Investigation on the use of cellulose in wood biomass as various new materials has been actively carried out. In particular, studies on cellulose nanofibers and their applications have received much attention. In these studies, TEMPO (2, 2, 6, 6-tetramethylpiperidine-1-oxyl) mediated oxidation of native cellulose included in kraft pulps was conducted to produce TEMPO-oxidized cellulose nanofibers (TOCN). Recently, in the research for the effective use of TOCN, it has been studied for the composite of the hydrophobic TOCN and polymer materials. In this paper, we describe the nanofiber sheet consisting the TOCN composite-type polymer prepared by electrospinning method, which enhanced the strength by complexation with hydrophobic TOCN.
