“…The gradual increase in electrical conductivity with the increasing MWNT-C amount in the films indicates a uniform distribution of nanotubes within the polymer matrix. Stacking or agglomeration of CNTs in a nanocomposite, especially at high CNT content, traditionally compromises its (nanocomposite) electrical conductivity. , Comparing our work to the literature over the past 15 years, ,,,− ,,− our electrical conductivity values lie in the highest conductivity range of CNT/polymer composites in general (Figure B) for 3.0 and 5.0 wt %, regardless of the polymer, CNT type, and nanocomposite preparation method. The highest electrical conductivity values reported in the literature are typically obtained based on conventional methods such as solution mixing and melt processing.…”

“…It was argued that the crystallinity of the polymer matrix did not affect the conductivity, while the higher conductivity values from the polymer nanocomposite with MWNT were likely caused by the intrinsic quality of MWNT as well as the intrinsic conductive nature of the commercially obtained iPP-g-MA. Li et al 42 studied the emulsion copolymerization of styrene/methyl methacrylate (MMA)/butyl acrylate (BA)/ acrylonitrile/acrylic acid to synthesize a styrene-acrylic copolymer, with hydroxylated MWNT (MWNT-OH) and carboxylated MWNT (MWNT-COOH) used separately as fillers. The MWNT-COOH/copolymer nanocomposite exhibited higher improvement in mechanical performance compared to MWNT-OH/copolymer.…”

“…Studies that utilize latex technology have shown remarkable enhancements in a wide range of different properties. − These studies have also reported promising improvement of CNT distribution in polymer latexes using different dispersion methods such as ultrasonication, functionalization, etc. Grossiord et al studied the effect of SWNT and MWNT on the electrical properties of amorphous and semicrystalline polymers: polystyrene (PS) and maleic anhydride-grafted isotactic polypropylene (iPP- g -MA), respectively.…”

Emulsion-based methods offer a range of advantages for fabrication of polymer nanocomposite materials. Herein, we have explored the use of in situ miniemulsion polymerization as well as a variety of physical mixing methods for preparation of nanocomposite films comprising multiwalled carbon nanotubes (MWNTs) and statistical copolymers based on styrene and n-butyl acrylate. Nanocomposite films were prepared at room temperature via simple drop casting of the obtained nanocomposite latex. It is demonstrated that both the fabrication method and compositional details such as the nature of the surfactant greatly influence the latex stability and the physical properties of the resulting nanocomposite films. Films prepared via miniemulsion polymerization exhibited high stretchability, whereas films produced by physical mixing showed electrical conductivities of approximately 10 2 S m −1 , which lies in the highest range reported to date for such materials via any preparation technique and is the highest ever for emulsion-based techniques within this concentration range of carbon nanotubes. The high electrical conductivity with tuneable mechanical properties shown in this study is envisaged to boost interest in polymer/CNT nanocomposites for different applications.

The utilization of bamboo resources can significantly alleviate the wood shortage and facilitate CO2 neutralization. However, the adhesive bonding performance of bamboo is not ideal, which greatly limits its application. Therefore, the biggest challenge is to explore a simple and effective method to enhance the bonding between bamboo and adhesive. In this study, we synthesized three butyl acrylate‐styrene (BS) emulsions with different monomer ratios and incorporated them into urea‐formaldehyde (UF) resins to prepare butyl acrylate‐styrene modified urea‐formaldehyde (BUF) adhesives. Results show that BS emulsion not only prolongs the workability time of UF adhesives (95 s–108 s), but also reduces the free formaldehyde content (0.38%–0.26%). Specifically, BS emulsion with the highest hard/soft monomer ratio makes BUF adhesive the lowest activation energy, showing the accelerated curing reaction. Specifically, the prepared laminated bamboo‐veneer lumber (LBVL) exhibits the best wet‐bonding strength and meets the Chinese National Standard, suggesting that BS emulsion with a higher hard/soft monomer ratio can enhance bonding performance. Thus, this efficient method can not only enhance various adhesive properties, but also improves the bonding performance on LVBL, which can greatly ease the shortage of wood resources and speed up the development of the bamboo industry.

Polymer nanocomposites are a class of composite materials containing polymer continuous phase as matrix and inorganic nanoparticles as fillers. Combining the advantages of both polymer and nanofillers, polymer nanocomposites can yield some desirable functionalities that cannot be achieved by the individual components, thus exhibiting tremendous potential for a variety of applications. However, their performances markedly depend on the dispersion and distribution of nanofillers in the polymer matrix. Recently, in situ emulsion polymerization has been demonstrated to be a powerful approach for the preparation of multifunctional polymer nanocomposites with good dispersion and homogeneous distribution of nanofillers. In this review, the fundamentals of polymer nanocomposites and their preparation strategies were briefly discussed, and then we comprehensively summarized recent advances in the design, preparation, functionalization and applications of polymer nanocomposites via in situ emulsion polymerization. The particular focus was placed on the strategies for achieving homogeneous and good dispersion of nanofillers within polymer matrixes. Moreover, the current challenges and future opportunities of in situ emulsion polymerization to polymer nanocomposites are discussed to motivate future contributions and explore new possibilities.This article is protected by copyright.
