This is caused the electromagnetic interference problem producing by electrical products and seriously increasing. Not only influence each other of electrical products but also may damage people's health. So, how to decrease problem of electromagnetic interference is a major issue in recent studies.
In this study, the nano Fe3O4, nickel coated glass (Ni/Glass), and carbonyl iron wire are used to fills in epoxy or nickel foam to study the effects of the electromagnetic shield. The different weight percentages of magnetic powders are prepared and hybrids with nickel foam composites are conduct to examine the EMI shielding effectiveness (SE).
This study indicates the sequence of SE effects for these materials is Ni/Glass>iron wire>Fe3O4. The EMI shielding effectiveness of hybrid composites is greater than that of pure composite structure.
