چکیده انگلیسی
A novel composite with excellent sensing property and safeguarding performance is fabricated by impregnating the carbon black (CB)/shear thickening gel (STG) hybrid into polyurethane sponge (PUS). This STG-CB/PUS composite presents typical shear thickening characteristic, as the storage modulus (Gâ²) rises from 0.21â¯MPa to 1.52â¯MPa when shear frequency increases from 0.1â¯Hz to 100â¯Hz. Under external strain, the conductivity of STG-CB/PUS varies quickly, thus it can be applied as strain sensors. During the impact, STG-CB/PUS can detect impact stimuli (0.147-1450â¯mJ) and decrease attacking force by 63% simultaneously. Additionally, it is found that the 'BO cross bond' is responded for the shear thickening property and the structure-dependent electrical behaviors contribute to the sensing activity. Finally, a STG-CB/PUS enhanced kneepad is prepared. It possesses a reliable safeguarding performance by reducing 44% attacking force and can effectively trace human body motions such as walking, running and jumping.
