Abstract: The present invention provides a method for preparing an antibacterial and low-adhesion cross-linked polyvinyl alcohol coating. A simple two-step method is adopted, wherein polyfunctional isocyanate is first used to strongly cross-link with the hydroxyl group of polyvinyl alcohol, and then a compound with low surface energy such as mono-hydroxyl silicone oil or the like is received in to effectively reduce the surface energy of the surface of the coating; and two structure-function relationships are efficiently synergistic through effective strong cross-linking and regulation of the compound with low surface energy within the system, enabling the strongly cross-linked polyethylene coating to have excellent performance of water adhesion resistance and oil adhesion resistance, and good performance of bacterial adhesion resistance, which is expected to be applied in the fields of materials for antifouling and self-cleaning, liquid transportation and implantation in animal body.

Abstract: A drawing faucet includes a drawing sensing structure. The drawing sensing structure includes sense marks and a sensor. The number of the sense marks is at least two, they are provided on the drawing hose at intervals along a length direction of the drawing hose. The sensor is configured to sense the movements of the sense marks. During a drawing process of the drawing hose, at least the sense marks at two ends along the length direction can follow the movement of the drawing hose and be sensed by the sensor. The automatic water discharge control unit correspondingly controls the water discharge to change the water discharge strategy according to the sensing signal of the sensor.
