Nanomaterials Based on Polyanilines and MoSe

Polyaniline, poly( N-methyl aniline), poly(2-ethyl aniline) and poly(2-propyl aniline) were intercalated into layered molybdenum diselenide by using the exfoliation/restacking property of LiMoSe. MoSe was reacted with n-butyllithium to form LiMoSe. The LiMoSe was exfoliated in N-methylformamide (NMF) with the help of ultrasonication which lead to the formation of single layers of MoSe. Addition of NMF solutions of the polymers to the exfoliated layers resulted in their intercalation into MoSe. The products were characterized by powder X-ray diffraction. Fourier transform infra-red spectroscopy, and four-probe van der Pauw technique electrical conductivity measurements are reported here for the first time.
