Abstract

Beberapa parameter electrospinning digunakan untuk mengoptimalkan ukuran nanofiber. Parameter electrospinning yang paling mempengaruhi diameter fiber adalah konsentrasi larutan, DC High Voltage, dan jarak nozzle to collector. Penelitian ini bertujuan untuk memaksimalkan variasi parameter dalam menghasilkan ukuran dan morfologi fiber. Electrospinning menggunakan larutan yang dikenai oleh DC High Voltage sehingga timbul gaya elektrostatik dan medan listrik. Larutan tersebut akan memanjang membentuk kerucut (Taylor Cone). Kemudian terbentuk jet polimer yang mengalami penipisan dan penguapan sehingga terbentuk serat pada collector. Uji SEM (Scanning Electron Microscopy) dilakukan untuk mengetahui diameter dan morfologi dari fiber yang terbentuk. Berdasarkan penelitian yang telah dilakukan, diperoleh kesimpulan bahwa nanofiber terkecil didapatkan pada konsentrasi larutan 5%, DC High Voltage 10 kV, dan jarak nozzle to collector 15 cm. ================ Several parameters in electrospinning can be used to optimize the nanofiber size, this electrospinning parameters that affect the fiber diameter are the liquid concentration, DC High Voltage and Nozzle to Collector distance. This experiment aims to maximizing the parameter of variation in producing the size and morphology of fiber itself. Electrospinning uses the liquid that has been applied with DC High Voltage so the elektrostatik and electric field are happened. Those liquid will be lengthened with cone shaped size (Taylor Cone). And formed the thinning polymer jet that evaporates so the fiber is formed in collector. The Scanning electron microscopy test is conducted to determine the diameter and morphology of the formed fiber. According to this experiment it can be concluded that the smallest nanofiber can be obtained when liquid concentration is at 5% and DC High Voltage is on 10kV and the distance between nozzle and collector is 15 cm.
