Nanofiber refers to a fibrous material with a diameter of tens of hundreds of nanometers. However, nanofibers have been mainly manufactured by an electrospinning process, which requires expensive equipment and has difficulty in mass production because the production rate is lower than that of other polymer processes. Recently, a "solution blown spinning" process has been introduced, making it possible to manufacture nanofibers at a very high speed by applying air pressure to the outside of the nozzle. In this study, biodegradable polybutylene succinate (PBS) nanofibers were prepared using simple solution blown spinning. From the results, the concentration of PBS had the most significant effect on the spinnability and morphology of PBS nanofibers. Besides, it was found that the prepared nanofibers have hydrophobicity through a high contact angle. Finally, as a result of conducting an oil adsorption experiment using this, it showed a high oil absorption rate of 20 g/g or more. |
