摘要: Carbon nanotubes are highly anisotropic due to their high aspect ratio, therefore it is very important align them in CNT/polymer composites. The extent of alignment can be easily studied by Raman spectroscopy. aligned perpendicular and parallel the polymer film application an external magnetic field polyvinyl butyral (PVB). FT-IR spectra these films suggest that there no chemical reaction between CNT butyral, but decrease G band intensity carbon suggests tangential site faces surface film, indicating a composite.
