Poly(ethylene glycol)/acrylic polymer blends for latent heat thermal energy storage

Abstract: In the present study, polyethylene glycol (PEG) were blended with acrylic polymers like polymethyl methacrylate (PMMA), Eudragit S (Eud S), and Eudragit E (Eud

“…enthalpies was mainly caused by a retardation of the crystallization process of PEG in the composite fibers, which not only hindered by the quench process of electrospinning 30,33,34 but also influenced by the hydrogen bonding interactions between the PEG and CA chains. 6,23,35 Since the solvent removed from the polymer in subsecond time scales during the electrospinning process, the molecular chains of PEG have no time to form a well-defined, microscale equilibrium structure in the composite fibers. Meanwhile, PEG was found to be both distributed on the surface and within the core of the composite fibers, 23 the crystalline areas of PEG were very tiny within ultrafine fiber with a few microns, and surrounded by hydrogen bonding between the OH group of PEG and the carbonyl group of CA.…”

“…3,7 Therefore, a novel class of polymer-matrix PCMs as LHTES materials has been developed in the last decade for their unique advantages such as direct use without additional encapsulation, cost-effective, shape-stable, and easily prepared with desirable dimensions. 6,[9][10][11][12][13][14][15][16][17] These superior properties over traditional PCMs have directed researchers to focus on the development of new type form-stable or shape-stabilized PCMs. With the development of nano science and technology, some of new techniques are exploited and involved in the research of form-stable PCMs.…”

“…The major problem is that PEG needs encapsulation in order to prevent leakage of melted PEG during the phase change process, which results in extra thermal resistance and cost. Now, the problem can be solved by using two methods: the one is shape-stabilized composites which can be prepared by encapsulation of the PCM in a polymeric structure, such as high-density polyethylene (HDPE) [9,10] and the styrene-utadiene-styrene (SBS) copolymer [11]; the other is the PCM wallboard and PCM concrete blocks which can be fabricated by impregnation of the PCM in gypsum wallboard [12][13][14] and concrete [15].…”

“…In this field, Alkan et al [80] studied PEG blends with acrylic polymers such as PMMA, Eudragit S (Eud S, copolymer of methacrylic acid and methyl methacrylate), and Eudragit E (Eud E, copolymer based on dimethylaminoethyl methacrylate, butyl methacrylate, and methyl methacrylate) as formstable PCMs. The PEG acted as a phase change LHTES material with the acrylic polymers as supporting materials.…”
