“…8 Furthermore, because of their biodegradable and recyclable nature, paper devices meet the trends of next-generation green technology, resulting in rapid market-size growth. 9 Benefiting from printing technology, various electronic components on paper substrates have been developed, such as transistors, 10 memory, 11 detectors, 12 capacitors, 13 resistors, 14 diodes, 15 and power generators, 16 which by integrating these elements into functional circuits enable advanced applications, including nanopaper antennas, 17 paper-based lithium-ion batteries, 18 and radio frequency identification tags. 19 However, due to the extremely low thermal conductivity of plastic and paper substrates, 20,21 heat dissipation problems exist in both device types, making it difficult for them to function at high temperatures.…”

Flexible electronics are expected to play a key role in connecting human lives with versatile smart electronic devices due to their adaptability to different shapes, surfaces, and even the human body. However, heat management issues found in most flexible devices due to the low thermal conductivity of conventional plastic or paper substrates become significant for large-scale integration or high-temperature applications. In this study, we employed high thermal conductivity nanopaper composed of twodimensional (2D) hexagonal boron nitride nanosheets and one-dimensional nanofibrillated cellulose to form a flexible deepultraviolet photodetector demonstrating superior photodetectivity of up to 8.05 × 10 10 cm Hz 1/2 /W, a short response time of 0.267 s, and excellent flexible durability featuring repeatable ON/OFF photoswitching over 200 bending cycles. Because the boron nitride paper has a high thermal conductivity of 146 W/mK, which is three orders of magnitude larger than plastic or paper substrates, the photodetectors can work at high temperatures of up to 200°C. The boron nitride paper-based strategy described herein suggests a path for improving heat dissipation in flexible electronics and achieving high-performance deep-ultraviolet photodetectors, which can be applied in wearable applications.

“…Recent studies have demonstrated that CNF substrates derived from wood 2,3 have good mechanical properties, low thermal expansion, good flexibility, and good biodegradability [4][5][6][7] and thus have the potential to serve as substrates for portable green electronics. Researchers have previously demonstrated the use of cellulose nanofibril composites as substrates for a variety of energy and electronic devices such as solar cells, [8][9][10] energy storage devices, 11 sensors, 12 organic TFTs, 13 lighting devices, 14 and displays. 15 These demonstrations have mainly taken the advantages of transparency and decomposition/dissolution properties of CNF.…”

In this paper, we demonstrate microwave flexible thin-film transistors (TFTs) on biodegradable substrates towards potential green portable devices. The combination of cellulose nanofibrillated fiber (CNF) substrate, which is a biobased and biodegradable platform, with transferrable single crystalline Si nanomembrane (Si NM), enables the realization of truly biodegradable, flexible, and high performance devices. Double-gate flexible Si NM TFTs built on a CNF substrate have shown an electron mobility of 160 cm2/V·s and fT and fmax of 4.9 GHz and 10.6 GHz, respectively. This demonstration proves the microwave frequency capability and, considering today's wide spread use of wireless devices, thus indicates the much wider utility of CNF substrates than that has been demonstrated before. The demonstration may also pave the way toward portable green devices that would generate less persistent waste and save more valuable resources.
