“…The melted PCM shows weight loss and deformation, which cannot materialize a high TES ability [ 31 , 32 ]. In order to sustain an intrinsic TES capacity without any leakage, 3D porous graphene aerogel needs to fabricate a PCM composite with high form stability [ 33 , 34 ]. The PCM composite shows a high TES capacity to store or release thermal energy and can be connected to a thermoelectric power generator (PEG) for thermoelectric energy harvesting [ 35 ].…”

3D porous graphene aerogel exhibits a high surface area which can hold plenty of pure phase change material (PCM) into the internal space. In order to maintain the flexibility of PCM without volume shrinkage under the external force, cross-linked graphene aerogel was prepared by the cysteamine vapor method. The cross-linked graphene aerogel had a high stress–strain durability and chemical stability for infiltrating PCM to produce a form-stable PCM composite. The latent heat of PCM is one of the elements to estimate the capacity of PCM thermal energy storage (TES) during the phase transition process. The cross-linked graphene aerogel-supported PCM composite showed a great TES to be utilized in thermal-to-electrical energy harvesting. The cross-linked graphene aerogel also had an excellent mechanical property of preventing damage at a high temperature.

“…[100,101] Currently, the commercial thermoelectric module is the main component for thermoelectric conversion in energy generation systems associated with PCMs, and a stiff thermoelectric module without flexibility is used, even in heat-to-electrical energy conversion systems with thermally conductive materials. [102,103] In addition to thermoelectric modules, the integration of PCMs with solar cells (Figure 6b), [104] triboelectric nanogenerators (Figure 6c), [105] and pyroelectric energy harvesting systems (Figure 6d), [106] has been developed. Unlocking opportunities for more promising energy conversion systems, such as flexible thermoelectric modules for wearable products, ion-type thermoelectric generators for integrated heat collection devices, and solar steam generation for all-weather modes, remains an elusive goal.…”

As one of the main forms and intermediate carriers of energy, it is impressive to expand the application scope of heat energy, thereby boosting innovations in heat harvesting, conversion, storage, regulation, and utilization associated with the relevant techniques. Phase change materials (PCMs), as a state-of-the-art latent heat storage technique, have garnered increasing interest in heat-related applications over the past decades, and abundant high-performance PCMs with excellent shape stability and salient thermal conductivity have been developed. This review focuses on the issues concerning organic PCMs from the perspectives of flexible, multifunctional, and smart phase change composites, along with emerging applications and processing technologies, which are expected to offer possible guidance for the exploration of next-generation advanced functional phase change composites.

Integration of form-stable phase change material (PCM) composites with a pyro system can provide sufficient electrical energy during the light-on/off process. In this work, modified 3D porous graphene aerogel is utilized as a reliable supporting material to effectively reduce volume shrinkage during the infiltration process. Poly(vinylidene difluoride) (PVDF) is used for a transparent pyro film in the pyro system. The temperature fluctuation gives rise to a noise effect that restricts the generation of energy harvesting. The cross-linked graphene aerogel consisting of PCM composites can stabilize the temperature fluctuation in both melting and cooling processes. This shows that PCM composites can be applied to the pyro system under the change of the external environment. To evaluate the experimental results, a numerical simulation was conducted by using the finite element method (FEM).
