Recently, many electronic devices have been used in our lives due to the development of electronic devices. Especially, most people are using smart phones in their daily life. However, the electromagnetic waves generated from smart phones have significant harmful effects on the human body such as nervous system abnormality, eye irritation. Due to these side effects, studies of electromagnetic wave shielding are being consistently carried out. In this study, electromagnetic shielding performance of the pressure sensitive adhesives(PSAs) with polyacrylonitrile(PAN)/pitch nanofibers was evaluated. The spinning solution was prepared by mixing solution of PAN dissolved in dimethylformamide(DMF) and solution of DMF insoluble pitch dissolved in DMF and tetrahydrofuran. The acrylic PSAs containing carbon nanofibers was coated on PET film and the electrical conductivity and electromagnetic interference shielding efficiency(EMI SE) were investigated. |
