“…Graphene has been demonstrated to have ultrahigh thermal conductivity [46,55,56]. Baladin et al measured the thermal conductivity of a graphene monolayer and found that it exceeded 3000 W/m·K near room temperature via optothermal Raman measurement [57,58].…”

Thermal management in microelectronic devices has become a crucial issue as the devices are more and more integrated into micro-devices. Recently, free-standing graphene films (GFs) with outstanding thermal conductivity, superb mechanical strength, and low bulk density, have been regarded as promising materials for heat dissipation and for use as thermal interfacial materials in microelectronic devices. Recent studies on free-standing GFs obtained via various approaches are reviewed here. Special attention is paid to their synthesis method, thermal conductivity, and potential applications. In addition, the most important factors that affect the thermal conductivity are outlined and discussed. The scope is to provide a clear overview that researchers can adopt when fabricating GFs with improved thermal conductivity and a large area for industrial applications.

“…Subsequently, the samples were hung for 10 h in an oven at 60°C. The similar experimental method was also described by our previous published literatures . The obtained PCCFMs were recorded as CA–PA–SA/PAN, CA–PA–SA/PAN/MWNTs‐COOH5, CA–PA–SA/PAN/MWNTs‐COOH10, and CA–PA–SA/PAN/MWNTs‐COOH20, respectively.…”

“…Optional supporting materials included many polymers (e.g., polyethylene terephthalate , polypyrrole , and linear low‐density polyethylene ) and inorganic materials (e.g., expanded perlite , silicon dioxide , palygorskite , titanium dioxide ) for the preparation of form‐stable PCMs. Moreover, a great deal of high thermal conductive fillers such as graphene , metal oxide particles , expanded graphite , metal particles , carbon nanotubes , carbon nanofibers , and graphene oxide were used to enhance the total heat transfer rates of PCMs. Among the above materials, carbon nanotubes as a kind of one‐dimensional nanostructured materials have been employed as suitable high thermal conductive filler to increase the heat transfer rates of PCMs.…”

A series of novel capric–palmitic–stearic acid ternary eutectic/polyacrylonitrile/carboxyl purified multi‐walled carbon nanotubes (CA–PA–SA/PAN/MWNTs‐COOH) form‐stable phase change composite fibrous membranes (PCCFMs) were fabricated by electrospinning and physical absorption methods. In these form‐stable PCCFMs, the CA–PA–SA ternary eutectic was served as phase change material for thermal energy storage, and the loaded MWNTs‐COOH was acted as thermal conductivity enhancement filler to improve heat transfer rates, as well as electrospun PAN/MWNTs‐COOH fibrous membranes with different weight fractions of MWNTs‐COOH (i.e., 5, 10, and 20 wt%) were used as supporting materials to provide structural strength and prevent liquid leakage of melted CA–PA–SA ternary eutectic. The morphological structure and thermal performances were investigated and analyzed. The images of scanning electron microscopy showed that the CA–PA–SA ternary eutectic was uniformly embedded and dispersed into the three‐dimensional porous network structure of electrospun PAN/MWNTs‐COOH fibrous membranes. Thermal performance tests suggested that the melting and freezing times of the CA–PA–SA/PAN/MWNTs‐COOH form‐stable PCCFMs with the addition of 10 wt% MWNTs‐COOH were significantly shorten by about 52% and 56% in comparison with those of the CA–PA–SA/PAN form‐stable PCCFMs. Their phase change temperatures and enthalpies were about 7°C–32°C and 130–138 kJ/kg, respectively.

“…Currently, lots of research has been focused on the potential applications of rGO-based aerogels in energy storage systems (i.e., Li batteries [8–11], supercapacitors [12–16]), sensors (gas sensors [17–19], biosensors [20–21]) and adsorbers (oil pollution [22–23], organic contaminants [24–25]). Moreover, the properties of GO-based aerogels can be modified by addition of various functional additives, e.g., nanoparticles or polymers [26–29]. As produced hybrid aerogels are featured by unique properties with wide area of new and interesting potential applications [30–32].…”

Reduced graphene oxide–magnetite hybrid aerogels attract great interest thanks to their potential applications, e.g., as magnetic actuators. However, the tendency of magnetite particles to migrate within the matrix and, ultimately, escape from the aerogel structure, remains a technological challenge. In this article we show that coating magnetite particles with polydopamine anchors them on graphene oxide defects, immobilizing the particles in the matrix and, at the same time, improving the aerogel structure. Polydopamine coating does not affect the magnetic properties of magnetite particles, making the fabricated materials promising for industrial applications.
