“…[ 3–6 ] NF based composites find applications in the automobile industry, as conducting composites, in barrier applications, drug delivery systems, building, and construction industry. [ 7–9 ] However, they have not been considered significantly to be utilized in electronic devices, such as strain sensors, batteries, supercapacitors, and other electronic devices, [ 10 ] which would add high‐value in terms of cost reduction. In order to do so, these fibers have to be electrically conductive with the use of conductive materials and fillers.…”

This study focuses on the development of strain‐sensors utilizing biodegradable natural fabrics (cotton, flax, and wool) and graphene nanoplatelets (GN) through novel coating techniques. A systematic study on improving the electrical conductivity of natural fiber fabrics to be used as effecting sensing stimuli was conducted by varying the proportions of graphene. To further enhance the conductivity, GN was hybridized with conducting polymers, such as polypyrrole (PPy), polyaniline (PANI), and with carbon black (CB). The electrical conductivity, morphological, and mechanical characterizations were carried composites for detailed comparative analysis. The conductive composites were incorporated into flexible and stretchable silicone elastomer (Ecoflex) to be used as strain sensors. Electromechanical characterizations were carried out on the composite sensors and their performance on different human body motions, including finger, wrist, elbow, and knee movements were assessed. The results showed that the addition of hybrids, such as PPy increased the electrical conductivity in fabrics (for instance, cotton with a conductivity of 1.7 S.cm−1). However, the addition of PANI tends to have a negative effect on the conductivity due to poor ability to deposit on the fiber surface. It was observed that the thermal stability was improved with the addition of conductive particles which gives rise to excellent sensitivity and durability of the composite sensors.

“…Therefore, it is necessary to study the heat transfer during boiling in various modes (nucleate and bubble growth, transition, and film), as well as critical heat fluxes on superhydrophobic surfaces of graphene nanocomposites. The topic of studying graphene nanocomposites as heat transfer, evaporation, boiling, and condensation surfaces is an important and relative new direction, which should be given great attention in the future [20][21][22][23][24][25][26][27].…”

Most existing materials may not satisfy all the fundamental requirements of modern civilization. This chapter summarizes the latest advances in the study of hybrid graphene nanocomposites and their application as thermal interface materials and some functional energy materials, in particular, for thermal management of energy and electronic devices. The main properties of hybrid graphene nanocomposites are described. The main attention is paid to the thermal properties of such materials, in particular, thermal conductivity and the possibilities of its growth due to various changes in the morphology and other properties of nanocomposites. The technology of obtaining a new nanocomposite based on mesoscopic microspheres, polymers, and graphene flakes is considered.
