Fluoroscence Phenomena-New Properties of Hexakis(4-Aminophenoxy)Cyclotriphosphazene

Investigations of the absorption and fluorescence spectra of hexakis (4-aminophenoxy)- cyclotriphosphazene at room temperature in three solvents of different polarity (N, N-dimethyl- formamide, tetrahydrofuran and toluene) have been conducted. And fluorescence lifetimes of these three solutions were also measured. Major reasons of such spectral behavior are discussed.

六(4-氨基苯氧基)环三磷腈用于羊毛织物的阻燃研究

将六氯环三磷腈的衍生物六(4-氨基苯氧基)环三磷腈通过浸-轧-烘的方法用于羊毛织物的阻燃整理。采用傅里叶红外光谱仪对整理后的羊毛织物进行了表征;并采用热重分析、极限氧指数、垂直燃烧测试、扫描电镜对整理前后羊毛织物的阻燃性能及残渣形貌进行了研究。结果表明,六(4-氨基苯氧基)环三磷腈和羊毛之间存在化学键结合;该阻燃剂能显著提高羊毛织物的成炭性能,凝聚相的阻燃效果优异;整理后的羊毛织物垂直燃烧损毁长度和极限氧指数明显提高,且具有优异的耐水洗牢度。
