摘 要
多面体低聚倍半硅氧烷(Polyhedral Oligomeric Silsesquioxane,简称POSS)是一种具有笼状结构的有机/无机杂化分子。与蒙脱土、二氧化硅等传统的纳米填料不同，POSS具有规整的笼状结构、纳米尺度以及与聚合物良好的相容性，POSS能与聚合物形成真正意义上的分子级复合，提高了聚合物的热稳定性，机械强度，阻燃性，抗氧化，抗老化等性能。
本文首先合成了一种POSS单体(四甲基铵硅氧烷)，并用核磁共振(NMR)，X射线衍射测试(XRD)，热重分析（TGA）等对POSS的结构进行了表征。随后以这种POSS为基础，制备了PP/IFR/POSS纳米复合材料，并对其做了锥形量热仪实验测试，得到了PP/IFR/POSS纳米复合材料的热释放速率(HRR)、质量损失（MLR）、生烟速率（SPR），通过分析了解它们的阻燃性能。本文具体以三章展开：
第一章是前言。描述了POSS的发展和应用等，并详述了目前POSS合成的研究现状，对许多POSS化合物的制备进行了归纳总结。
第二章是四甲基铵硅氧烷和PP/IFR/POSS纳米复合材料的合成。用四甲基氢氧化铵、正硅酸乙酯为原料，采用溶胶-凝胶法制备的八(四甲基铵)笼形倍半硅氧烷(OctaT MA_POSS)。制备足够的POSS后，进一步制备PP/IFR/POSS纳米复合材料。
第三章是四甲基铵硅氧烷和PP/IFR/POSS纳米复合材料的表征与分析。对POSS单体进行了核磁共振、X射线衍射、热重分析等测试；对PP/IFR/POSS纳米复合材料进行了锥形量热仪测试。

ABSTRACT
Polyhedral Oligomeric Silsesquioxane (POSS) is a cage-like organic/inorganic hybrid molecular. Unlike clay and silica, POSS has a well-defined and nanoscale cage-like structure, it is also compatible with polymers. POSS can composite with polymer at molecular level. POSS modified polymers have enhanced properties. It can improved the performance of polymer which is thermal stability, mechanical strength, flame retardant, antioxidant, anti-aging, etc. it is very significant to prepare novel polymer/POSS nanohybrids.
This paper synthesized a kind of POSS monomers (tetramethyl ammonium siloxane), and nuclear magnetic resonance (NMR), X-ray diffraction (XRD) test, thermogravimetric analysis (TGA) had been used to characterize the structure of POSS. Then, on the basis of POSS, PP/IFR/POSS nanocomposites were prepared by means of melt blending, and heat release rate (HRR), mass loss (MLR) provision and smoke generation rate (SPR) were tested by cone calorimeter, which reveal the flame retardant performance of PP/IFR/POSS nanocomposites. The frame structure can be divided into three parts. The first part is an introduction, and the second part is focused on the synthesis of POSS and PP/IFR/POSS nanocomposites. The details of this paper as follows:
Chapter 1 is the preface, which describes the origin, development and application of POSS. Most important, the current research of POSS was described and the preparation of many POSS compounds was summarized.
Chapter 2 is the synthesis of tetramethyl ammonium silicone and PP/IFR/POSS nanocomposites synthesis. Octa(tetramethylammonium) polyhedral oligomeric silsesqioxanes were synthesized by the sol-gel method, using tetramethylammonium hydroxide and tetraethoxysilane as raw material. After synthesizing enough POSS, further production of PP/IFR/POSS nanocomposites.
Chapter 3 is the characterization and analysis of Octa(tetramethylammonium) polyhedral oligomeric silsesqioxanes and PP/IFR/POSS nanocomposites. Taken nuclear magnetic resonance (NMR), X-ray diffraction (XRD),thermogravimetric analysis (TGA) and other test for POSS, Taken cone calorimeter test for PP / IFR / POSS nanocomposite.
