Nanofibers of polyaniline and oligoanilines of controlled molecular weight, e.g., tetraaniline, octaaniline, and hexadecaaniline, are synthesized using a versatile high ionic strength aqueous system that permits the use of H(2)O(2) with no added catalysts as a mild oxidizing agent. Films of oligoanilines deposited on plastic substrates show a robust and reversible chemiresistor response to NO(2) vapor at room temperature in ambient air (100-5 ppm).
通过一种通用的高离子强度水性体系合成了具有可控分子量的聚苯胺和低聚苯胺（如四苯胺、八苯胺和十六苯胺）的纳米纤维，该体系允许在不添加催化剂的情况下使用H₂O₂作为温和的氧化剂。沉积在塑料基板上的低聚苯胺薄膜在室温下的环境空气中（100 - 5 ppm）对NO₂蒸汽表现出强烈且可逆的化学电阻响应。
