Experimental and theoretical investigations of the rheological and electrical behavior of nanocomposites with universal percolation networks

Electrically conductive ceramic/polymer nanocomposites with universal percolation networks and varying contents of nanoparticles were prepared herein; the effects dispersed state on electrical conductivity investigated. The by coating carbon black (CB) a silane coupling agent, followed their subsequent dispersion in 1,6-hexanediol diacrylate (HDDA) photocurable polymer. physical properties nanocomposites, such as viscosity, photocurability, flowability, dispersibility, investigated respect to loaded CB content. A correlation between internal dispersibility was established conducting theoretical analysis based conditions particle dispersion, aspect ratio, orientation, interface. comparison experimental values theoretically obtained results assisted identifying nanoparticle network structure polymer matrix imperfect/tunneling interfaces threshold (c*) 0.016. conductivity, heat deflection temperature (HDT), tensile strength 3D-printed nanocomposite products analyzed; scanning electron microscopy (SEM) also employed examine these samples. This study suggests new development strategy for improving quality nano-products quantitative materials.
