A novel UV‐cured interpenetrating organic–inorganic hybrid polymer network based phase change materials (IPN‐PCM)

Abstract

The purpose of this paper is to introduce a novel UV‐cured interpenetrating polymer networked phase change materials (IPN‐PCMs), on which no article has been found in the so far published research. Maleated castor oil (MCO) was synthesized via maleinization reaction of castor oil with maleic anhydride. Organic–inorganic hybrid interpenetrating polymer networked (IPN) materials containing both cationic and radical sections and IPN‐PCMs containing tetradecanol, hexadecanol, and octadecanol were prepared. The chemical structure of MCO and organic–inorganic hybrid IPN‐PCMs were determined by using Fourier Transform Infrared Spectroscopy (FT‐IR). Differential scanning calorimetry (DSC) was used for examining the phase‐change behaviors of the materials. Thermal stability was investigated by thermogravimetric analysis (TGA). Moreover, the surface formation of the specimen was investigated by scanning electron microscopy (SEM). In conclusion, our study proved that because of their high latent heat storage scope and high thermal stability, the obtained organic–inorganic hybrid IPN‐PCMs could be used as thermal energy storage materials.

Recent Advances in Polymer‐Containing Multifunctional Phase‐Change Materials

“…However, the formidable challenges still exist in the performance of solid‐liquid PCMs, such as liquid leakage during the phase change process and poor thermal conductivity. Therefore, a shape‐stabilized PCMs (SSPCMs) which generally constituted by a working material and a supporting material has emerged as an important protocol for the use of solid‐liquid PCMs [27–30] . There are many types of supporting materials, such as inorganic porous materials, polymer materials, carbon‐based materials and so on [31,32] .…”

Synthesis of a novel Zn‐MOF/PVA nanofibrous composite as bioorganic material: Design, systematic study and an efficient arsenic removal

“…Inorganic materials with combination of functionalized polymers are very interesting way to achieve advanced properties in field of chemistry and material science. [1][2][3][4][5][6][7] Metal organic frameworks (MOFs) along with polymerization have shown a large extent of porosity and a high surface area in for catalysis, energy storage devices and membrane for gas separation, ion exchange, and biomedical applications. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] In recent years, heavy metal pollution has increased as a result of the evolution of the chemical industry and the introduction of toxic compounds into water.…”
