Direction sensitive deformation measurement with epoxy/CNT nanocomposites

چکیده
Nanoparticles can be used for the introduction of functional properties into polymer matrix systems. In epoxy matrix systems low percolation thresholds can be achieved, especially with carbon nanotubes (CNTs) [1,2]. Different dispersion techniques as well as curing conditions have influence on the formation of an electrically conductive network. Consequently material properties can vary and a gradient of electrical conductivity can be established in a large sample. If a mechanical load is applied to such a sample, the resulting changes in the conductive network structure will be reflected in a change of the overall sample resistance.

Experimental Study on Amine-Functionalized Carbon Nanotubes’ Effect on the Thermomechanical Properties of CNT/Epoxy Nano-composites
This paper investigated the effect of the amine-functionalized carbon nanotubes (CNTs) on the thermomechanical properties of CNT/epoxy nanocomposites. Mechanical stirring and ultra-sonication were utilized to uniformly disperse CNTs into the epoxy matrix. Non-functionalized and amine-functionalized CNTs with different weight percentages (wt. %) were mixed into the epoxy resin. Using standard te...
