摘要: 以高纯木浆板为原料制得再生木浆纤维素(W-RC),并用TEM、FT-IR和XRD对其进行表征,说明W-RC属于典型的纳米基纤维素Ⅱ型颗粒。以辛酸/癸酸甘油三酯(GTCC)为油相,W-RC为乳化剂,制得O/W型Pickering乳液,并通过光学显微镜、荧光显微镜、FE-SEM及流变仪对乳液进行表征。荧光显微镜与FE-SEM的结果显示W-RC吸附在油/水界面并在微球表面及微球间形成三维网状结构。流变学表明W-RC及由其稳定的乳液具有典型的剪切变稀特性。W-RC具有优良的乳化性能,在W-RC质量分数为0.6%、分散相体积分数高达60%时,也能得到稳定的乳液。

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
