This article provides an overview of the methods for surface modification based on the use of stable radicals: 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) and its derivatives.

Two approaches are discussed. The first relies on the immobilization of TEMPO moieties on the surface of various materials including silicon wafers, silica particles, organic polymers as well as diverse nanomaterials. Applications of such materials with spin labeled surface/interface, in (electro)catalysis, synthesis of novel hybrid nanostructures and nanocomposites as well as in designing of organic magnets and novel energy storage devices are also included in the discussion.

The second approach utilizes TEMPO and its derivatives for the grafting of polymer chains and polymer brushes formation on flat and nanostructure surfaces via Nitroxide Mediated Radical Polymerization (NMRP). The influence of such polymer modification on surface/interface physicochemical properties is also presented.

使用TEMPO及其衍生物进行表面修饰

本文概述了基于使用稳定基团进行表面改性的方法:2,2,6,6-四甲基哌啶-1-氧基(TEMPO)及其衍生物。

讨论了两种方法。第一种方法是将TEMPO部分固定在各种材料的表面上,这些材料包括硅片,二氧化硅颗粒,有机聚合物以及各种纳米材料。讨论中还包括具有自旋标记的表面/界面的此类材料在(电)催化,新型杂化纳米结构和纳米复合材料的合成以及有机磁体和新型储能装置的设计中的应用。

第二种方法利用TEMPO及其衍生物通过一氧化氮介导的自由基聚合(NMRP)在平面和纳米结构表面上接枝聚合物链和形成聚合物刷。还提出了这种聚合物改性对表面/界面物理化学性质的影响。
