“…Namely, it occurs as a consequence of hemicellulose removal from interfibrillar regions, followed by decreased crystallinity, pronounced elementary fibers' liberalization, and increased effective surface area allowing higher availability of cellulose hydroxyl groups as well as storing of water molecules inside fibers' free volume (Ivanovska et al 2019b). hydroxyl groups present at the crystallite surfaces become more exposed and ready to form hydrogen bonds with surrounding amorphous regions.…”

“…Therefore, during the determination of fibers' electro-physical properties, especially in a condition of high humidity, their ability for moisture sorption should be considered since water has a much higher and more stable dielectric constant than fibers (Loss et al 2020). Moreover, previously published data (Ivanovska et al 2019b(Ivanovska et al , 2020 revealed that jute fibers' moisture sorption ability is directly conditioned by their fine structure, i.e. crystallinity indicating that this parameter plays an essential role in understanding the fabrics' electro-physical properties.…”

The electro-physical properties of raw and chemically modified jute fabrics were studied as complex phenomena of the interaction between the fabrics’ chemical composition, crystallinity, moisture sorption, COOH group content, structural characteristics, and frequency of the electric field. At 80% relative air humidity, all chemically modified jute fabrics have 38–179% and 1.7–5.4 times higher dielectric loss tangent and effective relative dielectric permeability compared to unmodified, respectively. To further improve these properties, fabrics were treated with CuSO4 and Cu-based nanoparticles were in situ synthesized on their surface by reduction. A few single Cu-based nanoparticles were observed across the alkali modified fabric’s surface, while single and agglomerated nanoparticles were distributed over the oxidatively modified fabric’s surface. No matter whether metallic Cu or copper oxide (Cu2O or CuO) nanostructures (or their mixtures) are synthesized (proven by XRD), excellent fabrics’ effective relative dielectric permeability is guaranteed. In other words, during the exploitation in specific conditions contributing to copper reduction, the jute fabrics will be able to store 21–163 times more energy from an external electric field than before the exploitation, which further extended their lifetime. On the other hand, with increasing the total content of Cu after the reduction and formation of single and agglomerated Cu-based nanoparticles, the movement of jute structural components’ molecules becomes difficult resulting in lower energy dissipation within the chemically modified than within unmodified fabric. Applied chemical modification and coating with Cu-based nanoparticles enables designing fabrics with predictable electro-physical properties, which is very important from the application point of view.

Pada penelitian ini telah dilakukan penentuan konstanta permitivitas dielektrik bahan kain non woven secara eksperimen dengan menggunakan kapasitansi meter berbasis Arduino Uno dan prinsip kerja kapasitor plat sejajar. Penentuan konstanta permitivitas bahan kain non woven dilakukan dengan cara mengukur nilai kapasitansi yang divariasikan terhadap jarak antara plat yang berisi bahan dielektrik kain non woven. Pengukuran kapasitansi dilakukan dengan prinsip pengisian dan pengosongan kapasitor menggunakan perangkat mikrokontroler Arduino Uno. Proses pengisian dan pengosongan dilakukan dengan menggunakan susunan seri rangkaian resistor-kapasitor (RC) dengan tegangan sumber 5 Volt. Pada eksperimen ini telah digunakan sebuah plat sejajar dengan ukuran 29 × 30 cm sebagai elektroda kapasitor, serta sebuah perangkat resistor dengan ukuran 125 megaOhm. Hasil penelitian menunjukan bahwa perilaku pengisian dan pengosongan perangkat kapasitor plat-sejajar memiliki nilai R square > 0,9, yang menunjukan korelasi cukup baik antara hasil prediksi dan eksperimen pada pengukuran kapasitansi. Terdapat lima bahan dielektrik kain yang ditentukan dengan hasil dari yang terkecil sampai yang terbesar berturut-turut yaitu kain non woven polipropilen 31,44 gsm sebesar 1,0598, kain non woven polipropilen 43,72 gsm sebesar 1,0996, kain non woven polipropilen 52,31 gsm sebesar 1,1288, kain non woven polipropilen 74,12 gsm sebesar 1,1963, kain non woven polipropilen 80,87 gsm sebesar 1,2279. Telah ditemukan hubungan antara parameter gramasi (GSM) kain non woven polipropilen terhadap besaran nilai konstanta dielektrik terukur.
