STUDY ON THE PROPERTIES OF SOLVENT-FREE MWNTs NANOFLUIDS/PP NANOCOMPOSITES

Abstract

Abstract: Ionic solvent-free multi-walled carbon nanotubes (MWNTs) nanofluids were obtained with the MWNTs as core, N,N-didecyl-N-methyl-N-(3-trimethoxysilylpropyl)ammonium chloride as corona and poly(ethylene glycol)4-nonylphenyl3-sulfopropyl ether potassium salt as canopy. And N,N-didecyl-N-methyl-N-(3-trimethoxysilylpropyl) ammonium chloride by ion exchange reaction. The structure and properties of nanofluids were studied by TEM, DSC, TGA and rheological testing. Solvent-free MWNTs nanofluids/PP nanocomposites were prepared through solution blending and mechanical blending. The effect of solvent-free MWNTs nanofluids on crystallinity of PP was studied. As a result, the MWNTs content is 23.67wt%. The solvent-free nanofluids have liquid-like behaviour. The solvent-free MWNTs nanofluids can improve the formation and number of crystal nucleus. The degree of crystallinity of the polypropylene matrix was improved a lot.

Key words: solvent-free nanofluids, multi-walled carbon nanotubes (MWNTs), polypropylene resin, liquid-like behaviour, nanocomposites
