Lignocellulose Nanoparticles Extracted from Cattle Dung as Pickering Emulsifiers for Microencapsulating Phase Change Materials

“…PCM microcapsules can effectively prevent the leakage of PCM and enhance the interface of PCM with matrices and have been well studied in the fields of energy-saving building, battery thermal management, and smart textiles. ,,, Pickering emulsion provides a facile and sustainable approach to fabricating PCM microcapsules. LCNP stabilized C 22 –Pickering emulsions with docosane (C 22 ) as PCM were employed as templates to prepare C 22 -microcapsules.…”

“…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.…”

Flexible composite phase change materials with enhanced thermal conductivity and mechanical performance for thermal management

“…In recent years, organic solid-liquid phase change materials (PCMs) have been widely studied in thermal management systems owing to their high latent heat storage capacity and stable physicochemical properties. [6][7][8][9] However, the low intrinsic thermal conductivity and leakage in the molten state of organic solid-liquid PCMs greatly limit their practical applications in thermal management. [10][11][12][13][14][15] Although great efforts have been made to improve the thermal conductivity and shape stability of organic solid-liquid PCMs by introducing a variety of supporting and thermally conductive reinforcements, there are still some problems to be further solved in the practical applications of these high-performance composite PCMs.…”

Efficient and Secure Encapsulation of a Natural Phase Change Material in Nanofibers Using Coaxial Electrospinning for Sustainable Thermal Energy Storage

“…Further, the nanofiber PCMs achieved much higher PCM loadings than other form-stable PCMs, such as nanocapsules and microcapsules . Thanks to their large surface area and high porosity, the nanofiber PCMs demonstrated better thermal energy charging and discharging performance than the traditional bulky form-stable PCMs. – PCMs can be incorporated into nanofibers by electrospinning blend solutions containing polymers and PCMs . Our group encapsulated lauric acid (LA) into polystyrene (PS) nanofibers using the blend electrospinning method and achieved high PCM loadings of up to 80% .…”
