Production of cellulose nanocrystal reinforced gelatin/poly(caprolactone) electrospun nanofiber

Cellulose nanocrystal (CNC) is a natural material which has gained attractions by several research groups. It can be used as a reinforcing material, because of its dramatic mechanical properties. In this article we have synthesized cellulose nanocrystals from cotton waste by controlled hydrolysis in 64% sulfuric acid solution at 50oC for 90 minutes. FTIR, TGA, DLS and SEM results showed that cellulose nanocrystals were produced successfully. CNC reinforced Gelatin/poly(caprolactone) nanofibers were produced by electrospinning with 17 kV voltage, 1 ml/h feeding rate and 15 cm distance from collector. SEM images showed that nanofibers produced showed smooth surface and the average diameter of fibers were 180 nm. FTIR spectroscopy also showed that CNC is incorporated into fiber successfully
