(Summary description)Changes of surface activity of nylon dental materials treated with plasma surface processor: With the continuous improvement of nylon processing technology and modification technology, the application scope of plasma surface treatment has expanded rapidly, and the application requirements of nylon surface cleaning, material protection, enhancing adhesion or dyeing are increasing. However, the structure of various nylon materials is different, and the corresponding surface properties are also very different. In order to adapt to various applications, plasma surface treatment technology came into being. Titanium is an inert metal material with low biological activity and is easily wrapped in a fibrous membrane after implantation in the jawbone. The lack of initiative results in long osseointegration times, poor initial stability, and low long-term success rates. However, pure titanium has low hardness, poor fatigue strength and wear resistance. During the use of titanium implants, failures such as loosening of abutment screws, pitting corrosion, wear and corrosion of connecting threads occur, which seriously affect the reliability and service life of the implant system. . Plasma surface treatment provides adhesion to nylon surfaces and improves surface hydrophilicity and wettability by introducing polar organic functional groups to the surface. Clean surface and surface wettability play an important role in the color combination of the two surfaces. Surface wetness depends on the surface condition of the nylon itself and all nylon dyed materials. The surface tension of these dyed materials can be reached to the required value by efficient treatment with low temperature plasma. After the plasma equipment was treated and modified, the water droplets of the contact angle tester slipped down from the top of the implant, and the angle value could not be determined and was close to 0. Existing experiments have proved that under the corresponding process gas and other conditions, the super-hydrophilic change on the surface of dental implant titanium implants by plasma treatment has important medical significance. Before processing: the contact angle of the nylon tube is 78.16°; After the plasma cleaning machine, the contact angle of the nylon tube is close to 0°; Result: Plasma treatment by plasma surface processor can significantly change the surface activity of nylon material, and can significantly improve its surface energy and hydrophilicity, and enhance the dyeing ability. Due to the unique physical and chemical properties of the surface material and its successful application in finishing, lubrication, bonding, foaming, waterproofing and biomedical materials, its wetting performance is one of the important properties of the surface material, which mainly depends on Microgeometry and chemical composition of surface materials. The adsorption and proliferation experiments of osteoblasts were carried out using a plasma surface processor, and the results showed that their surface oxidation activity was better than that of heat treatment. The superhydrophobic surface was prepared by the method of molecular self-assembly, and the contact angle can reach more than 130 degrees. The conversion and control of sample superhydrophilicity and superhydrophobicity can be realized by plasma treatment with a plasma surface processor.
