Thermal Stability Of

The expanded graphite/stearic acid composite phase change materials were prepared with stearic acid as phase change materials and expanded graphite as the carrier by the adsorption and encapsulation of expanded graphite. The thermal stability of composite phase change materials were analyzed by TG, XRD and SEM. Results showed that expanded graphite has reticular structure to encapsulate the stearic acid, improving its stability of thermal decomposition, thermal cycle and thermal chemical. When the content of expanded graphite is 10wt. %, the composite phase change materials exhibit good thermal stability, and can meet the requirements of temperature control under different conditions.

This paper investigated the thermal performance of shape stabilized phase change paraffin and shape-stabilized phase change fatty acid. And the PCMs are mixtures of 60% 46# paraffin and 40% liquid paraffin, 65 % 48# paraffin and 35% liquid paraffin,30%capric acid and 70% lauric acid, 30%capric acid and 70% myristic acid. Support material is high-density polyethylene. The results in this paper show that: Thermal stability of both of the two types of phase change materials are good, thermal stability of shape stabilized phase change fatty acid is better than that of paraffin. Results in this paper can provide references and basis for the application of phase change material walls in the practice building.

Crosslinked Networks

The novel form-stable composite phase change materials (PCMs) of crosslinked PEGA and P(PEGA-HAM)/PEG gels were synthesized, which based on PEGA . Using crosslinked PEGA and P(PEGA-HAM)/PEG gels as the working substance , PP/PCM thermo-regulating fibers were prepared by blends via melt spinning respectively. TGA results indicate that the crosslinked form-stable PCMs have good thermal stability. The morphology of the surface of PP/PCM thermo-regulating fibers smooth mainly by SEM. The breaking strength of thermo-regulating fibers first increases and then decreases when increased some content of PCM. DSC results indicate the phase enthalpy of PEGA crosslinked gel and its the blend fibers with PP are 122.97J/g and 13.83J/g, while that of P(PEGA-HAM)/PEG crosslinked networks gel and its the blend fibers with PP are 107.48J/g and 4.62J/g respectively.

Thermal Stability Of

The aim of this study is to investigate passive control strategies using Phase Change Materials in Machine Tools (MTs) thermostabilization. By considering the main issues related to the thermal stability, authors presented the application of novel multifunctional materials to Machine Tools structures. A set of advanced materials are considered: aluminium foams, corrugate-core sandwich panels and polymeric concrete beds. The adopted solutions have been infiltrated by phase change materials (PCMs) in order to maintain the thermal stability of MTs when the environmental temperature is perturbed. The paper shows the results of simulative and experimental tests.
