Abstract:

 In this study, the traditional mixed oxides method was used to create kaolinite-PVA composites. The single phase kaolinite compound with the chemical equation Al2Si2O5OH4 was generated after sintering at 1150C for 4 h. For the structural investigation, various quantities of kaolinitePVA were generated. X-ray diffraction XRD was carried out for the structural analysis, which indicated that second phase did not form in Al2Si2O5OH4. In addition, by using Al2Si2O5OH4PVA compositions and epoxy powder in various proportions, microwave shielding effectiveness composites were manufactured by hot pressing method. Utilizing a network analyser device, the microwave shielding effect of Al2Si2O5OH4PVA composites were investigated in the range of 6-18 GHz. A minimum shielding effect value of -47.02 dB was obtained at 6.92 GHz at 1.4 mm thickness. The Al2Si2O5OH4-PVA compounds were produced as composite material and their properties were characterized for shielding effect. To work in higher and required frequency bands, by adjusting the amount of components in the composites, the performance of the microwave shielding effect can be changed.

 Bu çalışmada, kaolinit-PVA kompozitlerini oluşturmak için geleneksel oksitlerin karışımı yöntemi kullanılmıştır. Al2Si2O5OH4 kimyasal denklemine sahip tek fazlı kaolinit bileşiği, 1150Cde 4 saat sinterlendikten sonra elde edildi. Yapısal araştırma için çeşitli miktarlarda kaolinit-PVA üretildi. Yapısal analiz için X-ışını kırınımı XRD yapıldı, bu da Al2Si2O5OH4te ikincil fazın oluşmadığını gösterdi. Ayrıca çeşitli oranlarda Al2Si2O5OH4-PVA bileşimleri ve epoksi tozu kullanılarak mikrodalga kalkanlama etkili kompozitler sıcak presleme yöntemiyle üretilmiştir. Bir ağ analizör cihazı kullanılarak, Al2Si2O5OH4PVA kompozitlerinin mikrodalga ekranlama etkisi 6-18 GHz aralığında incelenmiştir. 1.4 mm kalınlıkta 6.92 GHzde minimum -47.02 dB ekranlama etkisi değeri elde edilmiştir. Al2Si2O5OH4PVA bileşikleri kompozit malzeme olarak üretilmiş ve kalkanlama etkisi için özellikleri karakterize edilmiştir. Daha yüksek ve gerekli frekans bantlarında çalışmak için, kompozitlerdeki bileşenlerin miktarı ayarlanarak, mikrodalga kalkanlama etkisi performansı değiştirilebilir.
