Electromagnetic waves of transmission lines or various electronic devices interfere with each other and cause malfunction or damage of electronic devices. It is called Electromagnetic interference (EMI). Because conductive materials reflect electromagnetic waves, metal or carbon nanomaterials are used for EMI shielding. Polyimides have excellent characteristics such as electric insulation, heat resistance and chemical resistance. Based on these properties, they have been used in display, aircraft and engineering materials. Especially, they have been widely used as electric insulating tape or electric insulating coating using electric insulation properties. In this study, PI/EGaIn/PI sandwich films were prepared from 4,4′-(hexafluoroisopropylidene)diphthalic anhydride (6FDA), 2,2'-bis(trifluoromethyl)benzidine (TFMB), polydimethylsiloxane (PDMS) and EGaIn dispersion in MeOH. We studied films properties including EMI shielding effect, heat resistance, and flexibility. |
