“…Solar energy is a promising renewable energy for human beings and the earth's surface receives a large quantity of solar irradiation every day. The conversion of solar energy into heat is an appealing way to alleviate the energy crisis and environmental concerns and improve solar energy utilization efficiency [4][5][6][7]. However, solar energy is a representative time-dependent energy resource with an intermittent and discontinuous attribute, which has undermined its widespread exploitation and commercial applications.…”

Conversion of solar energy into thermal energy stored in phase change materials (PCMs) can effectively relieve the energy dilemma and improve energy utilization efficiency. However, facile fabrication of form-stable PCMs (FSPCMs) to achieve simultaneously energetic solar–thermal, conversion and storage remains a formidable challenge. Herein, we report a desirable solar–thermal energy conversion and storage system that utilizes paraffin (PW) as energy-storage units, the silver/polypyrrole-functionalized polyurethane (PU) foam as the cage and energy conversion platform to restrain the fluidity of the melting paraffin and achieve high solar–thermal energy conversion efficiency (93.7%) simultaneously. The obtained FSPCMs possess high thermal energy storage density (187.4 J/g) and an excellent leak-proof property. In addition, 200 accelerated solar–thermal energy conversion-cycling tests demonstrated that the resultant FSPCMs had excellent cycling durability and reversible solar–thermal energy conversion ability, which offered a potential possibility in the field of solar energy utilization technology.

“…Different from 1D cellulose polymer, carbon nanotubes (CNTs) not only possess remarkable mechanical properties, but also inherently possess strong photoabsorption and electrical conduction capacities ( Chen et al., 2020d , 2020g ; Tang et al., 2021 ). CNTs have been widely used for flexible wearable composite PCMs owing to their unique properties such as high thermal conductivities (2000–6000 W/m·K), high flexibility and superior mechanical properties ( Hirsch, 2010 ).…”

“…Thermal storage materials that use latent heat to store energy have received unprecedented attention [14][15][16]. Phase change materials (PCMs) with high energy storage density and near-isothermal process are widely used in applications with diverse energy utilization, including photovoltaic thermal management [17], solar water heater systems [18], building energy efficiency [19], lithium-ion battery thermal management [20][21], wearable fabric [22][23], photon ap-plication field [24][25], high-temperature energy storage [26], and smart windows [27][28]. By adding PCMs to ordinary building materials to prepare phase change energy storage building materials with large heat storage capacity, indoor temperature fluctuations are reduced, and the thermal storage capacity of envelope structures is improved, thereby effectively reducing building energy consumption and achieving energy saving and emission reduction [29].…”

Mica was used as a supporting matrix for composite phase change materials (PCMs) in this work because of its distinctive morphology and structure. Composite PCMs were prepared using the vacuum impregnation method, in which mica served as the supporting material and polyethylene glycol (PEG) served as the PCM. Fourier transform infrared and X-ray diffraction analysis confirmed that the addition of PEG had no effect on the crystal structure of mica. Moreover, no chemical reaction occurred between PEG and mica during the vacuum impregnation process, and no new substance was formed. The maximum load of mica-stabilized PEG was 46.24%, the phase change temperature of M 400 /PEG was 46.03°C, and the latent heat values of melting and cooling were 77.75 and 77.73 J•g −1 , respectively. The thermal conductivity of M 400 /PEG was 2.4 times that of pure PEG. The thermal infrared images indicated that the thermal response of M 400 /PEG improved relative to that of pure PEG. The leakage test confirmed that mica could stabilize PEG and that M 400 /PEG had great form-stabilized property. These results demonstrate that M 400 /PEG has potential in the field of building energy conservation.
