Electromagnetic pollution refers to interference and harmful electromagnetic radiation caused by naturally and artificially generated electromagnetic waves. Along with the development of scientific and technical technologies such as broadcasting, television, microwave technology and the like and the development of electronic industry, as well as the rapid development of large-scale integrated circuits and the increasing popularization of electronic equipment, great convenience is brought to the life of people, but along with the pollution of electromagnetic radiation, the electromagnetic pollution gradually becomes another public nuisance in human life. It is reported that strong electromagnetic radiation can harm human health, interfere with the sensitivity of electronic instruments, affect the normal operation of sensitive electronic instruments, and even jeopardize their useful life. In addition, a large amount of electromagnetic radiation can be emitted during the operation of the machine, and a large amount of operation information can be carried in the electromagnetic radiation, so that the leakage of self confidential information is caused. With the development of electronic information war and electronic countermeasure in various countries, the attack to the other side by using high-intensity electromagnetic wave radiation also becomes a big means, but the engineering plastics as the shell of the electronic component has no shielding effect on the electromagnetic wave generated by the electronic product. Therefore, the electromagnetic shielding material is receiving more and more attention, and the electromagnetic shielding problem can be effectively solved by preparing the conductive polymer material and endowing the polymer composite material with conductive performance. The glass fiber is a commonly used reinforcing material in engineering plastics, and the conductive glass fiber prepared as the filler of the composite material can enable the composite material to have certain electromagnetic shielding performance, but still difficultly meets the increasingly high requirements of the electronic industry on the material, so that the deep research and development of resin-based composite materials with higher performance still is the development direction of electronic materials in the future.
Chinese patent application No. CN00802324.7 discloses an electromagnetic shielding plate with high shielding effect. The electromagnetic shield plate is formed of a flat plate having elastic conductivity, and has a bent connection piece and a support portion at the edge of the electromagnetic shield plate, the bent connection piece and the support portion having a tip end side protruding from the plate surface. When the electromagnetic shield plate is combined with the printed circuit board, the grounding structure of the printed circuit board is reliably contacted with the connecting sheet, thereby achieving high shielding effect.
Chinese patent publication No. CN102065672B discloses a method for manufacturing electromagnetic shielding plates by effectively recycling tetra pak waste, which comprises pulverizing tetra pak waste to obtain a mixture of paper/plastic/aluminum fibers; spreading paper/plastic/aluminum fiber mixture as base material and metal fiber with diameter of 30-60 μm and length of 3-10mm as filling material to form green compact; at least one metal fiber layer is paved in the pressed compact; the application amount of the metal fibers in the green compact per square meter is 92-125 g; and pressing the pressed compact into a plate. The method is simple and feasible, convenient to implement and low in cost, and the plate has excellent shielding efficiency and good physical and mechanical properties.
Chinese patent publication No. CN1384703 discloses an electromagnetic shielding plate having a glass substrate and a geometric pattern formed on the substrate, wherein the geometric pattern comprises an inorganic filler selected from the group consisting of metals and metal oxides, and a glass component having a softening point of about 200-.
As shown in the above three patents, they all disclose related art products in the art, but there are few mentions about high performance resin-based composite materials having electromagnetic shielding properties. Therefore, the resin-based composite material substrate which has a more stable structure, better physical and mechanical properties and better electromagnetic shielding properties is urgently needed to be developed.
