Zusammenfassung: | The invention discloses a hydrogel surface Zeta potential testing device and a working method thereof, and belongs to the technical field of functional polymer material performance testing. Comprising a fixed bracket, a high-position container, a low-position container, a sample storage device, a pressure difference detection device, a digital source meter and a circulating pump, the high-position container is mounted on the fixed bracket; the circulating pump is arranged in the low-position container; an electrolyte solution is contained in the high-position container and the low-position container; the height of the sample storage device is between that of the high-position container and that of the low-position container; a sample to be detected is placed in the sample storage device, and an electrolyte solution circularly flows among the high-position container, the low-position container and the sample storage device. The device is reasonable in structural design, low in cost and simple to operate, a rel |
