    Silica Suspensions: Discontinuous Shear Thickening, Shear Jamming, and Shock Absorbance'

## Description

- description: Concentrated particle suspensions exhibit rheological behaviors, such
    as discontinuous shear thickening (DST) and dynamic shear jamming (SJ), which
    affect applications such as soft armors. Although the origin of these behaviors
    in shear-activated particle–particle contacts has been identified, the effect
    of structural and chemical properties, especially the role of liquids, on these
    behaviors remains unexplored. Hydrogen bonding in suspensions has been proposed
    to be essential for particle friction, and therefore, few studies on DST and SJ
    have focused on non-aqueous suspensions, mainly on liquid media with a hydrogen
    bonding ability. To identify an alternative mechanism, this study explored the
    effects of liquid polarity on the rheological behaviors of silica particle suspensions.
    Owing to their excellent particle dispersion, the DST behaviors of polar liquids
    were observed, independent of protic and aprotic liquids. In contrast, nonpolar
    liquids formed particle agglomerates because of the particle–particle attraction
    and became a paste at a high particle fraction. The SJ behavior was confirmed
    for three aprotic liquids (propylene carbonate, 1,3-dimethyl-2-imidazolidinone,
    and N,N-dimethylpropyleneurea), indicating that, besides hydrogen bonding, liquid
    polarity is another important parameter for silica particle suspensions. The diverse
    mechanisms of shear-activated particle–particle friction present material design
    possibilities for the rheological properties of concentrated particle suspensions.
