Abstract

In this paper, the effects of synthesized TiO2 nanoparticles and polyethylene glycol (PEG) on mechanical, morphological, and thermal properties of unsaturated polyester (UPE) based nanocomposites were studied. The TiO2 nanoparticles were synthesized by sol-gel method. The UPE/PEG/TiO2 nanocomposites were prepared at various concentrations of synthesized TiO2 nanoparticles and PEG by direct mechanical mixing technique. The synthesized TiO2 nanoparticles were mixed with UPE resin through ultra-sonication in different weight fractions (wt%), namely, 0 wt%, 0.5 wt%, 0.75 wt%, and 1 wt%. The PEG was considered in different wt% fractions such as 5 wt%, 10 wt%, 15 wt% for preparing UPE/PEG/TiO2 nanocomposite. Consequently, chemical structure of nanocomposite was investigated with FT-IR analyses. Also, the TiO2 nanoparticles and optimized samples were characterized by TGA, SEM and XRD analyses. The results obtained by TGA, FT-IR, SEM and XRD analyses exhibited an improvement of thermal and mechanical properties of the nanocomposites containing synthesized TiO2 nanoparticles (0.5 wt%) and PEG (10 wt%) compared to pristine polyester.

聚酯/聚乙二醇/TiO2纳米复合材料力学性能研究

本文研究了合成的TiO2纳米粒子和聚乙二醇(PEG)对不饱和聚酯(UPE)基纳米复合材料的力学、形态和热性能的影响。采用溶胶-凝胶法制备了TiO2纳米颗粒。采用直接机械混合的方法，制备了不同浓度的TiO2纳米粒子和PEG纳米复合材料。将合成的TiO2纳米粒子以不同重量分数(wt%)，即0 wt%、0.5 wt%、0.75 wt%和1 wt%，通过超声波与UPE树脂混合。在制备UPE/PEG/TiO2纳米复合材料时，考虑了不同wt%的PEG，如5 wt%、10 wt%、15 wt%。利用傅里叶变换红外光谱分析了纳米复合材料的化学结构。并通过TGA、SEM和XRD分析对TiO2纳米粒子和优化后的样品进行了表征。TGA, FT-IR, SEM和XRD分析结果表明，与原始聚酯相比，含有合成TiO2纳米粒子(0.5 wt%)和PEG (10 wt%)的纳米复合材料的热性能和力学性能都有所改善。
