The effect of carbon nanoparticles on cellulosic handsheets

Abstract

Abstract This article describes the study of the effects of carbon nanoparticles on fibrous cellulosic webs. The handsheets were coated with coating colours containing graphene oxide (GO), carbon nanotube (CNT) and super conductive black carbon (SCBC) nanoparticles at different concentrations. The Raman method was used to assess the quality of the carbon materials and the changes in the band gap of the nanoparticles deposited on the handsheets. The influence of the type and content of the nanoparticles on the structural, mechanical, chemical and electrical properties of the composites was investigated and discussed. It was found that the range of failure modes and fracture surfaces seen in the SEM image is due to the influence of the different carbon materials as the main source of coating colour. The experimental percolation threshold curve and the total surface electrical resistivity of the samples were investigated. The SCBC coated samples exhibited low percolation threshold and comparatively high electrical conductivity at a certain maximum concentration. Each composite exhibited a pronounced stress distribution along the surface layer and the nanoparticle distribution was uniform. The surface resistance of the coated handsheets declined by about 14.103 times with the addition of only 1.0 wt% SCBC compared to the control sample. The composites coated with GO and SCBC nanoparticles at a concentration of 1.0 wt% had the highest tensile strength values.
