Synthesis and characterization of structural and magnetic properties of graphene/hard ferrite nanocomposites as microwave-absorbing material

Pengaruh Penambahan Aditif Bi2O3 Terhadap Karakteristik Barium Heksaferit Hasil Sintesis dengan Metode Sol-Gel

“…Dengan kelebihan tersebut barium heksaferit sangat banyak digunakan di berbagai bidang industri, seperti media perekaman magnetik (Onayagi et al 2016), aplikasi microwave (Durmus, Durmus, dan Kavas 2015) dan sebagai Multi-Layer Ionization Chamber (MLIC) yang merupakan komponen penting dari camcordes, pager dan notebook computer (Iqbal, Mir, dan Alam 2010) Barium heksaferit berukuran nano sangat diperlukan dalam aplikasi perekaman maupun microwave absorber. Bahan dengan ukuran nano mempunyai luas permukaan tinggi, sehingga akan mengurangi jumlah pemakaian materi tersebut dan akan menghasilkan produk yang lebih tipis yang merupakan tuntutan perkembangan teknologi dewasa ini.…”

Quantifying structural and electromagnetic interference (EMI) shielding properties of thermoplastic polyurethane–carbon nanofiber/magnetite nanocomposites

“…Soft and hard ferrites are the most extensively studied magnetic materials for the electromagnetic interference (EMI) shielding, specifically microwave or radar absorbing, applications [1][2][3][4][5][6][7][8]. The unique structural and physical features of single or mixed-structure ferrites make them proper materials for absorbing of electromagnetic waves in the relatively high-frequency region (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) which is an important range for radar absorbing and military applications. In recent years, combination of magnetic materials with both various forms of carbon materials such as carbon fiber, carbon nanotubes (CNTs), graphite and graphene derivatives, and carbon nanofiber (CNF) and also with different polymers by regarding the composite approaches have been studied to improve the shielding efficiency (SE) and extend the processability and applications of such materials [9][10][11][12][13][14].…”
