Abstract

The electret properties of polypropylene (PP) and nanoclay nanocomposites containing various percentages of Dk1 brand nanoclay were investigated at different temperatures and polarization voltages. The effective surface density (σef) of the accumulated charges in the resulting electret materials depends on the amount of Dk1. σef increases as Dk1 increases, and a decrease is observed after 10%. The deterioration of electret properties with additive amounts exceeding 10% can be explained by the aggregation of the nanocomposites. Dk1 particles added to PP also behave like macrodipoles, manifesting themselves through dipole relaxation processes. After electrothermopolarization, the σef of electret materials depends on Tp and Ep. As Tp increases, maximum values of σef are observed at small values of Ep.

Özet

Polipropilen (PP) ve buna dayalı farklı yüzdelerde Dk1 marka nanokil içeren nanokil nanokompozitlerin elektret özellikleri farklı sıcaklıklarda ve polarizasyon voltajlarında incelenmiştir. Elde edilen elektret malzemelerdeki biriken yüklerin etkin yüzey yoğunluğu (σef), Dk1 miktarına bağlıdır. Dk1 arttıkça σef artmakta ve %10'dan sonra azalma görülmektedir. %10'ı aşan katkı maddesi miktarıyla elektret özelliklerinin bozulması, nanokompozitlerin kümeleşmesiyle açıklana bilir. PP′ye eklenen Dk1 parçacıklar da makrodipollar gibi davranır, dipol gevşeme süreçlerinin meydana gelmesiyle kendini gösterir. Elektrotermopolerizasiyadan sonar elektret malzemelerin σef′si Tp ve Ep′ye bağlıdır. Tp artdıqca, σef′nin maksimum değerleri küçük Ep değerlerinde gözlenilir.
