Abstract
Nanovlakna na bazi lignina predstavljaju značajan potencijal za upotrebu u tehničkim primenama kao održiva alternativa konvencionalnim materijalima. U ovoj studiji ispitivano je elektropredenje ligninskih nanovlakana. Poliakrilonitril (PAN) i polivinil alkohol (PVA) su odabrani kao nosec'i polimeri kako bi se olakšao proces elektropredenja. Rastvori lignin/polimer sa različitim odnosima mešanja su elektropredeni pod različitim primenjenim naponima. Morfologija dobijenih nanovlakana je okarakterisana pomoc'u skenirajuc'e elektronske mikroskopije (SEM). Rezultati su pokazali uspešnu proizvodnju ligninskih nanovlakana bez perli korišc'enjem oba nosec'a polimera. Primetno je da su najfinija nanovlakna dobijena sa PAN-om, dok je upotreba PVA omoguc'ila ugradnju vec'eg sadržaja lignina (>80%) unutar nanovlakana bez perli.
Sažetak
Lignin-based nanofibers present significant potential for use in technical applications as a sustainable alternative to conventional materials. In this study, the electrospinning of lignin nanofibers was investigated. Polyacrylonitrile (PAN) and polyvinyl alcohol (PVA) were selected as carrier polymers to facilitate the electrospinning process. Lignin/polymer solutions with varying mixing ratios were electrospun under different applied voltages. The morphology of the resulting nanofibers was characterized using scanning electron microscopy (SEM). The results demonstrated the successful production of bead-free lignin nanofibers using both carrier polymers. Notably, the finest nanofibers were obtained with PAN, whereas the use of PVA enabled the incorporation of a higher lignin content (>80%) within bead-free nanofibers.
