AbstractCellulose nanofiber (CNF) is a crystalline fiber composed of a bundle of cellulose molecular chains and is expected to be used as a new biomass-derived nanomaterial. The CNF has a unique morphology: a few to tens of nanometer width and a submicrometer to micrometer length. Its application to various materials, in particular its utilization as a polymer reinforcing material, has been anticipated due to its excellent mechanical properties. However, CNFs and plastics are generally hard to mix, and thus, it is difficult to combine them at the nanolevel. In this review, we describe the CNF/polymer nanocompositing process from Pickering emulsion. We use ~3 nm-wide wood-derived CNFs and report on the preparation of CNF/polymer homogenous composite films. We also introduce a new type of CNF/polymer composite, a core-shell microparticle, using this Pickering emulsion as a template.

To avoid conductive failure due to the cracks of the metal thin film under external loads for the wearable strain sensor, a stretchable metal/polymer composite film embedded with silver nanowires (AgNWs) was examined as a potential candidate. The combination of Ag film and AgNWs enabled the fabrication of a conductive film that was applied as a high sensitivity strain sensor, with gauge factors of 7.1 under the applied strain of 0–10% and 21.1 under the applied strain of 10–30%. Furthermore, the strain sensor was demonstrated to be highly reversible and remained stable after 1000 bending cycles. These results indicated that the AgNWs could act as elastic conductive bridges across cracks in the metal film to maintain high conductivity under tensile and bending loads. As such, the strain sensor engineered herein was successfully applied in the real-time detection and monitoring of large motions of joints and subtle motions of the mouth.

Comparative Review

Polymer composites have been identified as the most innovative and selective materials known in the 21st century. Presently, polymer concrete composites (PCC) made from industrial or agricultural waste are becoming more popular as the demand for high-strength concrete for various applications is increasing. Polymer concrete composites not only provide high strength properties but also provide specific characteristics, such as high durability, decreased drying shrinkage, reduced permeability, and chemical or heat resistance. This paper provides a detailed review of the utilization of polymer composites in the construction industry based on the circular economy model. This paper provides an updated and detailed report on the effects of polymer composites in concrete as supplementary cementitious materials and a comprehensive analysis of the existing literature on their utilization and the production of polymer composites. A detailed review of a variety of polymers, their qualities, performance, and classification, and various polymer composite production methods is given to select the best polymer composite materials for specific applications. PCCs have become a promising alternative for the reuse of waste materials due to their exceptional performance. Based on the findings of the studies evaluated, it can be concluded that more research is needed to provide a foundation for a regulatory structure for the acceptance of polymer composites.
