Electrospinning and Electrospraying of Polybutylene Succinate/esterified Cellulose Nanofibril Composites

Cellulose nanofibrils (CNF) were esterified using long-chain fatty acid chlorides (octanoyl chloride, lauroyl chloride, and palmitoyl chloride) and composited with a biodegradable polymer, polybutylene succinate (PBS). The composite material was fabricated into nano-scale fibers and films via electrospinning and electrospraying processes using chloroform as a solvent. The influence of process conditions, CNF type and CNF amount on morphologies were investigated. The diameter of the electrospun fibers was ranged from 648 to 975 nm and fibers with the lowest diameters were produced at 10
