Abstract: A method for making an impact-absorptive material is introduced. The method involves mixing silicon dioxide (SiO2) particles, polydimethylsiloxane (PDMS), and an appropriate amount of an additive, allowing the mixture to settle until tiny bubbles in the mixture are evenly distributed, thereby forming a colloidal solution raw material, adding a crosslinking agent to the colloidal solution raw material to form a colloidal solution plastic material, filling a die with the colloidal solution plastic material, heating the colloidal solution plastic material in the die such that it takes shape and forms an effective impact absorbing material, quickly and at low costs, for use in physical education, medicine, transportation, and safety-enhancing equipment.
