Some documents about repair of cell phone jammer can be provided

Hong et al [39] studied by anthraquinone or naphthalene sulfonic acid treated polypyrrole, and add the appropriate amount of Ag nanoparticles, coated on the PET fabric surface, shielding performance of more than 30 dB, and a mechanism to shield the absorbing coating material mainly. Kim et al [40] in PET fabric intrinsic conductive polymer layer polymer (ICP), showed that PET / PPy composite fabric material shielding effect reaches 36 dB.We can solve the technical problems of    cell phone jammer   .  Yi Su and small [41] using single-arm carbon nanotubes as conductive filler, non-woven fabric of carbon nanotubes prepared by the arm thickness of 100 nm ~ 1 μm, materials, light weight and excellent performance and present the multi-walled carbon nanotubes (MWNT), there are many studies [42-43], the key technology is to prevent the agglomeration of MWNT, and MWNT surface covered set of modified technology, with powdered metal or conductive fibers together to achieve efficient electromagnetic shielding effect. This method is used for electromagnetic shielding film or composite shell material, fabric material is seldom used in the present, many research institutes at home and abroad kinds of composite nano-materials technology [44-45] electromagnetic radiation material. This type of    cell phone jammer    has the car charger. The use of advanced physical and chemical processes of metal ion treatment for which the shielding fabric prepared to absorb the main wave energy mainly through changes in the fabric of their own special features dissipated into heat, thus avoiding secondary pollution of the environment, clean air, its shielding low frequency, the frequency of electromagnetic radiation has a good effect, such a soft and comfortable fabric, color uniformity, strong anti-bacterial, washable, wearable and long life, and no skin irritation, skin microcirculation to help the human body.
Driven by a certain structure of the polymer insulation on the break area, so internal electrons are released, the formation of free movement of charge, so the fabric can have conductive surface, such absorbing fabric material is the subject of competing studies [36-37] Zn (1.90%), Sn (43.23%) fibers, In 30 ~ 1 000 MHz frequency range to 30 dB shielding effectiveness over the 6 layers of fabric material pressure of the shielding effectiveness of electromagnetic shielding to achieve 55 dB or more.Some documents about repair of    cell phone jammer can be provided.  China Technology Development Co., Ltd. Shanxi finery development of electromagnetic shielding fabric material, the stainless steel fibers evenly distributed in the cotton fibers, fabric at 10 GHz when the shielding performance to 34.77 dB [49]. As the carbon fiber material with good absorbing properties in recent years, many scholars at home and abroad for its blend with the general or individual textile fibers electromagnetic shielding fabric material obtained [50-51]. a Japanese institute a new process by deposition polymerization, obtained a layer of carbon fiber with graphite particles, the conductivity increased by 100 times, the materials and electromagnetic absorbing materials in the application has broad prospects.Fee caused by replacement of component of    cell  phone  jammer will be on your part.  2.5 multi-ion plasma shielding electromagnetic shielding fabric and more fabric material is the sixth generation of the most advanced shielding Lee et al [38] using a mixture of polypyrrole and AgPd metal or non-woven fabric coated on to get the shielding effect of the product in 8 ~ 80 dB, and with good absorbing properties, is a more promising absorbing textiles.
