Abstract: The regenerated wood pulp cellulose (W-RC) was prepared with high purity wood pulp board as raw material and the product was characterized by TEM,FT-IR and XRD.Results indicate that W-RC belongs to the typical nanometer cellulose Ⅱ particles.O/W Pickering emulsion was prepared using caprylic/capric triglycerides (GTCC) as the oil phase and W-RC as the emulsifier.The Pickering emulsions were characterized by optical microscopy,fluorescence microscopy,FE-SEM and rheometer.Results show that W-RC is adsorbed at the oil-water interface and a three-dimensional network structure is formed on and in between oily microspheres from fluorescence microscopy and FE-SEM image.The rheology study illustrates that W-RC and the resulting emulsions feature the typical shear-thinning property of emulsions.W-RC displays excellent emulsifying properties,and a stable emulsion can be obtained when the W-RC mass fraction is 0.6% and even if the dispersed phase volume fraction is as high as 60%.

Key words: Pickering emulsion, regenerated wood pulp cellulose, caprylic/capric triglyceride, rheology
