    • The present invention relates to polysiloxane nanoparticles having the following properties: an average particle size d50 (measured using REM recordings) in the range of 10-200 nm, a specific surface area Ao of at least 50 m2/g, a pore volume of at least 0.2 cm3/g, an average pore volume d50 of at least 0.8 nm, wherein the particles have groups that contain carbon, which groups are bonded to the silicon at least partially in the form of unsubstituted or substituted alkyl, alkenyl, aryl, arylalkyl, or alkylaryl groups. Said polysiloxane nanoparticles can be produced, among other things, in that either a silazane or a mixture of different silazanes having one or more —[Si(R)(R1)—NR2]— units and/or a silane or a mixture of different silanes having the formula R′x—SiX4-a or an oligosiloxane obtainable by means of hydrolytic condensation of said silane/said silanes or a mixture of such oligosiloxanes are provided in a solvent and brought in contact with a strongly alkaline medium in such a way that the pH is not below 13 after the addition thereof. In specific embodiments, synthesis in acid is also successful.
    • 本发明涉及具有以下特性的聚硅氧烷纳米粒子:10-200nm范围内的平均粒径d50(使用REM记录测定),比表面积Ao为至少50m 2 / g,孔体积为 至少0.2cm 3 / g,平均孔体积d50至少为0.8nm,其中所述颗粒具有含有碳的基团,所述基团至少部分地以未取代或取代的烷基,烯基,芳基,芳烷基 ,或烷基芳基。 可以制备所述聚硅氧烷纳米颗粒,其特征在于,硅氮烷或具有一个或多个 - [Si(R)(R 1)-NR 2] - 单元和/或硅烷或不同的混合物的不同硅氮烷的混合物 具有式R'x-SiX4-a的硅烷或通过所述硅烷/所述硅烷或这种低聚硅氧烷的混合物的水解缩合得到的低聚硅氧烷在溶剂中提供,并以这种方式与强碱性介质接触 加入后pH不低于13。 在具体实施方案中,酸中的合成也是成功的。
