Abstract

The effect of nanofiller (NF) additives containing copper oxide nanoparticles (NPs) stabilized by a polymer matrix of maleated polyethylene (MAPE), obtained by the mechanochemical method, on the properties of composites based on high-pressure polyethylene (LDPE) has been investigated by X-ray diffraction (XRD) and thermographic (TGA) analysis. The improvement in strength, deformation, and rheological properties, as well as the thermo-oxidative stability of the obtained nanocomposites, has been revealed, which is associated with the synergistic effect of the interaction of copper nanoparticles with maleic groups of MAPE. It has been shown that LDPE-based nanocomposites can be processed both by pressing and by injection molding and extrusion, which expands the scope of its application.

含金属纳米填料的高压聚乙烯纳米复合材料的性能

摘要

研究了通过机械化学方法获得的，包含由马来酸化聚乙烯（MAPE）的聚合物基质稳定的氧化铜纳米颗粒（NPs）的纳米填料（NF）添加剂对基于高压聚乙烯（LDPE）的复合材料性能的影响通过X射线衍射（XRD）和热成像（TGA）分析。揭示了所获得的纳米复合材料的强度，变形和流变性质以及热氧化稳定性的改善，这与铜纳米颗粒与MAPE的马来酸基团相互作用的协同作用有关。已经表明，基于LDPE的纳米复合材料可以通过压制以及通过注射成型和挤出来加工，这扩大了其应用范围。
