Abstract

The present work consists the elaboration and the rheological behaviors of nanocomposite (NGTHTPTBAE/MDA/TSP) in the presence of the epoxy resin nanoglycidyl trihydrazine 4.4.4-tripropoxy tribisphenol A of ethylene (NGTHTPTBAE), methylene dianiline (MDA) and trisodium phosphate (TSP) used as filler. Furthermore, we have studied the performance of nanocomposites (NGTHTPTBAE/MDA/TSP) crosslinked by methylene dianiline and formulated by trisodium phosphate at different percentages. Then, the storage modulus G' and the loss modulus G'' (or tanδ = G''/G') are established as a function of the temperature. From these dependencies, we determined the glass transition temperature or tanδ maximum. Moreover, tan δ > 1 for liquid-like materials and it becomes lower than unity for solid-like materials. Finally, the dispersion of the trisodium phosphate incorporated into various prepared nanocomposite (NGTHTPTBAE/MDA/TSP) was determined using the scanning electron microscope (SEM).

亚甲基二苯胺交联磷酸三钠制备环氧聚合物及其纳米复合材料（NGTHTPTBAE/MDA/TSP）的形态和流变学研究

本工作详细介绍了环氧树脂纳米缩水甘油基三肼4.4.4-三丙氧基三苯酚A（NGTHTPTBAE）、亚甲基二苯胺（MDA）和磷酸三钠（TSP）作为填料时纳米复合材料（NGTHTPPBAE/MDA/TSP）的流变行为。此外，我们还研究了由亚甲基二苯胺交联并由磷酸三钠以不同比例配制的纳米复合材料（NGTHTPTBAE/MDA/TSP）的性能。然后，储能模量G’和损耗模量G’’（或tanδ=G’’/G’）被建立为温度的函数。根据这些相关性，我们确定了玻璃化转变温度或tanδ最大值。此外，类液体材料的tanδ>1，类固体材料的tanΔ低于1。最后，利用扫描电子显微镜（SEM）测定了磷酸三钠在各种制备的纳米复合材料（NGTHTPTBAE/MDA/TSP）中的分散度。
