    Abstract: The present invention is a method of producing porous beads, which comprises the steps of providing a first liquid phase comprising a bead matrix material and essentially edgy templating particle(s), said particle(s) being treated with a surface modifying agent; providing a second liquid phase which is immiscible with the first liquid phase; contacting the first phase and the second phase under conditions resulting in an emulsion of droplets comprised of the first liquid phase dispersed in the continuous second liquid phase; transforming the droplets to mesoporous beads by solidification of the liquid; and removing the templating particle(s) from the beads without causing any essential change of the surrounding bead, whereby hierarchical networks of pores are provided in the beads.

    Abstract translation: 本发明是一种生产多孔珠的方法,其包括以下步骤:提供包含珠粒基质材料和基本上前提的模板颗粒的第一液相,所述颗粒用表面改性剂处理; 提供与第一液相不混溶的第二液相; 在产生由分散在连续第二液相中的第一液相组成的液滴的乳液的条件下使第一相和第二相接触; 通过液体凝固将液滴转变成中孔珠粒; 并且从珠粒中除去模板颗粒,而不会引起周围珠粒的任何必需的变化,由此在珠粒中提供分级网孔。
