原始语种摘要: This work describes the flow behavior of prevulcanised natural rubber latex (PvNRL) and PvNRL nanoblends containing 0.02,0.04, 0.06, and 0.08 wt.% of aqueous dispersion of single-walled carbon nanotubes (SWCNT). The assay was performed undervarying shear rates (between 0.1-100 1/s) at three separate isothermal temperatures (25, 30, and 35 °C) on a Modular CompactRheometer (MCR) fitted with a concentric cylinder measuring system. A steady decrease in viscosity upon every single shearrate increment was observed for all the samples analysed. Thus, each measured viscosity was considered an apparent-viscosity;which confirms a typical non-Newtonian flow behavior. PvNRL blends containing highest wt.% SWCNT exhibited higher apparentviscosity at low shear rates, whereas the lowest wt.% SWCNT...
