“…The general trend in polymerization time is shown in Figure 3. It is shown that doping of the binder with fullerenes to a concentration of 0.15 wt % leads to an increase in Young's modulus with its subsequent decrease to the level of the binder without filler [9]. In general, viscosity changes occur throughout the complex process of epoxy resin curing.…”

“…Above the percolation threshold, the system's behavior is undefined. In a number of researchers [8][9], it was shown that with an additional rise in the filler concentration, the change in the properties of the composite material is less intense. However, a number of experiments have shown that with a further increase in the concentration of fullerenes (or nanotubes), the properties of the polymer do not improve, but become the same (as before the introduction of the modifier) or even deteriorate [10,11].…”

Cold curing was used to evaluate the rheological properties of epoxy resin which was reinforced with fullerene (C 60 ) at different concentrations (0, 0.07, 0.11, 0.16, 0.25, 0.33, and 0.66 wt%).The kinetics of changes at complex viscosities was studied, by investigating the relationship between resin viscosity and resin with nanoparticles temperature dependency, the effect of fullerene reinforcements on the viscosity of the constituent epoxy-polymer compositions was evaluated. We steadied how the complex viscosity changed with time when adhesive compositions doped with C 60 at various concentrations polymerized. By changing the concentrations of fullerenes, the time to reach the gel-point was determined for the mixtures and materials used. It was observed that the reinforcement at the beginning of the mixture with reinforcement changes with the time curing of the composition at a concentration of 0.16 wt.%, the maximum effect (30%) is achieved. The Young's modulus is shown to increase when the polymer is doped with fullerenes at 0.15 wt.% and decrease when the polymer is without filler.
