摘要
MWCNT/water-based PU composites were synthesized by means of a colloidal-physics method. The effect of MWCNT addition on the electrical and thermal properties of the composites and the effect of NaCl addition on film formation of the PU latexes were investigated. The electrical conductivity of the water-based PU was improved by more than four orders of magnitude, but remained still four orders of magnitude lower than that of the MWCNTs. The percolation threshold was found to be at 0.5 wt.-% MWCNT. The thermal conductivity of the composites was improved by ≈86% at 7 wt.-% MWCNT. MWCNT/PU dispersions displayed stronger shear thinning than pure PU dispersions.
