The surface of wheat straw fiber is modified by means of chemical oxygenation method and the probability of the surface modification on wheat straw fiber was explored in this work. The treated wheat straw fiber with modifier JB and untreated fiber were analyzed by ESCA and the mechanical properties of wheat straw MDF(medium density fiberboard) were measured. The results show that the polarity and reactive activity of the surface of wheat straw fiber are improved by the modification, as well as the mechanical properties of MDF with modified fibers.
