Description

Technical field [0001] The invention belongs to the technical field of conductive polymer materials, and specifically relates to a conductive polymer-graphene nanocomposite material, a preparation method thereof, and use in waste recycling treatment. Background technique [0002] Many wastes are rich in precious metals and rare metals such as gold, silver, palladium and platinum. For example, the grade of metals contained in electronic waste, especially waste printed circuit boards, is dozens of times that of ordinary primary ore. Therefore, the recycling of metal resources in waste has become a sunrise industry in the metal recycling industry at home and abroad. [0003] At present, the most widely used method for recycling metal resources in waste is a combination of physical and chemical methods, and the chemical method mostly uses hydrometallurgical technology. Specifically, the crushed waste fragments are leached in an acid or alkaline liquid, and the leachate is subjected to...
