【 摘 要 】

The use of formaldehyde and phenol as raw materials, under the acidic catalyst, the high temperature polymerization produces a thermoplastic phenolic resin. At low temperatures, modified nickel sulfate is added to synthesize Ni-modified thermoplastic phenolic resin, and carbonization is carried out at high temperature. The effects of carbonization temperature, carbonization heating rate and nickel doping amount on the carbonization product are investigated. Experiments have shown that the optimal conditions for the Ni-modified thermoplastic phenolic resin. The molar ratio of formaldehyde to phenol is 0.85, oxalic acid accounts for 2% of the mass of phenol. The reaction temperature is 100° C. The reaction time is 2 h. The molar ratio of iminodiacetic acid to phenol is 0.03, and the molar ratio of nickel sulfate to phenol is 0.04. The combined temperature is 60°C and the chelating time is 40 minutes. The pyrolytic carbon of the nickel modified phenolic resin is characterized by field emission electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The results show that the best carbonization temperature is 10 °C/min at 1100°C for 3 h, and a large number of carbon nanotubes are formed in the pyrolytic carbon.
