In the earlier studies carbon nanomaterials were synthesized by using cheaper raw materials such as coal, super clean coal, plastics etc. by the authors research group. Presently, carbon nanomaterials such as graphene and carbon nanotubes have been prepared from cheap carbon-based materials such as dry ice and Pongamia oil. The graphene and carbon nanotubes were also synthesized by catalytic reduction of carbon dioxide (dry ice) in the presence of magnesium metal flame and from pongamia oil using chemical vapour deposition setup respectively. The multiwalled carbon nanotubes (MWCNTs) were synthesized. The synthesized graphene and MWCNTs were characterized by different characterization techniques such as scanning electron microscopy, transmission electron microscopy. Thus, synthesized graphene and MWCNTs have been used as conductive filler in polycarbonate/ethylene methyl acrylate nanocomposites. Different properties i.e. electrical conductivity and electromagnetic inference shielding properties of these nanocomposites have been studied. This study opens new avenues for the fabrication of novel lightweight materials that may be used in communication systems or for other applications such as in the fuel cells, solar cells, supercapacitors, Lithium ion batteries. Several cheaper raw materials have been suggested for the production of CNTs, graphene, carbon nanoparticles, quantum dots etc.

使用低成本碳基原料生产石墨烯和碳纳米管，并将其用于生产聚碳酸酯/乙烯丙烯酸甲酯甲基纳米复合材料

在较早的研究中，作者研究小组使用煤，超洁净煤，塑料等较便宜的原料合成了碳纳米材料。目前，碳纳米材料例如石墨烯和碳纳米管已经由廉价的碳基材料例如干冰和Pongamia油制备。石墨烯和碳纳米管还分别通过在镁金属火焰存在下通过催化还原二氧化碳（干冰）和使用化学气相沉积装置从浮游生物油中合成而来。合成了多壁碳纳米管（MWCNT）。通过不同的表征技术，如扫描电子显微镜，透射电子显微镜，对合成的石墨烯和多壁碳纳米管进行了表征。因此，合成的石墨烯和MWCNTs已被用作聚碳酸酯/乙烯丙烯酸甲酯甲基纳米复合材料的导电填料。已经研究了这些纳米复合材料的不同性质，即电导率和电磁干扰屏蔽性质。这项研究为制造新型轻质材料开辟了新途径，这些轻质材料可用于通信系统或其他应用，例如燃料电池，太阳能电池，超级电容器，锂离子电池。已经提出了几种较便宜的原材料用于生产CNT，石墨烯，碳纳米颗粒，量子点等。这项研究为制造新型轻质材料开辟了新途径，这些轻质材料可用于通信系统或其他应用，例如燃料电池，太阳能电池，超级电容器，锂离子电池。已经提出了几种较便宜的原材料用于生产CNT，石墨烯，碳纳米颗粒，量子点等。这项研究为制造新型轻质材料开辟了新途径，这些轻质材料可用于通信系统或其他应用，例如燃料电池，太阳能电池，超级电容器，锂离子电池。已经提出了几种较便宜的原材料用于生产CNT，石墨烯，碳纳米颗粒，量子点等。
