Super-flexible phase change materials with a dual-supporting effect for solar thermoelectric conversion in the ocean environment

“…[13][14][15][16] At present, the construction of solar thermoelectric systems with regard to energy conversion on land has been widely studied. [17][18][19] As is known, 71% of the Earth's surface is covered by oceans, on which the solar energy density is close to 1367 W m −2 . 20,21 However, most of the solar energy radiated on the ocean surface is directly dissipated to change the ocean temperature and salinity.…”

Highly Stretchable Ti3C2Tx MXene-Integrated Phase Change Films for Solar-Thermal Harvesting and Infrared Stealth

“…In the thermoelectric plate, the electron/hole pairs recombine at the heat sink end to release heat as they are excited by the absorption of heat at the MPSPCF-5 sample end. The voltage differential between the two ends generates the current flow as a result of such migration of the activated electron/hole pairs, which is known as the Seebeck effect . Herein, a photothermal-electric experiment was carried out under a solar-simulated light source with an intensity of 200 mW/cm 2 .…”

“…The voltage differential between the two ends generates the current flow as a result of such migration of the activated electron/hole pairs, which is known as the Seebeck effect. 63 Herein, a photothermal-electric experiment was carried out under a solar-simulated light source with an intensity of 200 mW/cm 2 . The output voltage/current curve of the MPSPCF-5 sample in the test is shown in Figure 6e, which is very similar to the temperature curve under light conditions.…”

Ultra-strong, nonfreezing, and flexible strain sensors enabled by biomass-based hydrogels through triple dynamic bond design

“…Recently, biomasses such as cellulose, hyaluronan (HA), lipoic acid (LA) and gelatin are utilized to fabricate hydrogels owing to their abundance, degradability, and biocompatibility. 3,14–19 Most synthetic hydrogels showed poor mechanical and nonfreezing properties during the deformation and freezing processes compared with petroleum polymer-based hydrogels. The reason is that the hydrogel structure with a high moisture content is loose by insufficient crosslinking of polymer chains, and the high moisture content induced the formation of ice crystals.…”
