以六氯环三磷腈和4,4’-(9-芴)二苯酚为共聚单体,三乙胺为缚酸剂,乙腈为溶剂,通过一步沉淀聚合制备了疏水性的交联聚(环三磷腈-co-4,4’-(9-芴)二苯酚)(PZHF)微球,通过傅立叶变换红外光谱仪(FTIR)、X射线光电子能谱仪(XPS)和扫描电子显微镜(SEM)对微球的化学结构和形貌进行了表征;进一步以该微球为稳定剂,通过包覆水滴成功制备了液体弹珠,研究了液体弹珠的静态稳定性以及共聚物微球在液体弹珠表面的分布情况,并考察了液体弹珠的气体透过性.结果表明,PZHF微球具有高度交联的有机-无机杂化结构,平均粒径为1.3μm,且微球表面较为粗糙,具有疏水性;用其包覆水滴可得到稳定的液体弹珠,微球在气-液界面上的排列较为疏松,使液体弹珠具有独特的气体透过性,外界气体可通过液体弹珠表面进入内部水相而不破坏弹珠自身的结构.
Using hexachlorocyclotriphosphazene and 4,4 ’- (9-fluorene) diphenol as comonomers, triethylamine as acid-binding agent and acetonitrile as solvent, one-step precipitation polymerization was used to prepare hydrophobic cross-linked poly Cyclotriphosphazene-co-4,4’- (9-fluorene) diphenol) (PZHF) microspheres were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy ) Were used to characterize the chemical structure and morphology of the microspheres. With the microspheres as the stabilizer, the liquid marbles were successfully prepared by coating the water droplets. The static stability of the liquid marbles and the effect of the copolymer microspheres on the liquid The distribution of the marbles and the gas permeability of the liquid marbles were investigated.The results showed that the microspheres had a highly cross-linked organic-inorganic hybrid structure with an average particle diameter of 1.3μm and the surface of the microspheres was relatively rough , With hydrophobic; coated with water droplets can be obtained stable liquid marbles, microspheres arranged in the gas-liquid interface is more loose, so that the liquid marbles have a unique gas permeability, the outside air through the liquid marbles The surface enters the internal water phase without disrupting the structure of the marbles themselves.
