论文摘要
聚二甲基硅氧烷（PDMS）是一种绝缘子，通常用于制造微型结构，但需要电导性PDMS。因此，这项研究主要集中于产生具有高电导率的PDMS纳米复合材料。因此，我们生产了高度导电的PDMS纳米复合材料，其中填充了多壁碳纳米管（MWCNT）和石墨烯纳米纤维素（GNP）。由于聚合物基质内的CNT和GNP之间的协同作用，我们希望比仅填充CNT的PDMS纳米复合材料获得更多的导电纳米复合材料。此外，我们研究了硫酸处理对制备的PDMS/MWCNT/GNP纳米复合材料的表面组成和电导率的影响。结果表明，经硫酸处理的样品的电导率显着高于未经处理的样品。获得了270.7至1074.9 s/m的电导率水平，较高的电导率是用酸溶液处理的样品。
Polydimethylsiloxane (PDMS) is an insulator and it is commonly used in fabrication of micro-structures but there is a need of electrical conductive PDMS. Therefore, this research is mainly focused on producing PDMS nanocomposites with high electrical conductivity. Thus, we produced highly conductive PDMS nanocomposites which were filled with multiwalled carbon nanotubes (MWCNTs) and graphene nanoplatelets (GNPs). Due to the synergistic effect between CNTs and GNPs inside a polymeric matrix, we expected to obtain more conductive nanocomposites than PDMS nanocomposite filled with only CNTs. Additionally, we investigated the effect of sulfuric acid treatment to surface composition and electrical conductivity of prepared PDMS/MWCNT/GNP nanocomposites. Results indicated that electrical conductivity of sulfuric acid-treated samples was significantly higher than untreated samples. The level of conductivity in the range of from 270.7 to 1074.9 S/m was obtained, and the higher ones are the samples treated with acid solution.
