    • The sol-gel templating with the infusion of gas bubbles provides a process for synthesizing polymeric or gel materials while being templated with slow bubbling of various gases into the reacting media upon the polymerization or gelation stage. The process uses a source of gas, which is delivered at a desired rate and pressure via at least one inert tube directly into the reacting solution while the gel is being formed by sol-gel process. The tube(s) have a diameter selected to produce bubbles that result in the desired pore size and the number and placement of the tubes is selected to produce the desired pore structure and surface area in the gel template. The gel may be any gel capable of being formed by sol-gel process. The gas may be selected from carbon dioxide, methane, nitrogen, helium, argon, oxygen, hydrogen, propane, ethane, propylene, ethylene, air, and n-butane and other inert gases.
    • 随着气泡注入的溶胶 - 凝胶模板提供了合成聚合物或凝胶材料的方法,同时在聚合或凝胶化阶段将各种气体缓慢鼓泡到反应介质中进行模板化。 该方法使用气体源,其以期望的速率和压力通过至少一个惰性管直接递送到反应溶液中,同时通过溶胶 - 凝胶法形成凝胶。 管具有选择的直径以产生产生所需孔径的气泡,并且选择管的数量和位置以产生所需的孔结构和凝胶模板中的表面积。 凝胶可以是能够通过溶胶 - 凝胶法形成的任何凝胶。 气体可以选自二氧化碳,甲烷,氮气,氦气,氩气,氧气,氢气,丙烷,乙烷,丙烯,乙烯,空气和正丁烷等惰性气体。
