The van der Waals induced supramolecular organization of hydrophobic tetrahedral units in the course of hydrolytic polycondensation
摘要:
本文介绍了四面体前驱体在四个方向上的水解聚合。在硅处发生的水解缩聚产生了高度缩聚的固体(约 100%)。通过 X 射线粉末衍射法和微米尺度(双折射实验)实验,获得的固体呈现出纳米尺度的组织结构。与交联胶体的取向相对应的光轴测定显示出一种反胶束型几何结构。因此,四面体单元的自组织受到介质亲水性差的控制。

This paper describes the hydrolytic polymerization of a tetrahedral precursor in the four directions. The hydrolytic polycondensation occurring at silicon led to highly polycondensed solids (around 100%). The solids obtained exhibited an organization at the nanometric scale evidenced by X-ray powder diffraction and another at the micrometric scale (birefringence experiments). The optical axis determination which corresponds to the orientation of the cross-linked colloids exhibits an inverse micelle type geometry. Thus the self-organization of the tetrahedral units is controlled by the poor hydrophilicity of the medium.
