Description

technical field [0001] The invention belongs to the technical field of medical materials, in particular to a medical antibacterial polymer material and a preparation method thereof. Background technique [0002] With the development of medicine, medical polymer materials have been widely used in the medical field. According to different medical purposes, some medical polymer materials need to be in contact with human skin, some need to be in contact with body fluids, some need to be in contact with blood, some need to be implanted in the human body for a short period of time, and some even need to be implanted in the human body for a long time. Therefore, in addition to good processing properties and physical and mechanical properties, such materials must also have excellent biocompatibility. However, during use, the surface of the material is prone to colonization and reproduction of microorganisms, thereby causing infection. Contents of the invention [0003] The objec...
