The research for electromagnetic shielding function of paper
Abstract: With technological advances, electronic products universal thousands of households, the number of high-power electrical equipment increased dramatically, leading to a sharp deterioration of the electromagnetic environment, resulting in a series of dangerous problems. Carbon fiber and plastic, resin matrix after the formation of resin-based composite fiber-reinforced composite materials, advanced composite materials in modern representative of the typical, but also a function of electromagnetic shielding materials.
This paper described the principle of electromagnetic shielding and the performance of carbon fiber through the different concentrations, different dispersing agent, as well as different methods of surface modification on dispersion of carbon fibers to explore the impact study of carbon fiber in the aqueous dispersion of the performance of carbon fiber paper conductivity function and electromagnetic shielding properties. The results showed that with the continuous carbon fiber content increased, the overall performance of electromagnetic shielding in continuous improvement was elected as the use of Polyacrylamide dispersant, the dispersion properties. Titanate coupling agent, through the modification of the modified carbon fiber, its dispersion properties, conductivity and electromagnetic shielding properties are improved.
Through the study of the subject to prove that the electromagnetic shielding of carbon fiber of the feasibility of paper, for the early development of high performance electromagnetic shielding paper lay a theoretical foundation, it provides the data basis.
