Abstract

Penelitian ini mengeksplorasi fabrikasi dan karakterisasi tinta konduktif berbasis nanokomposit perak-polimer untuk aplikasi elektroda, dengan memanfaatkan nail polish sebagai agen pengikat (binder) alternatif. Nanopartikel perak (AgNPs) disintesis menggunakan metode poliol, menghasilkan partikel dengan struktur kristal face-centered cubic (FCC) dan ukuran rata-rata sebesar 76,11 nm. Formulasi tinta konduktif optimum diperoleh pada rasio AgNPs terhadap nail polish sebesar 3:1. Tinta kemudian dideposisikan pada empat jenis substrat (kaca, PET, kertas, dan kain) sebelum menjalani proses sintering suhu rendah bertahap pada variasi 60 °C, 70 °C, dan 100 °C. Hasil penelitian mengonfirmasi bahwa sintering efektif menurunkan resistansi secara signifikan melalui mekanisme pembentukan leher (neck formation) antarpartikel. Substrat PET menunjukkan performa konduktivitas paling unggul dengan nilai resistivitas 7,35 × 10⁻⁴ Ω·m, sedangkan substrat kertas dan kain memiliki resistivitas lebih tinggi akibat morfologi permukaannya yang berpori. Pengujian stabilitas mekanik (bending test) mengungkapkan bahwa substrat PET memiliki stabilitas dan pemulihan jalur konduktif terbaik. Sebaliknya, uji adhesi (tape test) menunjukkan bahwa kekuatan rekat sangat bergantung pada morfologi permukaan substrat, di mana substrat kain memiliki adhesi terbaik, sedangkan PET memiliki adhesi terlemah karena permukaannya yang halus dan tidak berpori

This study explores the fabrication and characterization of conductive ink based on a silver-polymer nanocomposite for electrode applications, utilizing nail polish as an alternative binder. Silver nanoparticles (AgNPs) were synthesized via the polyol method, yielding particles with a face-centered cubic (FCC) crystal structure and an average size of 76.11 nm. The optimal conductive ink formulation was achieved at an AgNP-to-nail polish ratio of 3:1. The ink was then deposited onto four types of substrates (glass, PET, paper, and fabric) before undergoing a stepwise low-temperature sintering process at varying temperatures of 60 °C, 70 °C, and 100 °C. The results confirm that sintering effectively reduces resistance through the mechanism of interparticle neck formation. The PET substrate exhibited superior conductivity performance with a resistivity of 7.35 × 10⁻⁴ Ω·m, while paper and fabric substrates showed higher resistivity due to their porous surface morphology. Mechanical stability testing (bending test) revealed that the PET substrate has the best conductive pathway recovery. Conversely, adhesion testing (tape test) demonstrated that adhesion strength is highly dependent on the substrate's surface morphology; the fabric substrate exhibited the best adhesion, while PET showed the weakest due to its smooth, non-porous surface.
