Modification of NCC for Improving the Wetting Property with Polyurethane

摘要：

　　In this study,different lipophilic groups from 3-aminpropyltriethoxysilane (APTES) and 3-glycidoxypropyltrimethoxysilane(GPTMS) were used to alter the surface structure of nanocrystalline cellulose (NCC).The diversifications of NCC surface resulted from modifiers improved the wetting property between NCC and polyurethane significantly.The modified NCC was characterized by X-ray powder diffraction (XRD).And the wetting property was indicated by contact angle (CA).Epoxy groups from 6% GPTMS led to a 47.6% decline of CA,while the improvement of wetting property from APTES was inconspicuous.
