Zeolitic imidazolate framework-67 for shape stabilization and enhanced thermal stability of paraffin-based phase change materials

Abstract

Micro-sized ZIF-67 crystals were prepared and used as the reinforcing material to design novel paraffin-based composite phase change materials with a polymethyl methacrylate shell.

“…The peaks from 1340 to 880 cm À1 and below 800 cm À1 can be assigned to the in-plane and out of plane vibrations of the imidazole ring. 52 The FTIR spectrum of Co 3 O 4 exhibits peaks at 561 and 660 cm À1 corresponding to the Co-O stretching vibration and bridging vibration of the O-Co-O bond, respectively. 53 Fig.…”

Fabrication of Organic Shape-stabilized Phase Change Material and Its Energy Storage Applications

“…Polymethyl methacrylate (PMMA) is a light weight polymer with high mechanical strength which was also used in SSPCM fabrication. [146] Chen [34] uses PDVB-SO3H and PDVB-SO3Na as supporting materials to encapsulate ODA, showing extraordinarily high phase change entropy which reaches 437 J/g which has never been reported before in organic PCMs.…”

Voltammetric Determination of Rhodamine B Using a ZIF-67/Reduced Graphene Oxide Modified Electrode

“…The absorption band centered at 3441 cm -1 is assigned to the stretching of OH in water adsorbed in material. The main absorption peaks from 600-1500 cm -1 are assigned to the vibrations of functional groups in 2-methylimidazole, in which the peak at 1578 cm -1 can be attributed to the stretching vibration of C=N bond and the peak at 2924 cm -1 belongs to the symmetric stretching vibration of CH 3 [17]. The absorption band at 1573 cm -1 in the FT-IR spectrum of rGO can be attributed to the skeletal vibration of graphene sheets.…”
