Transmission electron microscopy polystyrene nanocomposites

In addition, the recycled expanded polystyrene and TiOi were mixed via the solution method [67] the transmission electron microscopy images indicated that the nanocomposites had an average particle size of 6-12 nm. The nanocomposite samples had greater polymer stability and higher discoloration efficiency for aqueous methylene blue solutions, due to the incorporation of TiOi nanoparticles. 

UV-visible spectrophotometer over wavelengths ranging from 200 to 800 nm on films with thickness of 200 [xm was used by Cipriano et al. [25] to show that the importance of particle size by doing the fractionation of a montmorillonite before preparing a polystyrene nanocomposite. The objective was to eliminate the microscale aggregates. By confirmation of the absence of large particles by transmission electron microscopy images on the nanocomposite prepared with the fractionated samples, it was clearly evident that the best transparency was reached for the fractionated clay.
