The structurally different bismaleimides (BMIs) such as 4,4’-bismaleimidodiphenyl ether (BMIE), 4,4’-bismaleimidodiphenyl sulphone (BMIS) and 4,4’-bismaleimidodiphenyl methane (BMIM) were synthesized. The materials graphite (G), graphene oxide (GO) and washed graphene oxide (WGO) particles are separately blended (3% w/w) with BMIs and thermally polymerized under appropriate conditions. The effects of the presence of the nanoparticles in BMIs were investigated using Differential Scanning Calorimetry (DSC). The DSC results show that the blended nanoparticles alter both the cure exotherm and the enthalpy of curing of the BMIs. Thermogravimetric analysis (TGA) was employed to understand the thermal stability of the cured pure BMIs and their blends with nanoparticles. The presence of the nanoparticles in the crosslinked BMIE matrix shifts the onset of the thermal degradation temperature to higher temperature region (around 15 °C). Among all the materials investigated, the nanoparticles incorporated BMIS increases the char residue. This is due to the efficiency of the physical dispersion and the possible chemical interactions shown by nanoparticles in the cured bismaleimides. The SEM results reveal that the debris of GO are removed by the base washing of GO and the incorporated nanoparticles are well dispersed in the cured BMIM.

合成了结构上不同的双马来酰亚胺（BMI），例如4,4'-双马来酰亚胺二苯醚（BMIE），4,4'-双马来酰亚胺二苯砜（BMIS）和4,4'-双马来酰亚胺二苯甲烷（BMIM）。将石墨（G），氧化石墨烯（GO）和洗涤后的氧化石墨烯（WGO）颗粒分别与BMI混合（3％w / w），并在适当的条件下进行热聚合。使用差示扫描量热法（DSC）研究了纳米粒子在BMI中的存在的影响。DSC结果表明，混合的纳米颗粒改变了BMI的固化放热和固化焓。使用热重分析（TGA）了解固化的纯BMI及其与纳米颗粒的共混物的热稳定性。交联的BMIE基质中纳米颗粒的存在将热降解温度的开始转移到较高的温度区域（约15°C）。在所有研究的材料中，掺入BMIS的纳米颗粒会增加炭渣。这是由于物理分散的效率以及固化的双马来酰亚胺中纳米颗粒显示的可能的化学相互作用。SEM结果表明，GO的碱洗可除去GO的碎屑，并且掺入的纳米颗粒可以很好地分散在固化的BMIM中。这是由于物理分散的效率以及固化的双马来酰亚胺中纳米颗粒显示的可能的化学相互作用。SEM结果表明，GO的碱洗可除去GO的碎屑，并且掺入的纳米颗粒可以很好地分散在固化的BMIM中。这是由于物理分散的效率以及固化的双马来酰亚胺中纳米颗粒显示的可能的化学相互作用。SEM结果表明，GO的碱洗可除去GO的碎屑，并且掺入的纳米颗粒可以很好地分散在固化的BMIM中。
