Multiscale Porous Architecture Consisting of Graphene Aerogels and Metastructures Enabling Robust Thermal and Mechanical Functionalities of Phase Change Materials

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: May 13, 2024

Abstract Passive thermal energy storage systems using phase change materials (PCMs) are promising for resolving temporal‐spatial overheating issues from small‐ to large‐scale platforms, yet their poor shape stability due solid–liquid transition incurs PCM leakage and weak resistance against mechanical disturbance, limiting practical applications. While foam‐stable templates PCMs have shown complement, they reveal massive collapse of liquefied under external loads or impacts. Herein, a multiscale porous architecture consisting graphene aerogels (GAs) meta structures enabling robust thermal‐mechanical functionalities (3D‐MPGA) toward sustainable composites is reported. 3D‐printed metamaterials employing octet‐truss cells provide supportive strength directionally‐assisted reduction, while GAs serve as with surface‐interfacial contacts, thereby fixing paraffin wax inside nano/micropores. The 3D‐MPGA shows intrinsic characteristics bulk PCMs, improved thermal‐mechanical‐chemical stability, confirmed by long‐term heating‐cooling cycle tests over 10 h. Moreover, it exhibits highly reinforced (200–5000%) within low density across ambient melting temperatures, maintains original shapes in the without severe leakage, loads. This work inspires rational strategies advancing PCM‐based systems.

Abstract Thermal management is a key link in improving energy utilization and preparing insulation materials with excellent performance the core technological issue. Complex irregular pore structures of hinder exploration structure‐property relationships further promotion material performance. Ordered mesoporous silica (OMS) kind porous ordered frameworks. This work elucidates effects architecture on thermal conductivity silica. Herein, two typical OMS, SBA‐15 SBA‐16, characterized by well‐defined distinct spatial orientations are synthesized to study relevance between structure conductivity. Compared 3D cubic 2D hexagonal exhibits anisotropic that restrict both solid gaseous conduction, thereby providing better insulating. Due influence porosity, found decrease strongly increasing size decreasing wall thickness. Moreover, OMS composite aerogels outstanding insulation, mechanical performance, hydrophobicity fabricated through incorporating into cellulose nanofibers (CNF). Consequently, this contributes deeper understanding heat transfer provides an idea for designing OMS‐based materials, advancing their potential applications.

Can Adhesion Energy Optimize Interface Thermal Resistance at a Soft/Hard Material Interface?

Nano Letters, Journal Year: 2023, Volume and Issue: 23(14), P. 6673 - 6680

Published: July 10, 2023

Thermal resistance at a soft/hard material interface plays an undisputed role in the development of electronic packaging, sensors, and medicine. Adhesion energy phonon spectra match are two crucial parameters determining interfacial thermal (ITR), but it is difficult to simultaneously achieve these one system reduce ITR interface. Here, we report design elastomer composite consisting polyurethane-thioctic acid copolymer microscale spherical aluminum, which exhibits both high adhesion (>1000 J/m2) with hard materials, thus leading low 0.03 mm2·K/W. We further develop quantitative physically based model connecting ITR, revealing key plays. This work serves engineer from aspect energy, will prompt paradigm shift science.
