Improving the thermal energy storage capability of diatom-based biomass/polyethylene glycol composites phase change materials by artificial culture methods

On the diatomite-based nanostructure-preserving material synthesis for energy applications

“…Here, Dm denotes microwave-acid treated diatomite while D denotes raw diatomite. Konuklu et al 88 also reported improvement in storage capacity after modifying diatomite by subjecting the diatomite to microwave radiations in a home-style microwave at 700 W. A recent work by Huang et al 196 which used an artificial culture method to generate PEG/diatomite composites exhibited high latent heat values. For the melting and crystallization processes, 121.54 J g −1 and 127.20 J g −1 were respectively obtained for the latent storage of PEG/sintered-diatom composite with an improved enthalpy efficiency of about 98.1%.…”

Crystallization induced realignment of carbon fibers in a phase change material to achieve exceptional thermal transportation properties

“…17 To prevent PCM leaks, researchers have developed compensating technologies, including microencapsulation, employing porous materials and nanostructures, and embedding PCMs in a polymer matrix. 20–31 Wang et al introduced hybrid shell microencapsulation to construct a composite with good thermal energy storage-release performance. 32 Using polyacrylic acid (PAA) and poly(oxy-1,2-ethanediyl) (PEG), Zhao et al synthesized a mechanically transformative dynamic gel.…”

Phase Change Material (PCM) Composite Supported by 3D Cross-Linked Porous Graphene Aerogel

“…Long-term temperature variation leads to usable pyro-to-electrical conversion to provide large external energy. To achieve thermal energy accumulation, phase change materials (PCMs) are normally used due to their high latent heat and thermal properties [7,8]. Multiple PCMs have been introduced to make a recyclable thermoelectric energy harvesting system that can generate electrical energy during the phase transition process [9,10].…”
