“…An understanding of the thermal properties is required to design polymer structures with temperature‐dependent oxygen and water vapor permeabilities . On the basis of Figure and Table , we surmised how the OD content affected the morphological structure, such as the amorphous and crystalline structure, in the pure PP matrix.…”

Polypropylene (PP)/octadecane (OD) composite films were prepared via twin-screw extrusion, and their chemical, morphological, thermal, and surface properties and oxygen and water vapor permeabilities were analyzed as functions of the OD content and temperature. OD was dispersed well in the PP matrix, and two phases (i.e., the PP and OD portions) were present in the PP/OD composite films. When the temperature was increased from 10 to 30 8C, both the oxygen transmittance rate and the water vapor transmittance rate of the PP/OD composite films increased sharply because of the influence of the OD content. These results were related to the temperature-dependent changes in the morphological structure, such as changes in the the tortuous paths and crystallinity in the composite films because of the addition of OD. In the storage test, the PP/OD (83:17) composite films continuously controlled the gas concentration of the headspace and protected against environmental factors; this reduced the enzymatic activity and led to higher quality cherry tomatoes compared to the case when the pure PP and MP33000 films were used.

“…Otherwise, when the ambient temperature exceeds the melting temperature of the PCMs, the PCM can leak from the porous material and consequently jeopardize the performance of the system. Previous research has primarily focused on the preparation of shape stable encased/encapsulated PCMs [19] and/or on characterization of the thermal and mechanical properties of the composites [20,21], whilst the issue concerning PCMs leakage from porous material has not been adequately addressed. It must be stressed at this point that, possible leakage of PCMs will reduce the heat storage capacity of the composite and consequently will decrease the functionality and effectiveness of the PCMs composites [22].…”

“…Among many synthesizing methods regarding form‐stable PCMs, such as the microencapsulation of PCM or the impregnation of PCM into porous matrix. The shell materials used to fabricate form‐stable PCMs include expanded graphite, low density polyethylene (LDPE), metal foam, silica, graphitic carbon nitride and montmorillonite nanosheets, etc. However, the form‐stable phase change materials still face some challenges concerning encapsulation: the fracture of the support shell caused by the volume stress generated by PCM during the phase transition and requirement of mechanical properties in some practical application, particularly in building structural materials .…”

This work presents a novel eutectic hydrate salt/self-curing acrylic resin formstable phase change materials (PCMs) composite (EHS/SCR) with favorable form-stable performances for heat energy storage. Further, to improve the surface stability, latent heat and thermal conductivity of the EHS/SCR particles, graphene oxide (GO) used as cladding materials is incorporated onto the surface of the EHS/SCR particles to prepare the GO modified EHS/SCR phase change composite (EGO). The obtained results indicate that the GO-targeted absorption model has achieved the enhancements in stability and thermal properties of EHS/SCR while making use of GO in an efficient and economical way. To be specific, with the introduction of GO of only 1.07 wt%, the thermal conductivity of 0.508 W/mÁK is achieved, the value shows a significant rise of 128.6% compared with the EHS/SCR of 0.222 W/mÁK. Additionally, the maximum latent heat of EGO-6 is up to 90.4 J/g, which exhibits a 3.19-fold increase compared against that of the uncoated EHS/SCR. Moreover, the prepared EGO composite PCM remain a good thermal cycling reliability after 300 thermal cycles. This work provides a novel opportunity to improve the performance of form-stable PCM composites with an intelligent manufactureoriented pattern.
