| titleOfInvention | Preparation and application of micro magnetic rod-shaped gel for measuring viscosity of trace liquid |
| abstract | The invention belongs to the technical field of material preparation, and particularly relates to preparation and application of a micro magnetic rod-shaped gel for measuring viscosity of trace liquid. The preparation method comprises the following steps: absorbing the aqueous solution prepared from the selected materials by using a PE capillary, and after orientation is carried out by a magnetic field, using a mode of ultraviolet light to initiate monomer polymerization to enable the solution to be gelatinized in the PE capillary; then the gel is taken out by a proper method and cut to obtain the micro magnetic rod-shaped gel required by the invention. The prepared micro magnetic rod-shaped gel has small size, the length is within a millimeter range, the diameter is 300 micrometers, the micro magnetic rod-shaped gel is driven to rotate by a uniform magnetic field, then the liquid viscosity is represented by utilizing the maximum rotating speed before different desynchronizing of the micro magnetic rod-shaped gel in liquids with different viscosities, the viscosity can be measured by only 1-2 ml of liquid to be measured, the operation is simple and convenient, the measurement is accurate, and the magnetic rod-shaped gel is prepared from polyacrylamide gel and magnetic nano particles, so the cost is low, and the mass preparation is easy. |
