Abstract In this paper, a mixture of carbon nanotubes and amorphous carbon was pressed to fabricate a tablet-shaped structure of buckypaper. First, multi-walled carbon nanotubes were synthesized by the mechanothermal method. Subsequently, the multiwalled carbon nanotubes and ball-milled amorphous carbon were mixed. Then, they were put pressured to fabricate buckypaper. The results of Raman analysis of the produced buckypaper showed that the proposed method by forming a network of carbon nanotubes can be introduced as a novel way for the synthesizing of the buckypaper without any solvents. Scale-up fabrication, non-destruction of the structure of the nanotubes and subsequently maintaining the maximum quality of the carbon nanotubes, and flexibility of the process are the unique features of this approach.

1 Introduction Despite the diverse physical and chemical properties of carbon nanotubes, dimensions of carbon nanotubes severely restrict their applications [1]. Therefore, a continuous and interconnected network of carbon nanotubes has been developed in the macro-scale which is called buckypaper [2]. In the buckypaper, carbon nanotubes with van der Waals force are entangled together and form a uniform structure [3, 4]. High porosity (70–91%) [5, 6], high specific surface area (up to 2200 m2/g) [7], high bulk modulus (up to several GPa) [8], chemical and thermal stability [3], and high electrical conductivity [9] are the most important properties of the buckypaper. Due to this wide range of properties, applications of buckypaper are on the rise. Some of these applications in various technologies include use in insulations [10], field emission displays [11], lithium batteries [12], filters [13–15], adsorption applications [16], supercapacitors [17], electrodes [18], strain sensing [19] and sensors [20], transistors [21],

actuators [22], biological applications and drug delivery [23–25], and composite materials [26]. Nowadays, the methods for synthesizing the buckypaper are divided into wet and dry ways [3]. The filtration approach, as a wet method, was the first synthesis of buckypaper by Smalley et al. in 1998 [2] and is still recognized as the main method for the production of the buckypaper [3]. Generally, wet methods are performed by creating a solution of carbon nanotubes, then functionalized, filtrated, and dried [27–29], or generated by aligning the carbon nanotubes through a water pressure [3]. Dry methods include chemical vapor deposition (CVD) [30] and other different methods ba
