Electromagnetic (EM) radiation pollution is becoming more and more serious with increasing use of electrical and electronic devices in our daily lives.
In modern automobiles, the growing quantity of onboard electronics and microprocessor-controlled systems requires that the electronic sub-assemblies (ESA) in the vehicle meet EMC requirements. Metal, in the form of thin sheets or sheathing, is an effective EMI shielding material common in automotive applications. Recently, conductive polymer nano-composites have attracted a great deal of academic and industrial interest due to their potential applications in many areas including EMI shielding. YTCA is currently engaged in research and development of EMI shielding materials for automotive and other applications. YTCA is also studying the use of large-scale polymer processing techniques, for producing practical EMI shielding products from conductive polymer nanocomposites.
In new work, scientists in Korea have now demonstrated that single-layer graphene is an excellent choice of material for high-performance EMI shielding.
There have been experimental reports and theoretical analysis about the shielding effectiveness of graphene.
Schematic drawings of the measurement setup for the electromagnetic interference shielding effectiveness of graphene. For accurate assessment of the EMI shielding capability of a graphene layer, the researchers needed a true monolayer graphene over the entire area of the shield. So far there have been no theoretical studies on the mechanism of EMI shielding of graphene. Since graphene has negligible mass and is ultrathin, transparent, and flexible, it will be an excellent choice of EMI shielding material for portable electronic devices, transparent electronics, automobiles, and EMI isolation of 3D integrated circuits, etc. We are very satifised with your product and service,we will cooperate with you for more order. Telephone, air-conditioning, fire-fight devices, optical fiber and CAT5 cables can be equipped customized.
Decoration will be arranged in the shielding room according to standard equipment room requirements.

One piece shielding, shielding with peel away tops or two piece shields consisting of a a€?fence and covera€? combination are typical designs for shielding. Mutual interference among devices such as TVs, computers, mobile phones, and radios can degrade device performance. If airbag, cruise control, anti-lock braking, or other electronically controlled assemblies are adversely affected by EMI, operation of the vehicle or its critical safety systems could be compromised. However, metal is expensive, heavy, and prone to corrosion, while adding to the complexity and cost of manufacturing processes. In contrast to larger conventional composite fillers, nano-composite fillers have at least one dimension in the nanometer range, including materials such as carbon nanotubes (CNT) and graphite nanoplatelets (GNP). One research focus is to optimize dispersion of conductive nano-fillers in the matrix of polymers such as polypropylene (PP).
Unlike the research work on filler dispersion optimization, few organizations have addressed the mass-production issue. They found that CVD-synthesized graphene shows more than seven times greater EMI shielding effectiveness (in terms of dB) than gold film of the same thickness. But in these previous works, the researchers used graphene flakes obtained by the reduction of graphene oxide, not a single layer graphene as in this work. With the new model developed by the KAIST team, researchers can now predict the EMI shielding effectiveness of graphene for a specific application.

Have you just published a scientific paper or have other exciting developments to share with the nanotechnology community? They are jointed in way and welded with CO2 protection, which can restrain the plates from distortion and ensure the leveling of the steel plates.

As mandated by safety and reliability requirements, the automotive onboard ESAs must not emit EMI signals, and must be immune to external EMI signals. Conductive polymer composites offer a potentially cost-effective and process-friendly alternative to metal. These high-aspect ratio nano-scale fillers form conductive networks much more readily than conventional conductive fillers. Because of the strong tendency of nanoparticles to agglomerate, uniform dispersion of conductive nano-fillers in the polymer matrix is a considerable challenge. Promising composite formulation and process techniques are being identified and will then be tested on pre-pilot-production scale.
This finding is significant because it means that graphene is the most effective material for EMI shielding in terms of shielding effectiveness per mass.
Shields can be etched as flat pieces with or without etched bend lines to ease forming at your facility or we can form at our in-house forming department. One example depicted below is the EMI shielding film attached to the filter of a plasma television display panel. Conventional conductive fillers such as metal flakes, stainless steel fibers, or carbon fibers are dispersed in a polymer matrix creating an electrically conductive network that acts like a Faraday cage.
Due to larger filler-matrix interface, mechanical and thermal properties may also be enhanced or improved.
Yet, this is essential to the formation of an effective conductive network at low filler loading. Part numbers, logos or other identification can be included on your shields as well, further developing the shielding to your requirements. Advancements have been achieved in this area through the use of a proprietary compounding technique.
