In-situ Adsorption of Polymer Particles on Multi-wall Carbon Nanotubes Using Colloidal Techniques

In this study, we successfully developed the technique for in-situ adsorption of polymer particles on multi-wall carbon nanotubes (MWCNTs) using electrostatic interactions. First, we surface-modified the MWCNTs to disperse them in water through the hydration layers by poly(N-vinyl acetamide) (PNVA). Then, PMMA particles were adsorbed in-situ on the MWCNTs keeping good dispersion stability by electrostatic interactions. We believe that our study makes a significant contribution to the literature because when we also checked the existence of the electrical double layer around the dispersed MWCNTs modified with PMMA particles. The modified colloidal materials hold the potential to induce to the formation of PMMA resins to easily produce composite materials or serve as reinforcing fillers.123
