“…Increasing the number of twist-untwist cycles beyond 100 did not induce any further increase in the maximum oscillation range of 4%. Although a five-fold increase is evident, the final sheet resistance is comparable or better than other reported carbon-based flexible conductors [45][46][47] or non-carbon-based conductors undergoing similar fatigue tests, [48,49] which are not based on "bioadvantaged" plant-based resources (see Table S1, Supporting Information, for more details). Indeed, three light-emitting diodes (LEDs) were uninterruptedly powered at a voltage of 12 V with the biocomposite undergoing several twist-untwist events without any loss in brightness.…”

In today's fast‐paced and well‐connected world, consumer electronics are evolving rapidly. As a result, the amount of discarded electronic devices is becoming a major health and environmental concern. The rapid expansion of flexible electronics has the potential to transform consumer electronic devices from rigid phones and tablets to robust wearable devices. This means increased use of plastics in consumer electronics and the potential to generate more persistent plastic waste for the environment. Hence, today, the need for flexible biodegradable electronics is at the forefront of minimizing the mounting pile of global electronic waste. A “bioadvantaged” approach to develop a biodegradable, flexible, and application‐adaptable electronic components based on crop components and graphene is reported. More specifically, by combining zein, a corn‐derived protein, and aleuritic acid, a major monomer of tomato cuticles and sheellac, along with graphene, biocomposite conductors having low electrical resistance (≈10 Ω sq−1) with exceptional mechanical and fatigue resilience are fabricated. Further, a number of high‐performance electronic applications, such as THz electromagnetic shielding, flexible GHz antenna construction, and flexible solar cell electrode, are demonstrated. Excellent performance results are measured from each application comparable to conventional nondegrading counterparts, thus paving the way for the concept of “plant‐e‐tronics” towards sustainability.

PEDOT:PSS in Water and Toluene for Organic Devices—Technical Approach

Poly(3,4-ethylenedioxythiophene:poly(styrenesulfonate) (PEDOT:PSS) water and toluene solutions were investigated in detail, taking into consideration their stability, wettability, transparency, and electrochemical properties, along with change polarity caused by dopant. As dopant, methanol, ethanol, and isopropanol were used with different dipole moments (1.70, 1.69, and 1.66 D) and dielectric constants (33.0, 24.5, and 18.0). Three techniques, i.e., spin coating, doctor blade coating, and spray coating, were employed to created PEDOT:PSS layers on glass, glass/indium tin oxide (ITO), and glass/fluorine-doped tin oxide (FTO) substrates with optimized technical parameters for each used equipment. All used PEDOT:PSS water and toluene solutions demonstrated good wetting properties with angles below 30° for all used surfaces. Values of the energy bandgap (Eg) of PEDOT:PSS investigated by cyclic voltammetry (CV) in solution showed increase energy Eg along with addition of alcohol to the mixture, and they were found in the range of 1.20 eV to 2.85 eV. The opposite tendency was found for the Eg value of the PEDOT:PSS layer created from water solution. The storage effect on PEDOT:PSS layers detected by CV affected only the lowest unoccupied molecular orbital (LUMO) level, thereby causing changes in the energy bandgap. Finally, simple devices were constructed and investigated by infrared (IR) thermographic camera to investigate the surface defects on the created PEDOT:PSS layers. Our study showed that a more stable PEDOT:PSS layer without pin-holes and defects can be obtained from water and toluene solutions with isopropanol via the spin coating technique with an optimal speed of 3000 rpm and time of 90 s.

High-dielectric constant (high-K) polymer nanocomposites based on nematic liquid crystals and CaCu 3 Ti 4 O 12 (CCTO) nanoparticles have been prepared. The host matrix is polymer dispersed liquid crystals (PDLC) in which LC (E7) droplets are dispersed in different polymer blends ratios of poly vinyl chloride/poly aniline (PVC/PANI). The PDLC (PVC/PANI/E7) in the appropriated ratios; (90/10/5), (75/25/5), and (50/50/5) were composited with 10 wt % CCTO nanoparticles. The IR spectra recorded for the PDLC nanocomposites present a spectrum similar to that of pure PDLC but with a slight shift of the peak positions. The addition of PANI and CCTO to PDLC enhances the thermal stability of the nanocomposites. SEM demonstrates agglomerates of CCTO dispersed in the polymer textures. Moreover, the addition of E7 facilitates the integration of PANI in PDLC matrix. The broadband dielectric spectrum shows high-frequency relaxation in addition to low-frequency interfacial polarization (Maxwell-Wagner type polarization). Besides, ε 0 at 50 Hz is in the order of 10 5 for PDLC/CCTO (50/50/5/10) nanocomposite. In addition, the computed energy density is found to be 74.66 J/cm 3. This presumed ratio could be accentuated as a potential candidate for energy storage application with respect to the considerations of device fabrications.
