Recent Progress in PEG-Based Composite Phase Change Materials

Polymer Reviews, Год журнала: 2023, Номер 63(4), С. 1078 - 1129

Опубликована: Июнь 7, 2023

This review discusses advances in polyethylene glycol-based composite phase change materials (PCMs) for thermal energy storage (TES) and regulation. PCMs utilize latent heat storage, absorbing releasing during transitions within specific temperature ranges. Polyethylene glycol (PEG) is a promising organic PCM due to its easily tunable temperatures, high melting/freezing enthalpies, nontoxicity, among other advantages. However, PEG suffers from low conductivity requires encapsulation contain the flow of liquified PEG. To address these issues, has been composited with thermally conductive fillers porous materials. Moreover, modified have enhanced photothermal conversion efficiency, decreased supercooling, flame resistance. exemplary developments PEG-based PCMs, focusing on blending different polymers, doping various carbon (porous carbons, graphene, nanotubes), embedding into silica-based skeletons, synergizing hosts additives like layered doubled hydroxides, MXenes, metal-organic frameworks. work highlights key studies focused implementing building, pavement, electronic, textile, solar, waste recovery applications. The consequences synthesis parameters their effects PCM's transition properties are emphasized results.

Considering the increasing severity of electromagnetic wave pollution, development high-performance low-filler-content microwave absorbers possessing wide frequency bands and strong absorption for practical applications is a demanding research hotspot. In this study, from perspectives component coordination structural design, three-dimensional (3D) interconnected CoFe2O4/MXene-melamine foam (MF) was constructed via simple impregnation single freeze-drying step. By changing absorber (CoFe2O4/MXene) concentration, pore opening properties 3D foams can be effectively adjusted. When concentration sufficiently high to clog internal pores, hindered. filler (CoFe2O4/MXene-MF) content just ∼5.8 wt % (at density ∼33.3 mg cm–3), minimum reflection loss (RLmin) −72.1 dB achieved at matching thickness 3.32 mm, an effective bandwidth (4.54 GHz) covering whole X band 3 mm. CoFe2O4/MXene-MF, which possesses porous network structure, optimizes impedance enhances multiple polarization relaxations reflections/scattering, resulting in superior capabilities. particular, continuous structure ensures uniform distribution fields microstructure, achieving low contents. This work provides reference subsequent studies novel engineering strategy preparing low-filler-content, lightweight, efficient absorber, could applied radar security information communications.
