“…The neat PCL film resulted in a tensile toughness value of 146.8 MJ m −3 agreeing well with the previously reported values (Table S7). 53 Spurred by the robust characteristics of (p-TEA)(p-TEAH)• PF 6 -PCL films, we set out to test the PENG output performance of their devices. The devices for these studies were obtained by placing adhesive copper tapes as top and bottom electrodes and subsequent encapsulation with Kapton tape for electrical insulation.…”

Ionic cocrystals with hydrogen bonding can form exciting materials with enhanced optical and electronic properties. We present a highly moisture-stable ammonium salt cocrystal) crystallizing in the polar monoclinic C2 space group. The asymmetry in (p-TEA)(p-TEAH)•PF 6 was induced by its chiral substituents, while the polar order and structural stability were achieved by using the octahedral PF 6 − anion and the consequent formation of salt cocrystal. The ferroelectric properties of (p-TEA)(p-TEAH)•PF 6 were confirmed through P−E loop measurements. Piezoresponse force microscopy (PFM) enabled the visualization of its domain structure with characteristic "butterfly" and hysteresis loops associated with ferroand piezoelectric properties. Notably, (p-TEA)(p-TEAH)•PF 6 exhibits a large electrostrictive coefficient (Q 33 ) value of 2.02 m 4 C −2 , higher than those found for ceramic-based materials and comparable to that of polyvinylidene difluoride. Furthermore, the composite films of (p-TEA)(p-TEAH)•PF 6 with polycaprolactone (PCL) polymer and its gyroid-shaped 3D-printed composite scaled-up device, 3DP-Gy, were prepared and evaluated for piezoelectric energy-harvesting functionality. A high output voltage of 22.8 V and a power density of 118.5 μW cm −3 have been recorded for the 3DP-Gy device. Remarkably, no loss in voltage outputs was observed for the (p-TEA)(p-TEAH)•PF 6 devices even after exposure to 99% relative humidity, showcasing their utility under extremely humid conditions.

Recent advancements in the utilization of naturally derived nanocellulose and nanochitin/chitosan have opened new avenues for self‐cleaning and purification applications to address environmental challenges. This review highlights the unique structural properties of bio‐based nanofibers, which are typically rich in hydroxyl groups that enhance their functionality in various industrial sectors. Through appropriate chemical modification, they can perform specific functions facilitated by carboxylic acids or amine groups. We explored the mechanisms by which these materials facilitate oil/water separation, ultrafiltration, and self‐cleaning processes, including the incorporation of inorganic nanoparticles, such as TiO2, to improve hydrophilicity and oleophobicity. Furthermore, this review discusses innovative fabrication techniques, such as spray‐assisted layer‐by‐layer assembly, which enhance the performance of nanofiber‐based coatings. We examined the potential of these materials for diverse applications, including food packaging, wastewater treatment, and personal protective equipment, emphasizing their role in promoting sustainable industrial practices. As the global emphasis on eco‐friendly solutions intensifies, continued research and development of nanocellulose and nanochitin is expected to drive significant advancements in materials science, paving the way for greener technologies.
