The present invention relates to a surface-modified cellulose nanocrystal and a method for producing the same, and more particularly, to a cellulose nanocrystal having a surface modified with an alkyl group, characterized in that the compound represented by Formula 1 and cellulose form an ester bond. will be. In addition, the present invention relates to a polymer composite material using the cellulose nanocrystal whose surface is modified with the alkyl group as an additive. When the surface-modified cellulose nanocrystals according to the present invention are used as an additive to the polypropylene composite material, the physical, chemical and mechanical properties of the composite material can be greatly improved, and thus it is expected to be widely applied in various industrial fields. |
