“…The phase change behavior of the PEG-MgO ss-PCMs is similar to that of the pure PEG. The T m,o of PEG-MgO ss-PCMs are depressed compared to that of pure PEG as reported owing to an increase in the surface energy under nanoconfinement [47]. The depressed melting point (T m ) can be estimated from the Gibbs-Thomson equation by Eq.…”

“…The traditional heat storage methods are divided into three types: chemical reaction heat, latent heat, and sensible heat storage. Among them, latent heat storage has higher energy storage capacity and can maintain an almost constant temperature in the process of heat storage and heat rejection, which is widely used in building energy conservation, − solar-thermal energy utilization, − industrial waste heat utilization and waste heat recovery, − and textile clothing. , …”

A new form-stable composite phase change material (CPCM) of capric acid-stearic acid-paraffin wax/expanded graphite (CSPW/EG) was prepared by vacuum adsorption. CSPW has a minimum crystallization temperature of 21.9 °C at the eutectic mass proportion of 74.7:8.3:17 by the step cooling curve method and has a phase change temperature of 25.27 °C and an enthalpy of 126.82 J/g by differential scanning calorimetry (DSC). The mixing proportion of CSPW to EG was determined to be 10:1 based on the enthalpy change and leakage of CPCMs; the enthalpy and phase transition temperature of CSPW/EG were 119.26 J/g and 27.14 °C, respectively. The microstructure, crystal structure, and chemical structure of CSPW/EG were characterized by using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD). The initial weight loss temperature of CSPW/EG was 159.8 °C, which is far beyond the working temperature. The heat storage-release experiments and 1000 melting−solidification cycles also confirmed that CSPW/EG has excellent heat energy storage and temperature control ability, thermal reliability, and great potential in practical engineering heat storage applications.

“…Mesoporous silica (MS) materials are attracting great interest in the eld of microreactor [1,2]. Thanks to their excellent porous structure and characteristics (such as, tractable surface morphology [3], consistent and exible pore size [4], spacious interior space that can protect interaction independence from external environment and their compatibility [5,6]), MS features prominently in nanodevices [7], drug delivery [8,9], adsorption [10,11], separation [12], photonic waveguides [13], and biometrics [14].…”

Reversible addition fragmentation transfer (RAFT) polymerization is of key signi cance for its suitability for most monomer and well-studied reaction mechanism. Herein, a serial of mesoporous silica (MS) materials, including rod-liked and spherical SBA-15, spherical MCM-41, and MCM-48, were successfully synthesized and modi ed by silane coupling agent γ-aminopropyltriethoxysilane (KH550). The modi ed MS was utilized as a microreactor for reversible addition-fragmentation chain transfer (RAFT) polymerization of methyl methacrylate (MMA) using a xanthate as a chain transfer agent and AIBN as an initiator. Note that modi ed MS had lower speci c surface area and pore volume while maintained the original morphological structure. Owing to the con nement effects, poly(methyl methacrylate) (PMMA) prepared from internal mesoporous channels featured with higher molecule weight and initial thermal decomposition temperature than these from conventional RAFT polymerization. More importantly, the PMMA obtained from the spherical SBA-15 and modi ed MCM-48 exhibited the highest molecule weight.This work provided a novel approach to design of polymer microstructure for a wider application, such as in drug release. AR), ammonia water (NH 3 •H 2 O, 25-28%), tetraethyl orthosilicate (TEOS, AR), hydro uoric acid (HF, ≥ 40%) hydrochloric acid (HCl,(36)(37)(38), and tetrahydrofuran (THF, AR) were all purchased from Xilong Science and Technology Co., Ltd. MMA was treated with 10% aqueous NaOH solution for three times to remove the inhibitor, then washed with distilled water to be neutral, dried with anhydrous CaCl 2 , and distilled under reduced pressure. Anhydrous ethanol (AR) was purchased from Guangdong Guanghua Technology Co., Ltd. Azodiisobutyronitrile (AIBN, AR), purchased from Tianjin Guangfu Fine Chemical Research Institute, was used after recrystallization from absolute ethanol. Potassium ethyl xanthate (AR) and ethyl 2-bromopropionate (AR) were purchased from Aladdin Industrial Corporation (Shanghai, China) and used directly. γ-aminopropyltriethoxysilane (KH550, CP) was purchased from Nanjing Xiangfei Chemical Research Institute. Ethyl xanthate ethyl propionate was synthesized according to the reported work [24]. All other chemicals were used as received without further puri cation.
