▎ 摘　　要

NOVELTY - Preparation method of dispersed phase particles, involves (A) dispersing graphene oxide in the solution proportionally and breaking under ultrasonic conditions, (B) adding nano oxide particles and stirring under the condition of blocking light and until a uniformly mixed dispersion is obtained, (C) adding dopamine hydrochloride to the mixed dispersion obtained in step (2), adjusting the pH to 8.5-9.5 with aqueous ammonia, fully stirring for at least 10 hours under the condition of blocking light, placing graphene oxide, adding nano-oxide particles and dopamine hydrochloride and (D) completely mixing graphene oxide, nano oxide particles and dopamine hydrochloride, centrifuging and washing with water. USE - Preparation method of dispersed phase particles for shear thickening fluid. ADVANTAGE - The dispersed phase particles use the adhesiveness of polydopamine to wrap the nanoparticles, thus enhancing the connection between the graphene oxide sheet layer and the nanoparticles. The polydopamine in the shear thickening fluid indirectly adsorbs other molecules through the coordination of metal ions, which is conducive to the formation of the shear thickening fluid and improves the performance of the shear thickening fluid. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) dispersed phase particles, which comprise graphene oxide, nano-oxide and polydopamine. The polydopamine is connected to the graphene oxide through a polar group and the nano-oxide is adsorbed on the sheet structure of the graphene oxide or is encapsulated by polydopamine; and (2) method of applying the dispersed phase particles for the shear thickening fluid to strengthen the fibrous material, which involves dispersing the dispersed phase particles in an organic solution to obtain a shear thickening fluid, diluting with absolute ethanol, immersing the fiber fabric in the diluent, taking out the fiber fabric and drying.
