(Summary description)The influence of low-temperature plasma generator on the electrical conductivity and biocompatibility of materials: Polymers usually have good material properties, but due to their own material reasons, hydrophilicity, adhesion, conductivity and biocompatibility may be poor. Plasma treatment of the material can maintain the excellent performance of the material itself. At the same time, the above-mentioned performance has also been significantly improved. The following focuses on the application of low-temperature plasma generators in material conductivity and biocompatibility. The improvement of the conductivity of the surface of the polymer material by the low-temperature plasma generator: Improving the conductivity of polymer materials is one of the application directions of plasma. Through the graft polymerization treatment of low-temperature plasma generators, PET conductive films with better conductivity can be prepared. Plasma induced grafting technology can also be used to prepare conductive films on the surface of the material. Polymer improves its antistatic performance and improves product utilization. The effect of low-temperature plasma generator on the biocompatibility of materials: When polymer materials are used in the biomedical field, in addition to strength and elasticity requirements, they should also meet biocompatibility standards. The impact on the biocompatibility of materials can be understood from the following aspects. 1. Using a low-temperature plasma generator to treat the surface of HPPA can produce —NH2 groups on the sodium polyhydroxyphosphate HPPA, so that the biological activity of HPPA can be fully exerted. 2. Using argon plasma and oxygen plasma to process polymethyl methacrylate can improve the wettability of the material surface and increase the adsorption capacity. 3. Avoid non-specific protein adsorption on the surface of the material, and keep the surface of the material clean for a long time. It is often used in contact lenses, wound healing materials, urinary catheters, biosensors, etc. 4. Treating the PET film can prolong the retention time of albumin after adsorption and improve the anticoagulant property. 5. The low-temperature plasma generator is used to improve the positioning and fixation of bone and artificial joints, and improve the wear resistance and biocompatibility of joint joints. I believe that with the continuous development and application of science and technology, the application of low-temperature plasma generator plasma surface treatment technology can not only improve the performance of polymer materials in special environments, but also indirectly expand the application range of polymer materials, so that Its application range in processing polymer materials, especially in biomedical materials, is continuously expanding.
