1. Introduction
Carbon nanotubes (CNTs) are unique one-dimensional nanostructures with carbon atoms belonging to SP2 hybridization [1], and have good mechanical, electrical and thermal properties. For instance, theoretical and experimental results show that individual single-wall carbon nanotubes (SWCNT) have high tensile modulus (640 GPa to 1 TPa) [2] and tensile strengths (150e180 GPa) [3]. Past studies of CNT have gained great scientific and technological interest [4]. Recently, long, vertically aligned multi-walled nanotubes exhibited viscoelastic behavior and outstanding fatigue resistance under repeated high compressive strain [5,6]. A viscoelastic material composed of a random network of long interconnected carbon nanotubes was found to have an operational temperature range from 196 to 1000 C with thermal stability resulting from energy dissipation through the zipping and unzipping of carbon nanotubes at contacts [7]. Methods of mass production of CNTs increased over the past 20 years including several production lines with annual capacities of over several hundred tons of CNTs [8]. However, largescale industrial applications of CNT are still needed even though CNTs are commercially produced for lithium ion batteries [9], flexible touch screens [10], and CNT-based transistors [11], of which only 10 tons are used each year. Introducing CNT into polymer matrices to simultaneously enhance the mechanical properties and achieve new functional characteristics such as thermal and electrical conductivity, waveadsorbing, electric-magnetic shielding, is one promising direction for its application [12,13]. For instance, high performance elastomer composites with both high elasticity and conductivity have been successfully fabricated for the first time by using carbon nanotubesarray (CNTA) as nanosprings [14]. Meanwhile, the fabrication of graphene reinforced rubber tailored for tire has also been illustrated through the rational design of covalent interfaces [15]. and a simple, environment-friendly latex co-coagulation method [16]. A bio-based elastomer nanocomposites aimed for the application of tire is also reviewed [17]. In addition, Winey et al. [18] reviewed the effects of size, aspect ratio, loading, dispersion state and alignment of nanotubes within polymer matrices on the resulting mechanical, electrical, rheological, thermal and flammable properties. However, to overcome the difficulties of homogeneous dispersion of CNTs [19] and weak interfacial bonding between CNT and polymer matrices [20], researchers developed various approaches for improving dispersion, such as acid modifi- cation [21], ultrasonic dispersion [22], liquid compounding such as solution and latex compounding [23], in-situ polymerization [24] and melt compounding [25]. Most compounding methods are complicated and are cost-prohibitive, which hinders the large-scale industrial applications of CNT. Industries view melt compounding as the most environmentally friendly technique. However, the uniform dispersion of CNTs in polymer matrices is difficult in melt compounding because the synthesized CNTs are highly entangled. Our study designed and synthesized a new kind of CNT bundles that can be uniformly dispersed and have strong interfacial interactions.
