Study of the Effect of Epoxy Reinforcement with C60 on the Rheological and Adhesion Properties

Abstract

Cold curing was used to evaluate the rheological properties of epoxy resin which was reinforcedwith fullerene (C60) 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 relationshipbetween resin viscosity and resin with nanoparticles temperature dependency, the effect offullerene reinforcements on the viscosity of the constituent epoxy-polymer compositions wasevaluated. We steadied how the complex viscosity changed with time when adhesivecompositions doped with C60 at various concentrations polymerized. By changing theconcentrations of fullerenes, the time to reach the gel-point was determined for the mixturesand materials used. It was observed that the reinforcement at the beginning of the mixture withreinforcement 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 thepolymer is doped with fullerenes at 0.15 wt.% and decrease when the polymer is without filler
