摘要

Nanophase Mn(VII) oxide (NM7O) is a stable and strong Lewis acid and Mn(III) oxide (NM3O) is a good electron donor or acceptor depending on the environmental conditions. These minerals are synthesized reacting 1,4 phenylenediamine compound with Mn(II) mineral at a specified pH. This is a single step, simple and rapid process. Also, Mn(VII) oxide and Mn(III) oxide are violet and green colored respectively, and coupled with distinct visible band spectra make it possible to develop 'Smart Fabrics'. The NM7O can exist in aerosol, solution, or solid support. The NM3O is synthesized on ion exchangers, e.g., clays and zeolites, as the pure NM3O dissolves in acidic pH. The research shows that NM7O has capacity to destroy Lewis bases, e.g., N, S, O and P containing lone pairs of electrons including oxidation of mustard gas and sarin gas surrogates, and Toxic Industrial Chemicals (TICs). The NM7O is effective in both polar and non-polar solvents, the redox reaction occurs on its surfaces, and no Mn is released into the solvent. Tests have shown that clay coated Mn(III) oxide is a good copper and brass polisher. More research is being conducted to develop new applications. The spent NM7O and NM3O can be disposed of safely in a municipal landfill. The NM7O-clay were incorporated into different nonwoven fabrics, e.g., needle-punched cotton nonwoven, a through air bonded cotton/PLA web and a meltblown polyurethane web, and evaluated for their performance. The air permeability data indicates that these webs have good permeability and these values did not change due to incorporation of NM7O coated clay. Studies show that through air bonded cotton/PLA web coated NM7O-clay was effective in polishing silver, odor control, and protection against Chemical Warfare Agents (CWAs) and Toxic Industrial Chemicals (TICs). Furthermore, the NM7O incorporated reactive garments will have both military and civilian applications including for HazMat- and first response-team.

NM7O在极性和非极性溶剂中均有效，氧化还原反应在其表面上发生，并且没有Mn释放到溶剂中。测试表明，粘土涂覆的Mn（III）氧化物是一种良好的铜和黄铜抛光剂。正在进行更多的研究以开发新的应用程序。用过的NM7O和NM3O可以在市政垃圾填埋场中安全处置。将NM7O-粘土掺入不同的非织造织物中，例如针刺棉非织造织物，通气粘合棉/ PLA网和熔喷聚氨酯网，并评估其性能。空气渗透性数据表明这些纤维网具有良好的渗透性，并且由于引入了NM7O涂覆的粘土，这些值没有改变。研究表明，通过空气粘合的棉/ PLA纤维网涂覆的NM7O粘土在抛光银，控制气味和防止化学战剂（CWA）和有毒工业化学品（TICs）方面有效。此外，结合了NM7O的反应性服装将在军事和民用领域都得到应用，包括HazMat和第一反应小组。
