in the gallery space Of MoS2 by using the exfoliation/re-stacking properties of LiMoS2. The resulting intercalation compound shows enhanced electronic conductivity due to a structural transformation of the MoS2 framework. The material was also chara...

In this paper we report on the synthesis and characterization of a few alkyl substituted polyanilines into VOPO4. This was achieved by treating the monomers with the highly oxidizing host VOPO4 center dot 2H(2)O. The monomers polymerize and simultaneously insert in between the layers of the host sys...

Polyaniline, poly(ethylene oxide), poly(propylene glycol), poly(vinylpyrrolidinone), methyl cellulose, polyethylenimine, polyethylene, and Nylon-6, were encapsulated into MoS2. Electrical conductivity and thermoelectric power measurements of pressed pellets of (PEO)(0.92)MoS2 and (Polyaniline)(0.35)...

In this paper we report on the insertion of polypyrrole into layered graphite oxide. This was achieved by using the exfoliating and re-stacking properties of the host. The resulting intercalated product was characterized by powder X-ray diffraction, FT-IR spectroscopy, thermogravimetric analysis and...

Intercalation compounds of polyethylene oxide, polyvinylpyrrolidone, methyl cellulose, poly[oxymethylene-(oxyethylene)] and poly[oligo(ethylene glycol oxalate)] into graphite oxide (GO) have been synthesized. The forces of attraction between the polymers and GO are primarily dipole?dipole and/or hyd...

In this paper, we report on the direct intercalation of polypyrrole into MoS2. This was achieved by first synthesizing LiMoS2. The LiMoS2 was exfoliated by reaction with deionized water. Addition of a colloidal Suspension of polypyrrole in NMF to the single MoS, layers results in flocculation with e...

Polyaniline (PANI), poly(N-methyl aniline) (PMA), poly(ethyl aniline) (PEA) and poly(propyl aniline) (PPA) were synthesized in their salt form, and then characterized by FT-IR spectroscopy and charge transport measurements. The solubility of the polymers was tested in a variety of solvents and N-met...

Herein we report on the intercalation of polyaniline, poly(2-ethylaniline), and poly(2-propylaniline) into graphite oxide. This was achieved by taking advantage of the exfoliation/reconstruction properties of the layered host. The resulting intercalates were characterized by powder X-ray diffraction...
