Abstract

The influence of additions of nanofillers (NF) containing nanoparticles of copper and zinc oxides, stabilized by a polymer matrix of high pressure polyethylene, prepared by mechanochemical method on peculiarities of structure and properties of the metal-containing nanocomposites on the basis of epoxy diane resin (ED-20) by the methods of differential-thermal (DTA) and IR spectral (IRS), and X-ray diffraction (XRD) analyses has been investigated. It has been shown that introduction of metal-containing NF in composition with ED-20 shifts the cold curing reaction temperature from 90 to 75°C and hot curing from 125 to 100°C and favors increase in its thermal stability, which is confirmed by growth of activation energy of thermal-oxidative destruction (E_a) from 210 to 225 kJ/mol. It has been shown that the nanoparticles of copper oxide increase the thermal properties of ED-20 and are the catalysts of the curing reaction as evidenced by the height of the peak on the curing curve. In this case, the nanoparticles of zinc oxide hardly influence the thermal properties of nanocomposites on the basis of ED-20.

基于环氧二烷树脂的含金属纳米复合材料的制备及性能研究

摘要

机械化学方法制得的，由高压聚乙烯的聚合物基体稳定的，含有铜和氧化锌纳米粒子的纳米填料（NF）对基于环氧二烷树脂的含金属纳米复合材料的结构和性能的特殊性的影响（ED-20）通过差热（DTA）和红外光谱（IRS）的方法进行了研究，并研究了X射线衍射（XRD）分析。已经表明，在具有ED-20的组合物中引入含金属的NF将冷固化反应温度从90℃移至75℃，并将热固化反应温度从125℃移至100℃，并有利于提高其热稳定性，这通过以下方法得到证实：热氧化破坏活化能的增长（E _a）从210至225 kJ / mol。已经表明，氧化铜的纳米颗粒提高了ED-20的热性能，并且是固化反应的催化剂，如固化曲线上的峰高所证明的。在这种情况下，基于ED-20，氧化锌的纳米颗粒几乎不影响纳米复合材料的热性能。
