Abstract

Telah dilakukan penelitian untuk menganalisis dielektrisitas lateks cair dan cup lumb dan serapan optis lapisan tipis lateks. Nilai konstanta dielektrik lateks hasil pengujian berbasis gelombang audio dengan variasi frekuensi, adalah 3,74   untuk lateks cair dan 10,4 untuk cup lumb dengan loss tangent masing-masing 6,12 dan 7,81. Data spektrum UV-Vis dan FT-IR lapisan tipis lateks yang dipreparasi menggunakan teknik spin coating, menunjukkan konsentrasi poli(cis-isoprana) dalam sampel sangat besar.
