Síntese e caracterização dos nanocompósitos K0,1(PEO)xMoS2 (X= 0,5; 1,2)

Síntese e caracterização dos nanocompósitos K0,1(PEO)xMoS2 (X= 0,5; 1,2)

The reaction of an aqueous solution of poly(ethylene oxide) (peo - mw 100.000) with a neutral aqueous suspension of single layers of MoS2 was studied. The single layers aqueous suspension was prepared by first intercalating lithium (using n-Butyllithium in n-hexane) and reaction of these ternary compound with water under ultrasound stirring. The suspension was washed several times with water until neutral pH. The suspension was mixed with the PEO aqueous solution in the presence of KCl. Two single phase compounds were obtained with the expansion of 4,8 and 9,0Å, attributed to the solvation of the intercalated potassium cations with mono and double layers, respectively.
