“…As is known, the thermal conductivity is positively correlated with the rate at which PCMs store and release energy, reflecting the sensitivity of the thermal response of PCMs . In this study, the thermal conductivity of HDA- g -GN was as high as 3.957 W/(m K), which is much higher than that of HDA (about 0.20 W/(m K)) and that of most reported results, ,,− as seen in Figure f. The relevant data on the heat conduction of HDA- g -GN are listed in Table S4.…”

A phase change material (PCM) essentially making up hexadecyl acrylate-grafted graphene (HDA-g-GN) was fabricated via a solvent-free Diels–Alder (DA) reaction. The novel material exhibits multiresponsive, enhanced thermal and electrical conductivities and valid thermal enthalpy. In addition, the optimum DA reaction conditions were explored. A variety of characterization techniques were used to study the thermal, crystalline, and structural properties of HDA-g-GN. The melting and crystallizing enthalpies of HDA-g-GN were as high as 57 and 55 J/g, respectively. Furthermore, the melting and freezing points of HDA-g-GN were 29.5 and 32.7 °C, respectively. The thermal conductivity of HDA-g-GN reached 3.957 W/(m K), which is well above that of HDA itself and the previously reported PCMs. HDA-g-GN exhibited an excellent electric conductivity of 219 S/m. Compared to HDA, the crystalline activation energy of HDA-g-GN decreased from 397 to 278 kJ/mol (Kissinger model) and 373 to 259 kJ/mol (Ozawa model). Moreover, HDA-g-GN exhibited excellent thermal stability, shape stability, and thermal reliability. More importantly, HDA-g-GN can be employed to realize high-performance light-to-thermal and electron-to-thermal energy conversion and storage, which provides wide application prospects in energy-saving buildings, battery thermal management system, bioimaging, biomedical devices, as well as real-time and time-resolved applications.

“…Each carbon atom is attached to three other carbon atoms by covalent bonds, and layers are held together by van der Waals forces (Chen et al 2019). It has many advantages, such as high-temperature resistance, small thermal expansion coefficient, lubricity, plasticity, chemical stability, electrical conductivity, and antistatic wire (Hokao et al 2000;Park et al 2015;Huang et al 2016;Ramanujam et al 2017).

Activated carbon, graphite, and GO/gelatin composite films were prepared by the blending method. The properties of composites were characterized by tensile strength (TS), elongation at break (EB), water vapour permeability (WVP), water-absorption ability, contact angle, scanning electron microscopy (SEM), and moisture at different temperatures. The properties of GO/gelatin composite films were better when each of three kinds of carbon materials were used as reinforcement phases and added into the matrix gelatin. The results showed that EB and TS of GO/gelatin composite films were both excellent. The moisture of GO/gelatin composite films was greater than the others. SEM micrographs showed that GO had better compatibility and dispersibility with gelatin than activated carbon and graphite. The water absorption of GO/gelatin composite films were low, at 15 °C and 25 °C, and the WVP was low at 35 °C. The WVP of GO/gelatin composite films was lower than the others at different temperatures. The contact angle of GO/gelatin composite films was larger than the others.

Preparation and characterization of graphite/thermosetting composites

Graphite/thermosetting composites were prepared via a melt blending and compression-curing process using epoxy and phenolic resins as polymer matrices. The flexural strength, flexural modulus and electrical conductivity of the composites were investigated. The composites containing 55 wt% graphite showed the maximum flexural strength and modulus. Scanning electron microscopy results showed that the thermosetting resins and graphite were uniformly dispersed on the fractured surface of the composites. The electrical conductivity of the composites increased with an increase in the graphite content. The flexural and electrical properties of the composites improved significantly by the addition of a carbon fibre cloth (CFC) or a CFC and carbon nanotubes.
