Abstract: Recently, electromagnetic radiation pollution has become one of the problems that people pay attention to. In this paper, natural graphite and carbon nanotubes were used to produce wood plastics composites with electromagnetic shielding performance through a molding method. Flexural properties, electrical resistivity and electromagnetic shielding properties were studied using a material testing machines and EMI apparatus. The results showed that graphite and CNTs show a good synergistic effect. Flexural strength increased from 55 to 62 MPa and flexural modulus was elevated from 6380MPa to 7129MPa. The water absorption of composites increased as CNTs increased, whereas electrical resistivity decreased. The electromagnetic interference shielding effectiveness (EMI SE) increased as CNTs increased. By and large, the experimental results of EMI were equal to that of theoretical calculation. EMI SE of composite increased from 16 to 35dB due to the addition of CNTs, and these results could meet the requirement of commerce.Abstract: Recently, electromagnetic radiation pollution has become one of the problems that people pay attention to.

Abstract: In recent years, germanium containing sulfur compounds have attracted much attention due to their complex structural properties and potential applications, and have been widely used in nonlinear optics, molecular sieve, ion exchange and so on. Group 11 elements Ag have been proved to be successful multifunctional elements often used for synthesis, because they have rich coordination modes and electrothermal properties. In addition, they also enhance the metalophilic interaction, overcome the repulsive force between cationic metal centers, and more easily enter the skeleton to form new materials with unique topological structures. The potential applications of these materials extend beyond traditional fields. The synthesis and structure of germanium chalcogenides containing transition metal silver are reviewed in this paper. Various coordination modes of structural units in the basic framework of transition metal silver and germanium sulfide compounds, synthesis methods, structural characteristics and applications of different germanium sulfide compounds containing transition metal silver are summarized. And the synthesis of germanium sulfide compounds containing silver when alkali metals, transition metal complexes, organic amines are used as structure guide agent.Abstract: In recent years, germanium containing sulfur compounds have attracted much attention due to their complex structural properties and potential applications, and have been widely used in nonlinear optics, molecular sieve, ion exchange and so on.
