1. Introduction
The unique chemical structure and high aspect ratios of carbon nanomaterials (CNMs), such as carbon nanotubes (CNTs), can enhance the overall performance of polymer/CNMs composites. It has attracted tremendous attention due to their excellent mechanical, electrical, and thermal characteristics [1e4] and has been developed for applications such as sensors [5], stretchable conductors [6], shape memory materials [7], and oil/water separation [8]. The key issue of conductivity is the formation of percolation networks of CNTs in polymer matrix, which is essential to construct conductive path through the composite [9]. The morphological studies verified that CNTs can be triggered to form conductive network under engineered processing conditions, such as polymer blends [10], shear forces [11], latex particle [12], electric field [13], nanoimprint lithography [14], and preformed scaffold [15]. However, unless the interface between nanotubes and polymer is carefully modified, the agglomeration of CNTs may inevitably occur due to their intrinsic poor dispersibility and processability, and lead to deterioration and fluctuations in properties [16]. Therefore, under most conditions, surface modification of CNTs has become an essential step for its applications [17]. Covalent functionalization and non-covalent wrapping are generally adopted methods [18e20]. It is important to emphasize that, although a well surface modification indeed improve the stability and dispersity of CNTs in solvent or polymer matrix, it is not in favor of the formation of percolation networks because the polymers or surfactants fully covered on the CNTs surface may prevent the interconnection of CNTs, (Fig. 1). Up to now, it is still a great challenge to construct conductive percolation networks in polymer/CNTs composites with high efficiency through a facile and wide applicable strategy. In this work, we demonstrate a novel sparsely partial wrapping * Corresponding author. strategy for constructing percolation networks in this article. As
