Polymeric electromagnetic interference (EMI) shielding materials based on CO2 foaming technology have gained widespread attention due to their efficient use of CO2, high strength, corrosion resistance, and low cost. New design concepts and preparation techniques have led to the development of high-performance EMI shielding materials. This review summarizes the progress made in fabricating EMI shielding composite foams using supercritical carbon dioxide (scCO(2)) foaming and explores the relationship between component/distribution and EMI shielding properties. Additionally, it discusses the application prospects and development challenges of new EMI shielding composite foams.
As a critical action plan formulated for peaking carbon dioxide emissions, polymeric electromagnetic interference (EMI) shielding materials based on CO2 foaming technology have recently been attracting widespread attention in both research and industry, attributable to their efficient use of CO2, high specific strength, corrosion resistance and low-cost characteristics. In the past decade, the emergence of novel design concepts and preparation techniques for CO2 foaming technology has led to the development of new high-performance EMI shielding materials in this field. This review summarizes the research progress made to date on the fabrication of EMI shielding composite foams by supercritical carbon dioxide (scCO(2)) foaming. We also explore the structure-activity relationships between the component/distribution and EMI shielding properties. Additionally, the application prospects and development challenges of new EMI shielding composite foams are described.
