Abstract

Continuing with our previous work, in which CdSe nanoparticles were functionalized with polystyrene (PS) brushes (CdSe-PS) by the grafting through method, nanocomposites were prepared by adding them to a poly(styrene-b-butadiene-b-styrene) (SBS) triblock copolymer. After characterizing CdSe-PS nanoparticles obtained at different polymerization times of 3, 5, and 8 h by means of thermogravimetric analysis and gel permeation chromatography, CdSe-PS nanoparticles obtained after 5 h of polymerization (CdSe-PS(5h)) were chosen as the most adequate for the generation of nanocomposites. Atomic force microscopy (AFM) was used for morphological characterization of SBS/CdSe-PS(5h) nanocomposites. AFM images showed a good dispersion of the nanoparticles in the block copolymer, with the placement of the nanoparticles in the PS domains due to the improved affinity obtained by their functionalization with PS brushes.
