Electrospun chitosan nanofiber random mats reinforced with cellulose nanowhiskers [Elektronisk resurs] Poster Presentation

• Chitosan is a non-toxic, antibacterial, biodegradable and biocompatible biopolymer used extensively for biomedical applications such as tissue engineering, drug and gene delivery, wound healing etc. Electrospinning of chitosan solution in acetic acid (50%) was carried out at 25 kV, gap distance of 155 mm, flow rate 13 mL/h. Cellulose nanowhiskers having diameters of 5-10 nm and aspect ratio of ≈150, were isolated from microcrystalline cellulose (MCC) and used as the reinforcement in the electrospun random mats. The mats were further crosslinked using genipin to improve mechanical properties. The electrospun fibers had diameters in the range of 130-300 nm. With inclusion of the whiskers decreased 50% of average fiber diameters. The mechanical properties of electrospun mats increased as a function of nanowhisker addition as well as crosslinking. These electrospun mats are expected to find application in wound dressing, burn healing etc.
