Abstract

The invention discloses a polyethylene material. The surface of the polyethylene material is modified by rhodium complexes. The structural formula of the rhodium complexes is shown in formula (I) (please see the formula in the specification). The invention further discloses a preparation method and application of the polyethylene material. The surface of the polyethylene material is modified by the rhodium complexes through the recognizing effect of the rhodium complexes on calf thymus deoxyribonucleic acid, and the obtained polyethylene material has high antibacterial and anticancer capacity.

Description

technical field [0001] The invention relates to a polyethylene material modified by a rhodium complex, a preparation method and application thereof. More specifically, the present invention relates to a rhodium complex-modified polyethylene material obtained by using the rhodium complex to recognize calf thymus deoxyribonucleic acid, as well as its preparation method and application. Background technique [0002] With the development of science and technology, medical materials have played an increasingly important role. Polyethylene is widely used in the pharmaceutical industry as artificial blood vessels, catheters and other materials due to its non-toxic, chemical resistance and other advantages. However, the use of polyethylene as a medical material often faces problems such as lack of biocompatibility and bacterial invasion, leading to postoperative infection in patients. Recently, researchers have focused on improving polyethylene's antibacterial and other capabiliti...
