“…Optical micrographs of the Pickering emulsions with different contents of CNT, and SEM images of the corresponding CNT/RC/ABS microparticles are shown in Figure 1. RC acted as both the stabilizer in Pickering emulsions via a combination of Pickering and networking mechanisms, 34 and a dispersant of CNTs. Well dispersed and stable emulsion droplets containing DCM/ABS oil surrounded by RC and CNT/RC were observed in the aqueous phase.…”

“…The polar hydroxyl groups of RC also enable the formation of strong intermolecular bonds with the polar cyanide (CN) groups of the AS component of ABS, 33 and also hydrogen bonds with CNTs 24 . Furthermore, RC has been successfully employed as a stabilizer in various studies involving the Pickering emulsion process for the preparation of nanocomposites 29,34 . Notably, Yu et al 30 successfully utilized cellulose nanocrystals to disperse and stabilize CNTs and PLA, respectively.…”

Lightweight polymer‐based conductive nanocomposites are attractive future electronic materials. However, the agglomeration of carbon nanotubes (CNTs) in the polymers is still a serious concern. Herein, CNTs were homogeneously dispersed in acrylonitrile–butadiene–styrene (ABS) matrix with the aid of regenerated cellulose (RC), via an easy and cost‐effective Pickering emulsion approach to form conductive nanocomposites. The prepared nanocomposites were investigated for their morphological, thermal, electrical, mechanical, and rheological properties. CNTs were observed to be uniformly entrapped within the RC suspension. RC proved to be both an efficient dispersant and stabilizer for CNTs and ABS, respectively, in that a noticeable enhancement in the electrical conductivity of the polymer of up to 21 Sm−1 was caused with the incorporation of 6.7 wt.% CNTs. RC alone caused 29.6% increase in the tensile strength of neat ABS, while the Young's modulus of the nanocomposites was increased by 21.1%. This improvement was attributed to the uniform dispersion of the stiff CNT/RC hybrid suspension and the formation of strong bond interactions in the ABS matrix. Furthermore, higher crystallinity and melt viscosity in the blends were achieved. This upturn in ABS properties will enable its wider application in the engineering industry as conductors, sensors, antistatic, and electromagnetic interference materials.

Polymer‐based hybrid materials have attracted great interest in academic research and industry because they can effectively combine the advantages of their different components. Pickering emulsions as designer platforms provide a very efficient and often unappreciated route to prepare polymer‐based hybrids. Their applications cover a broad range, including filter media, ion exchange modules, monolithic polymer supports for catalysis, covalent enzyme immobilization, and even scaffolds for tissue engineering. In this article, we first provide an introduction to the basics and formation of Pickering emulsions and then discuss how these systems can be used to obtain templates for the fabrication of materials with various morphologies, such as microspheres, fibers, films, and porous matrices. We then discuss the uniqueness of Pickering systems for morphology control and the resulting added value to obtain advanced complex and hybrid materials. We then review and summarize recent advances in the preparation approaches (polymerization and solvent evaporation) and physical morphologies (microspheres, fibers, films, and porous matrices). Finally, we offer an outlook for future developments.
