有机/无机纳米复合粒子是一种应用广泛的复合材料,采用细乳液聚合方法是制备此类复合粒子的有效途径,其中分裂/融合过程是一种新型的制备工艺.纳米复合粒子的型态控制是一个非常重要的方面,从热力学角度出发,把界面Gibbs自由能最低这一基本热力学原理应用于计算细乳液聚合、采用新型分裂/融合工艺制备的有机/无机纳米复合粒子平衡型态,并推导了核壳型、半球型、夹心型和分离型复合粒子平衡型态的热力学方程.通过比较特定制备条件下不同形态复合粒子的界面Gibbs自由能,可以预测最稳定的有机/无机纳米复合粒子平衡型态.
Organic / inorganic nano-composite particles is a widely used composite materials, the use of miniemulsion polymerization method is an effective way to prepare such composite particles, which split / fusion process is a new type of preparation process. Is a very important aspect. From the viewpoint of thermodynamics, the basic principle of thermodynamics with the lowest Gibbs free energy at the interface is applied to calculate the equilibrium type of organic / inorganic nanocomposite particles prepared by the miniemulsion polymerization and the new split / fusion process The thermodynamic equations for the equilibrium state of the core-shell, hemispherical, sandwich and separation composite particles can be predicted by comparing the Gibbs free energy of the interface between the different morphology composite particles under the specific preparation conditions, to predict the most stable organic / inorganic nanocomposite particle balance Type.
