Abstract

Highly electrically and thermally conducting films of expanded graphite/polymer nanocomposites were fabricated using an approach based on solution mixing methods. The use of Hydroxyethylcellulose and benzylic alcohol based solutions provides efficient dispersion and better exfoliation of multilayer graphene (nanographite) flakes that are further aligned in extended 2D layers forming continuous conductive pathways during lamination (hot calendering) process. Very high electrical conductivity (190 S/cm) was obtained for fabricated layered films. In contrast, for films produced by a conventional mixing and deposition method with acrylic copolymer and the same nanographitic material, with flakes randomly distributed within the composite, much lower conductivities (2.4 S/cm) were obtained.
基于膨胀石墨/聚合物纳米复合材料的柔性高导电薄膜
采用基于溶液混合方法的方法制备了膨胀石墨/聚合物纳米复合材料的高导电性和导热性薄膜。羟乙基纤维素和苄醇基溶液的使用提供了多层石墨烯(纳米石墨)薄片的有效分散和更好的剥离,这些薄片在层压(热压延)过程中进一步排列在延伸的2D层中形成连续的导电路径。对于所制造的层状膜,获得了非常高的电导率(190S/cm)。相反,对于通过丙烯酸共聚物和相同纳米石墨材料的常规混合和沉积方法制备的薄膜,其中薄片随机分布在复合材料内,获得了低得多的电导率(2.4S/cm)。
