In this study, we have investigated and compared electrical, optical, and mechanical properties of polystyrene thin films with added multi-walled carbon nanotube and carbon mesoporous. Surface conductivity (σ), scattered light intensity (I sc ), and all the mechanical parameters of these composites have increased with increasing the content of carbon filler (multi-walled carbon nanotube or carbon mesoporous) in the polystyrene composites. This behavior in electrical, mechanical, and optical properties of the polystyrene/carbon fiber composites has been explained by classical and site percolation theory, respectively. The electrical percolation thresholds (R σ ) were determined to be 8.0 wt% for polystyrene/multi-walled carbon nanotube and 25.0 wt% for polystyrene/carbon mesoporous composites. The optical percolation thresholds were found to be R op = 0.8 wt.% for polystyrene/multi-walled carbon nanotube and R op = 3.0 wt.% for polystyrene/carbon mesoporous composites. For the polystyrene/carbon mesoporous composite system, it was determined that the mechanical percolation threshold occurred at lower R values than the polystyrene/multi-walled carbon nanotube composite system. The electrical (β σ ), optical (β op ), and mechanical (β m ) critical exponents have been calculated for both of the polystyrene/carbon fiber composites and obtained as compatible with used percolation theory.

多壁碳纳米管和碳介孔掺杂聚苯乙烯复合材料的电学、光学和机械渗透

在这项研究中，我们研究并比较了添加多壁碳纳米管和碳介孔的聚苯乙烯薄膜的电学、光学和机械性能。随着聚苯乙烯复合材料中碳填料（多壁碳纳米管或碳​​介孔）含量的增加，这些复合材料的表面电导率（σ）、散射光强度（I sc ）和所有机械参数都增加。聚苯乙烯/碳纤维复合材料在电学、机械和光学性能方面的这种行为已分别由经典和现场渗透理论解释。聚苯乙烯/多壁碳纳米管的电渗透阈值 (R σ ) 确定为 8.0 wt%，聚苯乙烯/碳介孔复合材料为 25.0 wt%。发现聚苯乙烯/多壁碳纳米管的光学渗透阈值为 R op = 0.8 wt.%，聚苯乙烯/碳中孔复合材料的 R op = 3.0 wt.%。对于聚苯乙烯/碳介孔复合系统，确定机械渗透阈值发生在比聚苯乙烯/多壁碳纳米管复合系统更低的 R 值下。已经计算了两种聚苯乙烯/碳纤维复合材料的电学 (β σ )、光学 (β op ) 和机械 (β m ) 临界指数，并与所使用的渗透理论相容。确定机械渗透阈值发生在比聚苯乙烯/多壁碳纳米管复合系统低的 R 值下。已经计算了两种聚苯乙烯/碳纤维复合材料的电学 (β σ )、光学 (β op ) 和机械 (β m ) 临界指数，并与所使用的渗透理论相容。确定机械渗透阈值发生在比聚苯乙烯/多壁碳纳米管复合系统低的 R 值下。已经计算了两种聚苯乙烯/碳纤维复合材料的电学 (β σ )、光学 (β op ) 和机械 (β m ) 临界指数，并与所使用的渗透理论相容。
