| description | Disclosed are an ultrahigh-concentration shear thickening fluid, a preparation method therefor, and a use thereof. The fluid is composed of nanoparticles and a solvent, the volume fraction of the nanoparticles in the fluid is 0.63-0.65, and the solvent is liquid polyhydric alcohol. The nanoparticles are pre-mixed and then are subjected to strong shear dispersion until a "Tyndall effect" appears, then a high-circulation instrument is used for further mixing uniformly such that the fluid has good uniformity, and finally drying is performed until the total content of small molecule alcohol impurities is not more than 3.5 wt%. The shear thickening fluid of the present invention has a concentration of 0.63-0.65, has a greater thickening amplitude (the ratio of the highest concentration to the lowest concentration is more than 1000 times at most) than that of discontinuous shear thickening of all existing fluids, has a better impact energy absorption effect, and has more significant improvement on the impact resist |
