Complexing blends of polyacrylic acid-polyethylene glycol and poly(ethylene-co-acrylic acid)-polyethylene glycol as shape stabilized phase change materials

Self-crosslinkable complexes based on poly(ethylene glycol) (PEG), poly(itaconic acid) (PIA) and N-methylol acrylamide (NMA) as pharmaceutical hydrophilic matrices

“…1a), the intensity of CH 2 vibration band at 2883 cm -1 is higher as compared to the absorption band of OH groups around 3425 cm -1 (not clear in the spectrum). This observation is in agreement with the literature [15].…”

Enhanced comprehensive performance of polyethylene glycol based phase change material with hybrid graphene nanomaterials for thermal energy storage

“…To solve these two problems, several reports have focused on preparing shapestabilized PCMs and improving the thermal conductivity. Polymers [14,16,17], expanded graphite [18], carbon nanospheres [19], silicon dioxide [20], activated carbon [21], diatomite [22,23] and graphene oxide [12] (GO) have been employed as supporting materials to prepare shape-stabilized PCM. Thermal conductive PCMs were obtained by the introduction of conductive fillers such as graphite foams [24], carbon nanotubes [25,26], graphene nanomaterials [25,[27][28][29][30][31], boron nitride [32] and metal materials [33][34][35].…”

“…Polyethylene glycol (PEG) is a promising solid-liquid organic PCM owing to its desirable characteristics including high phase change enthalpy, chemical and thermal stability, biodegradation, non-toxicity, non-corrosiveness, low vapor pressure and suitable melting temperature which can be easily tuned by its molecular weight [4,[12][13][14][15].…”

Synthesis and thermal properties of cross-linked poly(acrylonitrile-co-itaconate)/polyethylene glycol as novel form-stable change material

“…Among the PCMs investigated, PEG is taken as a promising PCM because of its nontoxicity, relatively large fusion heat, congruent melting behavior, resistance to corrosion and ease of chemical modification [9][10][11]. However, the melted PEG has to be kept in a closed tank or container to prevent leaching during the phase transition, which not only increases production costs, but also reduceses the heat transfer efficiency.…”
