1. Introduction
Carbon nanohoops are hoop-shaped -conjugated molecules, in which paraphenylene units are linked in a cyclic manner [1]. Recently, the carbon nanohoops have been synthesized for applying in photo-, electro-, and photoelectronic fields because they are the simplest structural unit of armchair carbon nanotubes (CNTs)[2–4]. In fact, except functional properties, CNTs have been suggested ultra-high elastic modulus approaching 1 TPa, and exceptional tensile strengths in the range of 20–100 GPa [5,6]. CNT toughened materials can be achieved through crack deflection, crack bridging and CNT pull-out, for instance, in Al2O3 matrix [7]. Unfortunately, nanotube toughened thin films are yet to be realized due to diffi- culties in controlled alignment, interface reaction and reasonable volume fractions. Based on small volume, simple structure and similar properties, it is audaciously hypothesized that the films containing the carbon nanohoops will show a unique mechanical property. Although carbon nanohoops have a simple structure, their synthesis has been a significant challenge [8,9]. After extensive efforts,some chemical researchers have reported innovative synthetic routes to prepare carbon nanohoops [10,11]. However, in these cases, the synthesis of carbon nanohoops involves the use of organic reagents with phenyl (e.g. cyclohexadiene), which can eventually produce additional pollutants. The need for a synthesis route without organic reagents stimulates the ongoing research in this field. Titanium nitride (TiN) as a hard material is omnipresent in everyday life and plays a crucial role in multifarious engineering and functional applications. But the toughness and tribological behaviors of TiN hardly meet the demands of flexible devices and the micro-electro-mechanical systems [12]. Thus, in this work, we report the carbon nanohoops grown by CH4 plasma treatment at room temperature with free organic reagents. The carbon nanohoops that are employed as toughening and lubricant agents are filled into the porous TiN film and cover the film surface to obtain a composite multilayer film (named as CTF). Compared with individual TiN porous films (TF, its preparation and structure shown in Supporting information (SI)), CTF can perform quadruple effects: flexible, hard, lubricant and antiwear.
