Description

technical field [0001] The invention belongs to the technical field of new polymer materials, and in particular relates to a polymer composite material which can be used for impact protection and a preparation method thereof. Background technique [0002] In recent years, impact protection materials have received extensive attention due to their high application value. At present, commercial impact protection materials are mainly shear thickening materials, which increase the stress area through hardening under impact to reduce impact damage. However, the creep resistance of shear thickening materials is poor, and other creep-resistant polymer materials need to be compounded. Moreover, the impact protection mechanism of the shear thickening material is single, and the protection performance is still insufficient. Contents of the invention [0003] In view of this, in order to develop a polymer composite material with a new type of impact protection mechanism, excellent i...
