After years of hard work, authoritative experts, scholars and professionals from all over the world conducted a lot of research on the surface modification of carbon fiber materials. The key research focuses on improving the surface roughness and surface organic chemical group of fiber materials. Carbon fiber material treatment methods include surface oxidation treatment, surface coating treatment, high -energy radiation sources, plasma technology, etc.

Among them, the electrochemical oxidation method has the characteristics of sustainable production and easy control, and has been applied to the industrial field. However, it still needs a large amount of chemicals, which consumes great power and causes a large amount of sewage and residues. For white mold carbon fiber materials, the treatment time must be increased due to difficulty oxidation of air. Different from chemical solvents, plasma has the advantages of cleaning, environmental protection, time saving time, energy and efficiency, and is a very promising engineering application method.

The principle includes two levels: on the one hand, the surface of the fiber material generates oxygen free radicals and positive and negative official groups to improve surface energy and hydrophilicity; on the other hand, improve the surface roughness of fiber materials and remove surface pollutants of fibrous materials.

Plasma technology is used for the surface modification of carbon fiber materials in the solution, the interaction of active particles and water in plasma technology, remove the surface mortar of carbon fiber materials, and complete the hydrophilicity of carbon fiber materials.

Carbon fiber materials, as a key fiber material, are used in national defense safety and defense industries such as aerospace, weapons, as well as high -tech industries such as transportation and biomedical engineering. Quality performance. Carbon fiber material is a micro -crystal graphite raw material along the fiber material, such as block -shaped high -pure graphite nano crystals. Its surface is a non -polar high -crystal high -pure graphite structure, with high organic chemistry and plasticity, which leads to poor surface performance. The comprehensive performance of the composite material after endangers the application of carbon fiber materials under unique working conditions.

At this stage, the surface modification of carbon fiber materials has become an indispensable key process for the manufacturing of carbon fiber materials. Carbon fiber material manufacturers use the actual effects of surface modification as the main factor in evaluating the quality of carbon fiber materials. Generally speaking, the cleaning surface modification of the plasma fiber material is very important for the manufacturing and use of carbon fiber materials.
