Description

technical field [0001] The invention discloses a conductive polyolefin thermoplastic conductive special material for electroosmotic electrodes and a preparation method thereof, belonging to the technical field of electroosmotic motor materials. Background technique [0002] With the continuous growth of the population, the country's land resources are becoming more and more tense, and the treatment of swamps to achieve availability has become a solution. Electroosmosis is one of the electrokinetic phenomena. In the electric field, because the porous support absorbs the positive and negative ions in the water, the solution is relatively charged. Under the action of the electric field, the solution moves in a certain direction. This situation is called electroosmosis. It is negatively charged by adsorbing hydroxide ions, while the aqueous solution in contact with the paper is positively charged, causing the solution to move toward the negative electrode. When moving, it can c...
