| description | Fibrous structures are promising candidates for oil–water separation applications. In this study, we have produced poly(styrene-<i>b</i>-isobutylene-<i>b</i>-styrene) thermoplastic elastomeric fibers with the centrifugal spinning fiber production method. The optimal fiber production conditions were achieved when using a 25% <i>w</i>/<i>w</i> solution concentration in an 80/20 tetrahydrofuran/toluene (<i>w</i>/<i>w</i>) solvent system at 8000 rpm rotational speed. The produced fibers were bead-free and smooth-surfaced with a diameter of 3.68 µm. The produced fibers were highly hydrophobic and oleophilic, suggested by a water contact angle of 129° and the instantaneous absorption of the oil droplet. The oil absorption study showed fast absorption kinetics with 94% relative oil uptake after 1 min and a maximum of 16.5 g sunflower oil/g fiber. The results suggest that polyisobutylene-based thermoplastic elastomers could be promising alternatives in oil absorption applications. |
