“…Chitosan has a noncentrosymmetric crystal structure; therefore, solution‐casted chitosan films have a piezoelectric response of 6 pC N −1 . [ 180 ] Its piezoelectric response could be enhanced by neutralization to reach a value as high as 16 pC N −1 . [ 181 ] However, chitosan is flexible, but not stretchable.…”

Piezoelectrics play a significant role in modern electronics and electric devices. Thermal or mechanical stress on such materials induces a change in polarization generating an electric response, which is the sole effect of why they are so interesting. However, most piezoelectrics are rigid and brittle ceramics and thus difficult to integrate into wearable electronics that comply with human skin or organs. To facilitate their incorporation into stretchable, so‐called next generation electronic devices, researchers have focused on developing piezoelectric materials with improved properties. Significant advances are achieved regarding flexibility. However, marrying piezoelectricity and elasticity proved challenging, as elastomers, with their amorphous flexible network structure, cannot keep polarization permanently. Here the most recent developments in the field of piezoelectric elastomers are reviewed, and potential future applications in sensors and energy harvesting are discussed.

“…Cellulose is composed of a linear organic chain; it is the most abundant polymer on the planet and can be obtained from different sources, such as plants, algae and via microbiological fermentation [ 1 ]. Bacterial cellulose (BC) is produced from bacteria and microbial consortia in the form of biofilms or pellets, depending on the production conditions under which the microorganisms are subjected.…”

Bacterial cellulose (BC) is a biopolymer that has been widely investigated due to its useful characteristics, such as nanometric structure, simple production and biocompatibility, enabling the creation of novel materials made from additive BC in situ and/or ex situ. The literature also describes the magnetization of BC biopolymers by the addition of particles such as magnetite and ferrites. The processing of BC with these materials can be performed in different ways to adapt to the availability of materials and the objectives of a given application. There is considerable interest in the electronics field for novel materials and devices as well as non-polluting, sustainable solutions. This sector influences the development of others, including the production and optimization of new equipment, medical devices, sensors, transformers and motors. Thus, magnetic BC has considerable potential in applied research, such as the production of materials for biotechnological electronic devices. Magnetic BC also enables a reduction in the use of polluting materials commonly found in electronic devices. This review article highlights the production of this biomaterial and its applications in the field of electronics.

“…Particulate matter (PM) with an aerodynamic diameter of less than 2.5 μm (PM 2.5 ) seriously affects the health of individuals by penetrating into the human lungs and bronchial tubes . Therefore, the development of high-performance air filter (i.e., high filtration efficiency and low pressure drop) has become a hot research topic because it can balance protection and comfort. − In recent years, nanofibrous membranes have become the first choice for high-performance air filtration because of their large specific surface area, high porosity, and fine fiber diameter. − Electrospinning is a simple and versatile method to produce nanofibrous membrane. − Until now, many materials have been used for electrospinning, such as polyamide (PA), polyacrylonitrile (PAN), polyimide (PI), polyvinylidene fluoride (PVDF). − However, the common problems with these petroleum-derived synthetic polymers are that they are nonrenewable and nonbiodegradable, causing an energy crisis and environmental pollution. Fortunately, electrospinning preparation strategies based on biobased materials and green solvents have been developed.…”

Biobased high-performance air filters via green electrospinning are the key to reducing the energy crisis and the environmental burden. However, the complicated postprocessing limits its application. In this research, a green solution system with delayed volatilization was constructed, and a zein/cinnamaldehyde (CMA) composite nanofibrous membrane with optimized structure was produced by one-step electrospinning. The addition of CMA significantly decreased the volatility of the solution, deferring the clogging time of the nozzle and thus smoothing the electrospinning process. The time from the start of electrospinning to nozzle blockage increased by over 300%, resulting in a significant improvement in fiber morphology. The air filtration efficiency for PM0.3, the pressure drop, and the quality factor were 99.25%, 58.2 Pa, and 0.084 Pa–1, respectively, compared to the membrane without CMA addition and N95 mask. Moreover, the CMA improved the hydrophobicity of the zein nanofiber, which helped improve the stability of air filtration and endowed the nanofibers with certain antibacterial properties. This work is the first to report that CMA improves continuity in electrospinning, which will promote the development of green electrospinning and the preparation of a high-performance biobased air filter.
