The invention discloses a surface super-capacitance modified material and a preparation method and application thereof. Specifically, the material with controllable super-capacitance characteristic is introduced into the surface of the material and charged, the charged material interacts with bacteria, interference on electron transfer of a bacterial respiratory chain is realized in a short time to inhibit growth and reproduction of the bacteria, the sterilization rate can be improved on the premise of not damaging the capacitance characteristic through cyclic charge and discharge, and the formation of a biological film is inhibited. The antibacterial system can quantitatively control the antibacterial process on the premise of not influencing the biocompatibility of the material, and has the advantages of environmental protection and controllability. |
