“… 178 In the case of solar harvesting, Huang et al combined TA with liquid metals to realize photothermal materials with high efficiency, which manifested strong broad-band light absorption (96.9–99.3%) and excellent photothermal conversion ability ( η PT = 77.3%). 179 In particular, TA-based MPN networks could also be utilized in (NIR) light-triggered actuation. As proposed by Wang et al , 180 a TA/WS 2 /polyurethane latex was coated onto a cellulose nanofiber film to form a bi-layer flexible device.…”

“…Generally speaking, hybrid mechanisms consist of two or two more fundamental mechanisms are mentioned above. For example, Huang et al, [ 90 ] developed one super‐robust photothermal liquid metals@polymer core‐shell material, which consists of plasmonic heating and thermal vibration of organic polymer mechanism during the heat production process. Zhang et al, [ 51 ] presented that the nanostructured silicon with gold nanoparticle deposition for photothermal conversion includes three fundamental mechanisms of non‐radiative relaxation below the cutoff wavelength, plasmonic heating, and multiple interactions within the nanostructures in the wavelength range from 200 to 1700 nm.…”

of monolithic silicon/perovskite solar cell has achieved over 29%. [13,14] Alternatively, photothermal conversion is another way to utilize solar energy and has drawn dramatically increasing attention due to the easily achievable large conversion efficiency (usually larger than 50%) for the applications in thermal catalysis, [15][16][17][18] water evaporation and desalination, [19][20][21][22][23][24][25][26][27] bacterial killing, [28] as well as thermal-responsive sensors. [29][30][31] Photothermal conversion of solar energy refer that solar energy is first converted into heat and then heat energy is utilized to achieve the desired destinations, [15,16,28,[31][32][33][34] such as water purification, desalination, electric power generation, catalysis conversion, bacterial killing, and actuators. Thus, photothermal conversions of solar energy can be supplementary to PV-based technology in solar energy conversion and are deemed to be extremely important to clean energy production. [19,35,36] Very recently, photothermal-derived applications have attracted many researchers' interests and great efforts have been taken to expand the application fields and increase the conversion efficiency based on solar energy conversion. [29,[37][38][39][40][41][42][43][44] Among all the applications, photothermal water evaporation for desalination and water purification has attracted the most attention, owning that freshwater can be directly produced by only using solar energy and it can address the freshwater shortage challenge for many countries. [27,32,33,[45][46][47][48][49][50][51][52][53] However, the research focusing on other applications has attracted less attention than photothermal water evaporation, which should also be taken equally important attention for making the most of solar energy. For example, photothermal catalysis for H 2 generation and CO 2 reduction can be applied to convert solar energy into chemical energy under high concentrated solar intensity, but the efforts are still far from enough. Although photothermal electric power generation can show a solar-to-electricity conversion efficiency exceeding 7% under 38 Sun, [54] its conversion efficiency remains very low under low concentration solar intensity, such as 1 Sun or ambient conditions. Thus, the tradeoff between efficiency, costs, and practicality should be considered in future works. In addition, photothermal bacterial killing technology has proved that it can be efficiently used for killing bacteria under solar light illumination, [28] but whether it can be applied for human or animal wound treatment still needs to be discussed. Furthermore, solar energy can also cause thermally sensitive objects to reversibly change the physical properties for Solar energy is a green, sustainable, and de facto inexhaustible energy source for mankind. The conversion of solar energy into other forms of energy has attracted extensive research interest due to climate change and the energy crisis. Among all the solar energy conversion technologies, photothermal conversio...

The high-density hydrogen bonds in the system endow the materials with efficient self-healing ability at room temperature . In addition, the chain rigidity of CT and the low content of covalent cross-linking introduced by it cause the resin to maintain a balance between mechanical properties and repair ability .…”

The rapid development of thermosetting polymers contributes strongly to environmental pollution, petrochemical resource consumption, and increasing carbon dioxide emission. Introducing a reversible supramolecular cross-linking network into the thermosetting polymer to endow it with reprocessability and self-healing ability is highly attractive for the reduction of fossil fuel consumption. Despite the tremendous advancement in recyclable thermosetting polymers, using biobased materials to construct reversible cross-links, which can realize the high biomass carbon content of materials, remains challenging. Here, we present a selfhealing and reprocessable epoxy resin enabled by biobased multiple hydrogen bonds between biological tannic acid and chitosan. The binding energy simulation demonstrates that effective hydrogen bonds are constructed in the epoxy resin. The resultant supramolecular cross-linked epoxy resin shows improved mechanical properties (tensile strength increased by two times, toughness increased by 2.7 times), high self-healing efficiency (104% toughness recovery) at room temperature, and excellent reprocessability (109% toughness recovery). We envision that the proposed biobased reversible cross-linking strategy will be useful in the greening and recycling of various thermosetting polymers, such as rubbers, crosslinked plastics, etc.
