Abstract Sampel penebat telah dihasilkan melalui campuran nisbah 50:50 PP/EPDM tanpa/bersama-sama 5wt% kepekatan zarah Al2O3, TiO2, BN and Organoclay yang bersaiz nano. Nilai pemalar dielektrik diperolehi adalah dengan menggunakan Penganalisis Bahan. Keputusan menunjukkan nilai pemalar dielektrik pada campuran PP/EPDM adalah rendah berbanding dengan campuran PP/EPDM/Al2O3, PP/EPDM/TiO2 dan PP/EPDM/BN. Hasil campuran PP/EPDM/ bersama-sama zarah Organoclay bersaiz nano menunjukkan nilai pemalar dielektrik mengalami sedikit penurunan. Selain itu, hasil daripada keputusan voltan pecahan dan simulasi Opera-2D akan dinilai dan dikaji dalam menghubung kait kegunaan pelbagai zarah bersaiz nano di dalam komposit. Penambahan Alumina didalam campuran komposit telah meningkatkan kekuatan dielektrik berbanding zarah-zarah yang lain. Purata voltan pecah bagi PP/EPDM/Al2O3, PP/EPDM, PP/EPDM/Organoclay, PP/EPDM/TiO2 and PP/EPDM/BN masing-masing adalah 43.5kV/mm, 41.37 kV/mm, 40.20 kV/mm, 38.09 kV/mm dan 34.04 kV/mm. Seterusnya penyebaran zarah di analisis dan dinilai dengan menggunakan ujian morphologi. Hasil dari ujian, penyebaran zarah Alumina adalah tersebar secara sekata. Manakala pada campuran komposit yang lain, ia telah menunjukkan penggumpulan zarah-zarah. _______________________________________________________________________________________________________ PP/EPDM nanocomposites samples was blended at 50:50 ratios and developed by compounding with and without 5 wt% concentration of Al2O3, TiO2, BN and Organoclay nanofillers. The dielectric constant of each specimen was observed using the Material Analyzer. It was found that, the value of dielectric constant was fairly low at PP/EPDM blend without filler and marginally increases at PP/EPDM blend with Al2O3, TiO2 and BN nanofillers. The compounding of PP/EPDM with Organoclay nanofillers shows, some reduction compared to the virgin PP/EPDM. On the other hand, the result of electric field strength from the breakdown test and Opera-2D’s simulation were evaluated to investigate their relation with the different nanofillers. As a result, the addition of Al2O3 nanofillers into the blend increased the dielectric strength of the composites system compared to others nanofillers. From the average value of electric field strength, it was found that the value of electric field strengths for PP/EPDM/Al2O3, PP/EPDM, PP/EPDM/Organoclay, PP/EPDM/TiO2 and PP/EPDM/BN were 43.5kV/mm, 41.37 kV/mm, 40.20 kV/mm, 38.09 kV/mm and 34.04 kV/mm respectively. Next, the dispersions of fillers were analyzed and interpreted using the SEM morphology test. It was found that the dispersion pattern of Alumina in PP/EPDM/Al2O3’s specimen is homogenously dispersed. Meanwhile, there was an agglomeration of fillers in the PP/EPDM/BN, PP/EPDM/TiO2 and PP/EPDM/Organoclay’s specimen.
