Thermal steadiness and flame-resistant characteristics of PP/GO nanocomposites were explored. Inclusion of graphene oxide nanosheets (GOs) increased thermal steadiness of the nanocomposites by at least 50 °C through nano-confinement of PP connections and restriction of release of gaseous molecules during degradation. Pyrolysis showed that process of the degradation of PP was not changed in the presence of nanofillers and alkenes consisting of carbon particles that were deterioration products. With addition of GOs to PP, cone calorimetry experiments exposed a substantial deviation in ignition under irradiation. In addition, inclusion of GOs reduced PP's rate of combustion owing to the creation of a carbon shielding sheet acting as the heat and mass transfer barrier. Uniformly dispersed GOs shifted the decomposing onset temperature (T_onset) of PP to around 40 °C higher which induced a great melt flow rate in the composites and dramatically changed their fire behavior. Delayed dripping resulted in considerably enhanced heat absorption and reduced time for ignition. As a result of development of a shielding film in combustion, under flaming conditions, the highest thermal discharge level of 78% was accomplished. The most prominent features that made PP to prefer carbon nanoparticles were demonstrated by the well-exfoliated GO nanosheets in the PP matrix which was evidenced by TEM images. Findings of TGA indicated that the GO's addition enhanced the thermal steadiness and PP's char yields. The nanocomposites of PP/GO 5.0 wt% attained UL-94 with a grade of no dripping and grade V-1. Cone calorimeter test results showed that the PP's burning performance, peak heat release rate (PHRR) and average specific extinction area decreased noticeably when the GOs' combination effects was intervened. PHRR showed a decrease of 46% compared to the neat PP for the PP/GO 5.0 wt% nanocomposite. This role offered a new modified approach to enhance the GO's flame-resistant effectiveness.

探讨了PP / GO纳米复合材料的热稳定性和阻燃特性。包括氧化石墨烯纳米片（GOs），通过PP连接的纳米限制和降解过程中气体分子的释放限制，可将纳米复合材料的热稳定性提高至少50°C。热解表明，在纳米填料和由碳颗粒（其为降解产物）组成的烯烃的存在下，PP的降解过程没有改变。在PP中加入GOs后，锥形量热法实验暴露了辐照下点火的明显偏差。此外，由于创建了碳屏蔽片，作为传热​​和传质的屏障，GO的加入降低了PP的燃烧速率。均匀分散的GO改变了分解起始温度（Ť_发PP）升高到40°C左右，这在复合物中引起了很大的熔体流动速率，并极大地改变了它们的着火性能。延迟滴落会大大提高吸热率并缩短点火时间。由于燃烧过程中形成了屏蔽膜，因此在燃烧条件下，可以达到78％的最高散热水平。TEM图像证明，PP基质中的GO纳米片充分剥落，证明了PP首选碳纳米颗粒的最显着特征。TGA的发现表明，GO的加入提高了热稳定性和PP的炭收率。PP / GO 5.0 wt％的纳米复合材料达到UL-94等级，无滴落，等级V-1。锥形量热仪测试结果表明，PP的燃烧性能，当GOs的组合效应被干预时，峰值放热率（PHRR）和平均比消光面积显着降低。对于PP / GO 5.0 wt％纳米复合材料，PHRR与纯PP相比下降了46％。该角色提供了一种新的改进方法，以增强GO的阻燃效果。
