CNT Material Adsorbed onto Polymer Microspheres

The suspension polymerization method has become very popular because of its simplicity and the wide variety of monomers which can be effectively polymerized. Prepared spherical particles are applied in different areas of science and technology. It is also the case of polymer/CNT nanocomposite microspheres produced by the modified 

The interest in electrorheology has stimulated development of a new method of preparation of particles for such fluids. In this technique, polymeric microspheres are produced separately, which is 

The same experimental group continued the research (61) by adsorption of carbon nanotubes onto both PS and PMMA particles in the same method, with four different surfactants. Finally, the prepared PS microspheres with adsorbed nanotubes were sonicated in deionised water to test the durability of their association. It was found that individual tubes remain strongly adhered to the PS microspheres surfaces even after exposition to ultrasound. 

The amount of adsorbed carbon nanotubes onto PS and PMMA microspheres was measured (61), and the results are presented in Table 8.2. It was found that the type of surfactant considerably affects the amount of adhered CNT. As can be seen, the best results, i.e. the highest CNT amount, were achieved for CTAB and NaDDBS. The influence of the used surfactants and polymer
