“…Microcapsules with nanocellulose stabilized Pickering emulsions as templates are promising to encapsulate chemicals such as drugs for control release and phase change materials (PCMs) for thermal regulation. ,− PCMs can absorb or release abundant latent heat during phase change at an almost constant temperature. Therefore, PCMs are promising for thermal energy storage to address the mismatch of heat in space and time and have been extensively studied in energy-saving green building, thermal management of electronics, recovery of waste heat, and smart textiles. ,,,− However, organic PCMs suffer leakage issues, which severely limit their widely applications. Encapsulating PCMs into microcapsules with polymers as shells has been proven as an effective approach to prevent the leakage of PCM during usage and can also enhance the heat transfer due to increased interface between PCMs and matrices.…”

Nanocelluloses have attracted much attention in both academic and industrial fields. However, nanocelluloses, including cellulose nanocrystals and cellulose nanofibers, are generally produced by a “top-down” strategy with tedious violent chemical reactions and energy-intensive mechanical treatments. Fabrication of nanocellulose via facile and green approaches with a low cost is always challenging and promising. The digestion of grass by ruminants resembles the extraction processing of nanocelluloses from plants. Herein, lignocellulose nanoparticles (LCNPs) were extracted from cattle dung via facile filtration and centrifugation separation methods, indicating that LCNPs occurred naturally in cattle dung and were formed during digestion of grass. LCNPs are mainly composed of lignin, cellulose, and hemicellulose and possess an average diameter of ∼50 nm, high surface charge of −36.2 mV, and outstanding water dispersity. LCNPs show excellent Pickering emulsifying ability just as classic nanocellulose due to their partial wettability with both oil and water phases. LCNP stabilized Pickering emulsions were then employed as templates to prepare phase change material (PCM) microcapsules with melamine-formaldehyde shells to prevent leakage of PCM. The obtained PCM microcapsules display good thermal stability, durability, high PCM core content of 88.9% and phase change enthalpy of 214.3 J g–1, and are promising for thermal energy storage and temperature regulation applications. This study provides a sustainable approach to extract nanocellulose as Pickering emulsifier and will facilitate the high-value-added utilization of cattle dung.

“…Phase change materials (PCMs), substances that can store and release a large amount of heat via a phase change at a relatively constant temperature, have drawn considerable attention. PCMs have been used for heat storage in personal heat management, − energy-saving building, , solar energy storage, − infrared stealth, and electronic cooling. , PCMs should be form-stabilized or encapsulated to prevent leakage at the temperature over their melting points. Among them, encapsulation is promising, and based on their size, encapsulated PCMs can be classified into nano (below 1 μm), micro (between 1 and 1000 μm), and macro (over 1 mm) encapsulation .…”

Emulsion-templated, phase change material-encapsulated monolithic composites are advantageous for latent heat storage, but their infrared behavior and lack of stretchability hamper many more potential applications. Here, we report the fabrication of octadecane (OD)-encapsulated monolithic composites with flexibility and stretchability and their application for personal heat management for the first time. The composites were formed from interfacial cross-linking between isocyanate and poly(vinyl alcohol), which served as a monomer and an emulsion stabilizer. The composites showed flexibility over or slightly below the ambient temperature, robust compression (without leakage and fracture at 70% compressive strain), and high stretchability with tensile strain up to 30%. The heat storage and release temperatures were similar to that of OD, close to human body temperature, and the composites exhibited quite high heat density (up to 231.6 J g–1) and high reusability (without obvious decreases in heat density after 400 heating–cooling cycles). Moreover, the composites were verified effectively to decrease mean skin temperature and mean torso temperature of the human body, demonstrating to be a good candidate for personal heat management.
