This research focused on the improvement of the physical properties of biopolyurethane (BPU) using cellulose nanowhisker (CNW). For the study, BPU was synthesized by one-shot polymerization from corn sugar-based polyol and methylene diiscocyanate (MDI). CNW was prepared via conventional acid hydrolysis of pulp using sulfuric acid. The synthesized BPU was mixed with the CNW and then electrospun. The...
In the study, cellulose nanowhisker (CNW) was prepared by acid hydrolysis of microcrystalline cellulose (MCC) and the both celluloses, CNW and MCC were carbonized at different temperatures. The structures of the carbonized celluloses were characterized using transmission electron microscope, X-ray diffraction and Raman spectroscopy. Comparing with the carbonized MCC, the carbonized CNW showed lower...
