“…At ΔT = 50 °C, a V AC of 22 mV was measured, much higher than those reported previously. 32,35 Given the Seebeck coefficients, the actual TE output powers (P AC ) can be obtained and compared with the theoretically expected values (P TH ). In particular, when the internal resistance (R r ) equals the load resistance (R L ), the output power versus R L reaches its maximum for a given number of p− n junctions, as shown by the peaks in Figure 4d.…”

Taking advantage of the high electrical conductivity of a single-walled carbon nanotube (SWCNT) and the large Seebeck coefficient of rylene diimide, a convenient strategy is proposed to achieve high-performance n-type thermoelectric (TE) composites containing a SWCNT and amino-substituted perylene diimide (PDINE) or naphthalene diimide (NDINE). The obtained n-type composites display greatly enhanced TE performance with maximum power factors of 112 ± 8 (PDINE/SWCNT) and 135 ± 14 (NDINE/SWCNT) μW m K. A short doping time of 0.5 h can ensure high TE performance. The corresponding TE module consisting of five p-n junctions reaches a large output power of 3.3 μW under a 50 °C temperature gradient. In addition, the n-type composites exhibit high air stability and excellent thermal stability. This design strategy benefits the future fabricating of high-performance n-type TE materials and devices.

“…Very recently, BC composited with PEDOT and PANI showed electrical conductivities in the range of 10 S cm –1 for the in situ generation of composites,33 while 1 × 10 –2 S cm –1 has been reported for composites prepared by filtration of CNTs through an already grown BC membrane 34. Given these promising results for the electrical conductivity, as well as other attractive properties of BC composite films, such as the BC low thermal conductivity k of around 0.5 W m –1 K –1 ,35,36 there has been surprisingly little research effort to explore the use of these materials in thermoelectric devices, besides the use of paper filters as cheap substrates 37…”

“…efforts have focused on improving performance through the enhancement of thermal energy transfer, internal polarization, pyroelectric coefficient, and structural design of NGs. [11] The use of cellulose to prepare products with thermoelectricity or pyroelectricity has been explored by i) incorporating thermoelectric material in cellulose paper, films, membranes, coatings, and aerogels; [130][131][132][133][134][135] ii) incorporation/blending cellulose and its derivatives with polymers that exhibit electrochemical response upon temperature change; [136][137][138] and iii) using cellulose and its derivatives as fillers and binders. [139] To date, only a couple of studies (Table 3) have reported the use of cellulose in pyroelectricity generation, probably due to lack of its inherent pyroelectricity, thermal insulation and sensitivity to moisture and other variabilities.…”

Developing nanogenerators (NGs) is achieved by exploiting the piezoelectric, triboelectric, and pyroelectric effects of both organic and inorganic materials. Many exhibit beneficial electrical properties (dielectric, conductive, or insulating) or have surfaces that are polarizable upon friction or physical contact. Recently, biomass‐derived materials and recycled materials, whose electrical activity can be induced, are explored for application in the design of more sustainable, cost‐effective, biodegradable, disposable NGs, and have demonstrated a wide range of output (microenergy) power densities. Among them, cellulose, the most abundant biopolymer, is found to offer excellent opportunities for designing and manufacturing NGs with multifunctional capacities. Cellulose can be derived into varied forms with multifunctionalities and physical morphologies. This account provides an overview of how cellulose is utilized in creating NGs based on piezoelectric, triboelectric, and pyroelectric effects. Because the mechanical properties of cellulose are tunable, current research trends on NGs originate with the triboelectric effect. The discussion here focuses on design, fabrication methods, achievable electrical power output, and combinations with other materials and devices. Challenges in efficient fabrication and consistent power densities, and opportunities for integrating different technologies and developing more sustainable (in terms of economic, environmental, and ecological) nature–human–machine interfacial devices are also discussed.
