We present the critical and systematic investigations on the normal/regular types of carbon black to trigger the conductivity of polymer nanocomposite in developing commercially viable coated flexible fabric. Regular grade carbon blacks are utilized to develop conductive fabric via nanocomposite preparation and application by knife-over-roll coating (average 90 microns thick). The study suggests, tailored secondary microstructure of carbon black particles having a diameter of 30 nanometers (with ∼0.6 packing fraction, 5.815E + 19 per cc charge carrier density, 0.774 ratios of Hall coefficient) has a profound effect on conductivity. The microstructure of carbon black is altered by the shearing force of a mechanical stirrer in a viscous solution of natural rubber latex and polyvinyl alcohol then self-restructured when an excess amount of water is evaporated by high-temperature drying. Thus, the tailored secondary microstructure of carbon black with a diameter of 30 nanometers provides the highest charge carrier density as compared to other types of carbon black used. We found that the attained conductivity (>113 S/m) in this process is 98% of the predicted value as per the classical model. This technique can be exploited to use normal grade carbon black in replacement of conductive grade carbon black and other carbonaceous material like graphene and carbon nanotube. We envision that this easily scalable, commercially viable technique can be utilized for large scale production of conductive fabric.

我们提出了对炭黑的正常/常规类型进行批判和系统的研究，以触发开发商业上可行的涂层柔性织物时聚合物纳米复合材料的电导率。常规级炭黑用于通过纳米复合材料制备和通过辊涂刮涂（平均90微米厚）进行涂覆来开发导电织物。研究表明，量身定制的直径为30纳米的炭黑颗粒的二级微观结构（填充率为0.6，每立方厘米电荷载流子密度为5.815E + 19，霍尔系数为0.774）对电导率具有深远的影响。在天然橡胶胶乳和聚乙烯醇的粘稠溶液中，机械搅拌器的剪切力会改变炭黑的微观结构，然后在高温干燥过程中蒸发掉过量的水时，该炭黑会自动重整。因此，与使用的其他类型的炭黑相比，直径为30纳米的炭黑的定制二级微观结构可提供最高的载流子密度。我们发现，根据经典模型，在此过程中获得的电导率（> 113 S / m）是预测值的98％。可以利用该技术来使用普通级炭黑来代替导电级炭黑和其他碳质材料，例如石墨烯和碳纳米管。我们设想这种易于扩展的方式，
