Shear thickening refers to that the viscosity occurred when the shear stress (strain) suffered by material increases time increases, " solidification " behavior that material changes software strategy into software-hardware strategy. Shearing retrogradation phenomenon and be found in particle suspension system the earliest, such as mud, starch dispersion liquid etc., system includes disperse medium such as viscous liquid and dispersion such as micro-nano granule, all has been found that shear thickening phenomenon in present solid composite material and gel rubber material. Over nearly 20 years, shear thickening phenomenon is by extensive concern, and existing multiple dispersed particle and disperse medium collocation thereof constitute the suspension with shear thickening phenomenon, and typical particle includes inorganic particulate such as SiO2、CaCO3、Fe2O3, glass fibre etc., organic filler such as starch, compound particle include polymethyl methacrylate (PMMA) microsphere, polystyrene (PS) microsphere, polystyrene graft acrylic acid (PS-g-AA) microsphere, poly dimethyl propionic acid amide .-acrylic acid (P(DMAA-AA)) microsphere etc., disperse medium includes water, Polyethylene Glycol, glycerol, different chain length aliphatic hydrocarbon etc. When microgranule reaches certain volume mark in suspension system, there is shear thickening phenomenon immediately.
If can introduce in packaging film by the shear thickening phenomenon of this mystery, the packaging film being presents soft feature in normal state, and when being subject to severe impact energy-absorbing realize protection, packaging film will be made undoubtedly to have broader practice space.
