In addition to the cationic twin polymerization on polar surfaces such as SiO2 or cellulose the second part of the project will focus on the base catalyzed twin polymerization of 2,2'-Spirobis[4H-1,3,2]-benzodioxasilin (1) and derivatives on carbon surfaces of graphite, graphene, carbon nanotubes, and amorphous carbon as well as metal particles. The twin polymerization of 1 catalyzed with bases like diazabicyclo[2.2.2]octane (DABCO) or 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) is conducted to coat graphit particles as well as to obtain new intercalation compounds for the integration of different carbon morphologies into carbon/carbon nanocomposites. An important goal is the synthesis of graphene/microporous glass-like carbon hybrid materials as electric conducting composites which can be applied as electrode materials in energy storage applications. In this context it is as well subject of investigation if heteroatom doped carbon is accessible via base catalyzed twin polymerization. For this aspect new twin monomers have to be synthesized and investigated.The prefunctionalization of metal surfaces like copper with secondary amines (e.g. pyrrolidine) should be used to extend the surface twin polymerization on metal surfaces and integrate them into carbon matrices.

除了在Sio2或纤维素等极性表面上的阳离子双聚合聚合外，该项目的第二部分还将集中在基础上催化2,2'-螺旋蛋白的双胞胎聚合[4H-1,3,2] - 苯甲二氧化裔卡西素（1）及其在碳纤维上的碳纤维，焦虑的碳含量和碳纤维的含量。用二氮氮氮气[2.2.2]辛烷（Dabco）或1,8-二扎布里克洛[5.4.0] Undec-7-Ene（DBU）等碱基的1个催化的双聚合物化，以涂上石墨素材涂上石墨颗粒，以便获得不同碳或碳体内的新的互互插入化合物。一个重要的目标是将石墨烯/微孔玻璃样的碳杂种材料作为电导材料的合成，可以在能源储能应用中用作电极材料。在这种情况下，如果可以通过催化的双聚合聚合能够访问杂原子掺杂碳，那么研究也是如此。在这一方面，必须合成新的双单小体。应使用金属表面（例如铜）与次级胺（例如吡咯烷）（例如吡咯烷）的术前功能来扩展金属表面上的表面双聚合并将其整合到碳基质中。
