摘要

采用不饱和聚酯树脂（UPR）对含苯酚酚醛环氧树脂（PNER）的纳米复合材料进行改性，然后采用sasobit和二氧化硅纳米颗粒在不同填料负载下通过多步骤制备工艺进行增强。然后，考察了sasobit和二氧化硅负载量对纳米复合材料力学性能和热性能或形貌的影响。结果表明，二氧化硅纳米颗粒负载量的增加可以改善热性能和机械性能，但二氧化硅负载量增加超过3wt%会导致机械性能下降。在这种情况下，添加sasobit和二氧化硅不仅可以改善纳米复合材料的机械和热性能，还可以改善纳米材料的分散质量和形态。最终，使用价格合理且环保的材料，如sasobit，可以改善纳米复合材料的生产程序或整体质量和性能。

Modification of Phenol Novolac Epoxy Resin and Unsaturated Polyester Using Sasobit and Silica Nanoparticles

Nanocomposites containing phenol novolac epoxy resin (PNER) were modified by unsaturated polyester resin (UPR) and then reinforced using sasobit and silica nanoparticles at different filler loadings via a multi-step manufacturing procedure. Afterward, effect of sasobit and silica loadings either on mechanical and thermal properties or on morphology of nanocomposites were examined. Results showed that increase in silica nanoparticles loading can improve both thermal and mechanical properties, but increase in silica loading more than 3 wt% can lead to decrease in the mechanical properties. In this case, addition of sasobit along with silica not only can improve the mechanical and thermal properties but also it can lead to improve in dispersion quality and morphology of nanocomposites. Eventually, with affordable and environmentally friendly materials such as sasobit, either production procedure or the overall quality and properties of nanocomposites can be improved.

期刊介绍： Polymers from Renewable Resources, launched in 2010, publishes leading peer reviewed research that is focused on the development of renewable polymers and their application in the production of industrial, consumer, and medical products. The progressive decline of fossil resources, together with the ongoing increases in oil prices, has initiated an increase in the search for alternatives based on renewable resources for the production of energy. The prevalence of petroleum and carbon based chemistry for the production of organic chemical goods has generated a variety of initiatives aimed at replacing fossil sources with renewable counterparts. In particular, major efforts are being conducted in polymer science and technology to prepare macromolecular materials based on renewable resources. Also gaining momentum is the utilisation of vegetable biomass either by the separation of its components and their development or after suitable chemical modification. This journal is a valuable addition to academic, research and industrial libraries, research institutions dealing with the use of natural resources and materials science and industrial laboratories concerned with polymer science.
