Description

Technical field [0001] The invention involves the field of electronic technology, especially an electromagnetic shielding conductive coating and its preparation methods. Background technique [0002] Coatings are painted in Chinese traditional names.The so -called coating is the surface of the protected or decorated object, and can form a continuous film that is firmly attached with the coating. It is usually based on resin, oil, or lotion.Corresponding additives, viscous liquids made of organic solvents or water.The book "Coatings Craft", which is more authoritative in the Chinese coating industry, is defined as this: "Coating is a material, which can be coated on the object surface with different construction processes to form a strong adhesion, a certain strength, continuous continuous, continuousSolid -state film. The formation of this formation is called coating film, also known as paint film or coating. " [0003] Paint, what we usually call paint is just one of them.Finger...
