Abstract

The shear-thickening phenomenon behavior occurs in most of the concentrated colloidal dispersions such as clay–water, calcium carbonate–water, polystyrene–silicon oil, iron particles–carbon tetrachloride, titanium oxide–resin, silica–polypropylene glycol, and silica–polyethylene glycol have attracted the attention of protective systems development applications. The rheological properties of Shear Thickening Fluids (STF) can be controlled by the composition of the carrier fluid molecular weight with chain length and solid particles influence a few parameters, such as particle size, volume fraction, and critical shear rate range. The methodology used in this study, numerous material parameters impacting shear thickening behaviour and the usage of STFs in protective systems are examined, with a focus on the nature of solid phase nanoparticles. This analysis includes investigations of important parameters, such as particle size and volume fraction, majorly influencing the Shear Thickening Fluid (STF).
