摘要:

以疏水性ZnO粒子和亲水性Fe3O4粒子稳定的W/O/W型双重Pickering乳液为模板, 制备了具有空心结构的无机-有机复合微球. 采用X射线衍射(XRD)仪、 扫描电子显微镜(SEM)、 X射线能谱仪(EDS)、 傅里叶变换红外光谱(FTIR)仪及光学显微镜等对制备的无机粒子、 乳液和复合材料进行了表征. 结果表明, 制备了ZnO和Fe3O4 2种无机粒子, 油酸能够对ZnO进行有效的疏水改性, 改性后的接触角为84.3°. 制备的双重Pickering乳液稳定性好、 粒径分布较宽(50~200 μm), 以该双重乳液为模板制备的无机-有机复合材料为空心球形结构, 粒径范围为100~200 μm.

Abstract:

Inorganic-organic composite microspheres with hollow structure were prepared using W/O/W double Pickering emulsions stabilized with hydrophobic ZnO particles and hydrophilic Fe3O4 as templates. The inorganic particles, emulsions and composite materials were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM), Energy dispersive spectrometer(EDS), Fourier transform infrared spectroscopy(FTIR) and optical microscopy. The results showed that the two inorganic particles, ZnO and Fe3O4, were prepared. Oleic acid could effectively modify ZnO with a contact angle of 84.3°. The prepared double Pickering emulsion had good stability and wide particle size distribution, ranging from 50 μm to 200 μm. The inorganic-organic composite material prepared using the double emulsion as template is hollow spherical structure with particle size between 100 and 200 μm.
