Functionalization of nickel-carbon nanocomposite with sodium polymethyl naphthalene sulfonate (C-3)

Effective use of metal-carbon nanocomposite (NC) dispersions in composite materials is a complex task. The results of experimental work on the functionalization of nickel-carbon nanocomposites (Ni/C NC) with sodium polymethyl naphthalene sulfonate (plasticizer C-3) for the modification of the cement matrix are presented. The article presents a comparative analysis of dispersions with different duration of ultrasonic treatment at different temperature conditions. It is revealed that solubilization and stability of the system is achieved at a time of ultrasonic treatment of 15 minutes and a heating temperature of 25 ° C. The infrared spectral analysis of compounds formed under the selected mode of obtaining dispersion was carried out. The obtained spectra indicate the substitution of sodium (Na) and the addition of the carbon structure of Ni/C NC to sulfur oxide (VI) SO 3- in a molecule of sodium polymethylsulfonate.
