“…The infrared thermogram in Figure 9 shows similar surface temperature distribution on the all developed electrothermal CCGA with various concentrations during the electrification process. It can be found from Figure 9d that the electrothermal CCGA showed similar temperature rise law to the previously reported GP or CNTs-based electrothermal materials [42,43,64]. Under the applied power density of 2000 W m −2 , all the electrothermal CCGA had a rapid heating rate and reached the maximum steady-state temperature rise in about 500 s. Even the concentration was as low as 3 mg mL −1 , the CCGA had the similar temperature rise and heating rate, signifying that the density of CCGA can be reduced to elevate its porosity.…”

“…It can be also concluded from the resistance change rate that the real power at the running state was higher than the set power. As seen from Figure 9d, the temperature rise was about 40 °C at the 7 mg mL -1 , which was lower than the NFC-GP membrane under the same power density of 2000 W m -2 [43]. However, the resistance change rate of the electrothermal CCGA (nearly 15% at the 7 mg mL -1 ) was much less than that of the NFC-GP membrane (about 37% while the addition of GP was 50 wt.%) under the same power density of 2000 W m -2 [43].…”

Nanofibrillated cellulose (NFC) as an environmentally friendly substrate material has superiority for flexible electrothermal composite, while there is currently no research on porous NFC based electrothermal aerogel. Therefore, this work used NFC as a skeleton, combined with multi-walled carbon nanotubes (MWCNTs) and graphene (GP), to prepare NFC/MWCNTs/GP aerogel (CCGA) via a simple and economic freeze-drying method. The electrothermal CCGA was finally assembled after connecting CCGA with electrodes. The results show that when the concentration of the NFC/MWCNTs/GP suspension was 5 mg mL−1 and NFC amount was 80 wt.%, the maximum steady-state temperature rise of electrothermal CCGA at 3000 W m−2 and 2000 W m−2 was of about 62.0 °C and 40.4 °C, respectively. The resistance change rate of the CCGA was nearly 15% at the concentration of 7 mg mL−1 under the power density of 2000 W m−2. The formed three-dimensional porous structure is conducive to the heat exchange. Consequently, the electrothermal CCGA can be used as a potential lightweight substrate for efficient electrothermal devices.

“…Devices for these purposes include supercapacitors [64,80,130], hydrogen storage devices [131], electrodes for hydrogen evolution reaction [132], lithium ion batteries [133], actuators [81], solar steam generators [82] and electric heating membranes [83]. These devices can be based on pure nanocellulose/nanocarbon composites without additives [80][81][82][83]. However, they often contain additives such as manganese oxide (MnO), which contributes to faradaic pseudocapacitance in supercapacitors [130] or polypyrrole, which acts as an insulator, but its oxidized derivatives are good electrical conductors [134].…”

“…In addition to its advantageous combination with nanocarbon materials, nanocellulose is an appealing material for biomedical applications due to its tunable chemical fluorescence and luminescence [26,71,72] photothermal activity [56], hydrolytic stability [61], nanoporous character and high adsorption capacity [49,61]. Nanocellulose/nanocarbon composites can therefore be used in a wide range of industrial and technological applications, such as water purification [22,29,43,49,54,56,61,[73][74][75][76], the isolation and separation of various molecules [22,74,[77][78][79], energy generation, storage and conversion [21,23,44,47,64,[80][81][82][83][84][85], biocatalysis [86], food packaging [67][68][69]87], construction of fire retardants [48], heat spreaders [70] and shape memory devices [38,[88][89][90].

Nanocellulose/nanocarbon composites are newly emerging smart hybrid materials containing cellulose nanoparticles, such as nanofibrils and nanocrystals, and carbon nanoparticles, such as “classical” carbon allotropes (fullerenes, graphene, nanotubes and nanodiamonds), or other carbon nanostructures (carbon nanofibers, carbon quantum dots, activated carbon and carbon black). The nanocellulose component acts as a dispersing agent and homogeneously distributes the carbon nanoparticles in an aqueous environment. Nanocellulose/nanocarbon composites can be prepared with many advantageous properties, such as high mechanical strength, flexibility, stretchability, tunable thermal and electrical conductivity, tunable optical transparency, photodynamic and photothermal activity, nanoporous character and high adsorption capacity. They are therefore promising for a wide range of industrial applications, such as energy generation, storage and conversion, water purification, food packaging, construction of fire retardants and shape memory devices. They also hold great promise for biomedical applications, such as radical scavenging, photodynamic and photothermal therapy of tumors and microbial infections, drug delivery, biosensorics, isolation of various biomolecules, electrical stimulation of damaged tissues (e.g., cardiac, neural), neural and bone tissue engineering, engineering of blood vessels and advanced wound dressing, e.g., with antimicrobial and antitumor activity. However, the potential cytotoxicity and immunogenicity of the composites and their components must also be taken into account.

Halide perovskite solar cells (PSCs) have drawn worldwide attention due to their great potential to be promising candidates for highly efficient and cost-effective photovoltaic technologies. [1] Benefiting from the excellent optoelectronic properties of halide perovskites together with previous abundant experience in other solar cells, especially in dye-sensitized solar cells and organic solar cells, the power conversion efficiency (PCE) of conventional PSCs has been boosted to 25.5%, [2] making PSCs one of the most efficient solar cell type. Conventional efficient PSCs in lab usually rely on costly materials such as gold or silver electrode and organic hole transport materials (HTM). [3] To further reduce the material and fabrication cost of PSCs toward commercialization, carbon electrode-based HTM-free perovskite solar cells (C-PSCs) are developed. [4] In C-PSCs, carbon electrodes (CEs) are chosen to replace metal electrodes due to their excellent adjustable electronic properties, chemical stability and low cost. [5] However, the efficiency of C-PSCs has not exceeded 20%. [6] Therefore, developing carbon materials for C-PSCs to promote their efficiency toward the comparable level as conventional PSCs is in great demand. [4] Since no additional HTM is applied in C-PSCs, adjusting the work function (WF) of CEs to realize more efficient hole extraction and more suitable energy level alignment is an effective strategy to enhance the efficiency of C-PSCs. [7,8] To realize this, Jiang et al. introduced p-type metal oxides into the CE to improve its WF for extracting holes. [9] However, the introduction of those metal oxides led to the sheet resistance increase of CEs, which resulted in series resistance increase of the C-PSCs and restricted the efficiency improvement. Doping graphite has been demonstrated as another effective method to adjust the CEs WF for improving C-PSCs performance. Duan et al. improved the efficiency of C-PSCs from 12.4% to 13.6% by applying boron-doped carbon as the electrode. [5] Yang's group improved the WF of CE and the efficiency of C-PSCs by doping graphite with boron. [10] In addition, it is found that introducing oxygen-containing functional groups into the CE can also increase the WF. Tian et al. synthesized a carbon black with much higher oxygen content and a much higher WF than common carbon black. [11] When applying it in the CE for C-PSCs, the device efficiency was enhanced from 13.6% to 15.7%. This work demonstrated that introducing oxygen into CEs is of great potential to improve C-PSCs efficiency. However, the restriction is that the related process for introducing oxygen is carried out at high temperature of about 1600 K. Therefore, developing facile methods to synthesize oxygen-rich carbon materials sustainably for CEs is worth exploring.Biomass materials, which hold the "Sustainable and green" characteristics, have been applied for different energy conversion devices.
