“…A survey of literature shows that a number of studies have been carried out on microPCMs using different inorganics, natural or synthetic polymers as microcapsule shell materials. MicroPCMs have been widely applied in solid matrix as smart temperatureregulation composites, such as fibers, construction materials, and functional packaging materials [11][12][13]. The core materials in microPCMs are usually organic solid-liquid materials such as paraffin (C n H 2n+2 ) and fatty acids (CH 3 (CH 2 ) 2n COOH) [14][15][16].…”

Microencapsulated phase change materials (microPCMs) have been widely applied in solid matrix as thermal-storage or temperature-controlling functional composites. The thermal conductivity of these microPCMs/ matrix composites is an important property need to be considered. In this study, a series of microPCMs have been fabricated using the in situ polymerization with various core/shell ratio and average diameter; the thermal conductivity of microPCMs/epoxy composites were investigated in details. The results show that the microPCMs have smooth surface and regular global shape with compact methanolmelamine-formaldehyde shell. The shell thickness does not greatly influence the phase change behaviors of PCM. Moreover, smaller microPCMs embedded in epoxy can improve the thermal transmission ability of composites. The effect of thermal conductivity of composites can be improved with higher volume fraction (10-30%) of microPCMs; and smaller size microPCMs with the same content of PCM may also enhance the thermal transmission area in matrix. Modeling analysis of relative thermal conductivity indicates that mixing higher thermal conductivity additive in PCM or matrix is an appropriate method to improve the thermal conductivity of microPCMs/matrix composites.

“…Thermo-regulated shell/core composite fibres containing 4-24 % of microencapsulated n-octadecane were investigated [91]. The results indicated that the enthalpy of the fibres was approximately 11 kJ/kg and the fibres also presented acceptable mechanical strength; as the content of MEPCM was not exceed 20 wt %, which could be used for fabric materials production.…”

The use of latent heat storage, microencapsulated phase change materials (MEPCMs), is one of the most efficient ways of storing thermal energy and it has received a growing attention in the past decade. However, there is no complete overview of its utilisation in thermal energy storage systems, and the information is widely spread in the literature. In this paper, a comprehensive review has been carried out for MEPCMs. Four aspects have been the focus of this review: fabrication and characterization of MEPCMs, applications of MEPCMs to the textile and building, fundamental properties of microencapsulated phase change material slurry (MPCS) and application of MPCS to the thermal energy storage system. Over 140 recent publications are referenced in this paper.

“…Fundamentally, by comparing the permeability coefficient of the shells (k), the minimum can be chosen fabricated by different preparation processes. Most of release properties observed in experiments have been analyzed by kinetic theories based on Fick's Law with an assumption that the release rate is proportional to the concentration gradient of solutes [13,14]. As each microcapsules system has different structure shell and core material, it is considered to be complex system [15] and required to employ different strict treatment to understand the release mechanism and to characterize such complex system clearly.…”
