Study of Mechanical and Optical Properties of Aligned Multiwall Carbon Nanotubes in Poly(methyl methacrylate) Matrix in Electric and Magnetic Fields

In this paper, polymer nanocomposite thin films were prepared by solution casting method using poly(methyl methacrylate) as a matrix and multi-walled carbon nanotubes as a filler. The structural, morphological and mechanical properties of nanocomposites have been characterized by Raman and UV–Vis spectroscopy, SEM and DMA. The behavior of the nanocomposites under electric and magnetic fields is discussed in details. The elastic modulus of the nanocomposites in electric field is increased comparing with magnetically and randomly aligned polymer matrix.
