A novel application of nanotechnology in the field of mechanical engineering, called colloidal damper, is investigated. This device is complementary to the hydraulic damper, having a cylinder-piston construction, but the hydraulic oil is replaced by a colloidal suspension, consisted of a mesoporous matrix and a lyophobic liquid. Here the porous matrix is composed from hydrophobized silica gel and water is considered as associated liquid. The colloidal damper test rig has only one room inside of the cylinder, but due to the pre-pressure applied, it is able to dissipate energy for both positive and negative displacement of the piston. Variation of the damper's dissipated energy and efficiency versus working parameters (frequency, displacement, pressure, pre-pressure) is illustrated.
