Evaluation of wetting, structural and thermal properties of electrospun nanofibers at different pineapple leaf fiber / polyethylene terephthalate ratios

In this study, pineapple leaf fiber and polyethylene terephthalate electrospun nanofibers were produced via electrospinning process. Six ratios of fiber/polyethylene terephthalate, namely 1/10; 1/7,5; 1/5; 1/1 1,3/1 prepared their wetting, structural thermal properties characterised. Wetting sample studied using contact angle measurement. X-Ray Diffraction, differential scanning calorimetry thermogravimetric analysis conducted to get better understanding on the its properties, respectively. The results revealed that increasing content simultaneously increased ability adsorb water as shown by lower degree with 81,6° adsorption time 15 seconds. An increase in ratio did not change peak position Diffraction no new peaks observed for any sample. However, at 23° samples exhibited higher intensity compared pure terephthalate. Thermal obtained from suggested influenced ratio. Overall, displayed optimum performance.
