The suitable synthesis conditions of those new products have been studied. The structures of them are affirmed by IR spectroscopy, 1~H NMR,(13)~C NMR and Elemental Analysis;the configurations of them are also analyzed by theoretical calculation of quantum chemistry. Influences of the length of hydrophobic group, the degree of substitution on the solubility, surface activity, emulsifying property, foam property, hygroscopicity and humidity-retaining ability, compatibleness of those new products have been studied in detail.

It is very difficult to eliminate these influence factors completely by conventional treatment. Surface properties and surface treatment of ultrafine red phosphorus and MMT and their interface properties with polymer matrices were studied in this thesis. The results were characterized by GC, FTIR, XRD, DTA, TG, XPS, UV, SEM, TEM and other physical and chemical methods. The main contents are as following: 1. The study of factors influencing ultrafine red phosphorus's invariability and phosphine liberation indicated red phosphorus undergone oxidation and dismutation reaction in air, and trace ion of iron, copper and nickel fastened water absorption and oxidation, in which the effect of copper ion was the most, while aluminium and zinc ion could slow down red phosphorus'oxidation, and silver ion had the best effect on red phosphorus moisture absorption. Inhibitors such as aluminium hydroxide, magnesium hydroxide, organic phenol and ferrous potassuim cyanide had a good effect on reducing red phosphorus moisture absorption and restraining phosphine liberation.
本文围绕纳微米材料的表面处理及其在高聚物基体中的应用这一主题,系统地研究了超细红磷和蒙脱土两种常见材料的表面特性、表面处理方法及其与高聚物基体的界面特性,通过气相色谱、红外光谱、X射线衍射、差热、热重、X射线光电子能谱仪、紫外光谱、扫描电镜、透射电镜等现代分析仪器以及其它物理、化学方法对实验结果进行了表征和分析,全文主要内容如下: 1、对影响超细红磷安定性的因素以及磷化氢的缓释研究表明:红磷在空气中发生缓慢氧化、歧化反应,微量的铜、铁、镍等金属离子增加了它的吸水和氧化速度,其中铜离子的作用最为明显,而铝、锌等离子减慢了红磷的氧化速度,银离子对减少红磷的吸湿性效果最好。
