Abstract

Electrospinning memiliki banyak keunggulan dikarenakan pada peralatannya yang tergolong cukup murah untuk dapat memproduksi fiber berukuran mikro hingga nano, selain itu proses untuk fabrikasi nanofiber-nya cukup sederhana. Meskipun proses fabrikasi nanofiber pada electrospinning sederhana, ada beberapa parameter penting yang perlu diperhatikan. Nanofiber telah banyak diaplikasikan dalam berbagai bidang, namun di sisi lain ketidaksempurnaan pada nanofiber hasil fabrikasi merupakan sebuah hambatan untuk menghasilkan kualitas textural properties yang baik, hambatan tersebut diantaranya dapat berupa beads terhadap nanofiber yang dihasilkan. Untuk memperbaiki properties nanofiber, salah satunya adalah dengan memvariasikan konsentrasi surfaktan. Fabrikasi nanofiber dilakukan dengan menggunakan bahan polimer PVA (Polyvinyl Alcohol), dan surfaktan Triton X-100 dengan variasi konsentrasi surfaktan dari 0, 3, 7 dan 10 wt.%. Pada proses electrospinning, larutan precursor akan diberi tegangan sehingga muncul medan listrik dan gaya elektrostatis, kemudian larutan precursor akan memanjang membentuk kerucut yang disebut taylor cone, lalu terbentuk jet polimer yang mengalami jet thinning dan jet solidifaction sehingga terbentuk fiber pada kolektor. Karakterisasi dilakukan dengan metode pengujian Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD) dan Fourier Transform Infra-Red (FTIR). Berdasarkan hasil penelitian dari karakterisasi SEM dan XRD, dihasilkan nanofiber yang seragam dan memiliki crystallite size terkecil pada konsentrasi surfaktan 7 wt.% dan pada konsentrasi ini merupakan hasil nanofiber yang paling optimal diantara konsentrasi surfaktan yang lainnya. Kemudian pada hasil karakterisasi FTIR menunjukan bahwa nanofiber yang dihasilkan tidak terkontaminasi bahan pengotor serta efek surfaktan Triton X-100 terhadap nanofiber yang dihasilkan tidak mengubah intrinsic properties pada precursor secara signifikan. Surfaktan Triton X-100 terbukti memiliki dampak terhadap textural properties nanofiber karena dapat mengurangi beads pada hasil fabrikasi nanofiber, serta surfaktan ini dapat meningkatkan homogenitas pada pelarutan precursor.

Electrospinning has many advantages because the equipment is relatively cheap to produce micro to nano-sized fibers. besides that, the process for fabricating nanofibers is quite simple. Although the nanofiber fabrication process in electrospinning is simple, there are several important parameters that need to be considered. Nanofibers have been widely applied in various fields, but on the other hand, imperfections in fabricated nanofibers are an obstacle to producing good quality properties, such as beads on the resulting nanofiber. To improve the textural properties of nanofibers, one of them is by varying the surfactant concentration. Nanofiber fabrication was carried out using polymeric PVA (Polyvinyl Alcohol) and Triton X-100 surfactant with various surfactant concentrations of 0, 3, 7 and 10 wt.%. In the electrospinning process, the precursor solution will be given a voltage so that an electric field and electrostatic force appear, then the precursor solution will form a cone called taylor cone, then a polymer jet is formed which undergoes jet thinning and jet solidifaction to form fibers in the collector. The characterization was carried out using the Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD) and Fourier Transform Infra-Red (FTIR) test methods. Based on result of the research of SEM and XRD characterization, the nanofiber produced was uniform and had the smallest crystallite size at surfactant concentration of 7 wt.% and at this concentration the nanofiber yielded the most optimal concentration of other surfactants. Then the results of FTIR characterization showed that the result of the nanofiber was not contaminated with impurities and the effect of Triton X-100 surfactant on the resulting nanofiber did not significantly change the intrinsic properties of the precursor. Triton X-100 surfactant has been shown to have an impact on nanofiber textural properties because it can reduce beads on the nanofiber fabrication, and this surfactant can increase the homogeneity of dissolving precursors.
