表面処理したセルロースナノファイバー粉末の開発

抄録

Lignocellulose nanofibers synthesized by the wet milling is expected to be used for the filler. However, it is problem that the surface property of cellulose nanofiber is hydrophilic. Therefore, we investigated the effect of surface treatment agent. Cellulose nanofibers were coated with surface-treated precipitated calcium carbonate particles prepared by wet process for disk mill. A suspension of lignocellulose nanofibers was dried and crushed to prepare surface-treated cellulose nanofibers powder. In general, the surface property of cellulose nanofiber is hydrophilic, but it was changed to hydrophobic by coating with surface-treated precipitated calcium carbonate particle.
