以季戊四醇/磷腈为引发剂，通过4-缩水甘油氧基TEMPO与二缩水甘油醚的阴离子开环共聚反应合成了一种交联型聚(4-缩水甘油氧基TEMPO)。聚醚/SWCNT复合层具有几十微米厚的快速可逆电荷存储能力，尽管SWCNT的含量很低，为10%，比以前报道的TEMPO取代的聚甲基丙烯酸甲酯的含量更接近渗流极限。
A crosslinked poly(4-glycidyloxy TEMPO) was synthesized via anionic ring-opening copolymerization of 4-glycidyloxy TEMPO and a diglycidyl ether using a pentaerythritol/phosphazene base initiator. A fast and reversible charge storage capability was established for the polyether/SWCNT composite layer with a large layer thickness of several tens of micrometres, despite the low SWCNT content of 10% which was much closer to the percolation limit than the amount required for the previously reported TEMPO-substituted polymethacrylate.
