Действие малых добавок углеродных нанотрубок с исходной и окисленной поверхностью на механические показатели и стойкость олиэпоксидного композита

Abstract

It is shown that the introduction of 0.1 - 2 wt% carbon nanotubes (CNT) leads to the formation of ferrous compositions with aggregate filler. Thus starting from 1 wt% inhomogeneous distribution leads to a sharp increase of viscosity and deterioration of operational properties. It is established that the introduction of 0.1 - 2 wt% CNT with the original and the oxidized surface does not allow to increase the studied strength properties (compressive and Flexural). However, the introduction of CNT allows you to increase resistance in chemically aggressive environment (concentrated nitric acid) and fire-resistance composites (growth with increasing concentration of CNT). These effects are better observed for CNT oxidized surface.
