Supported Copper Hydroxide Nanowires is developed for the technical preparation of supported Ultrafine Copper Powder development, contains copper hydroxide and carrier need to add copper products processing, the late compound without adding copper agent carrier. The characteristics of main components is copper hydroxide nanowires or nanosheets, characteristics of nano material with the macro effect, quantum tunneling effect and surface effect, shows high activity, bactericidal increase, lasting efficacy, strong adhesion, good suspension and so on. The introduction of nanotechnology can substantially improve the quality of copper preparations.
