Microcapsules were prepared using a complex coacervation method by varying levels of concentrations of essential oils, such as eucalyptus, lavender, aloe vera, and citronellal. Chitosan and gum Arabic were used to form the capsule cover. Then, the microcapsules were applied to three woven fabrics: cotton, bamboo, and linen.

The antibacterial activity of all microcapsule-treated fabrics against <i>Staphylococcus aureus</i> and <i>Escherichia coli</i> resulted in inhibition zones of approximately 13 mm. The mosquito repellence of all fabrics remained high (90–100%) even after five washes. Compared to the raw fabric, the samples C8, L8, B8, and B7 effectively retain their desirable properties, air permeability, bending length, and crease recovery, showing no significant impact from the applied microcapsule.

Additionally, the impact of linear density on fiber performance was analyzed, revealing its crucial role in optimizing fiber characteristics. Increasing fiber linear density helped reduce the rate of regeneration of the core of the fiber at constant spin bath conditions and stretch, resulting into poor orientation of chains along the fiber axis as observed through fiber orientation analysis. Such poor orientation of chains enables an increase in fiber elongation by ~50% as linear density increases by a factor of two.

To replicate the processing requirements of large-scale CFRP manufacturing, a minimum pot life of 5 h was set as the target processing window, based on the time required to reach a viscosity of 3000 mPa·s. CFRP specimens fabricated with epoxy systems stored for 5 h after mixing exhibited impregnation behavior comparable to that of specimens prepared under the initial condition, while micro-CT analysis confirmed that void formation was effectively suppressed. Consequently, the mechanical properties of the CFRP specimens were nearly retained even after 5 h of resin storage.

Despite remarkable efforts to improve charge transport and carrier mobility in organic field-effect transistors (OFETs), the performance of OFETs still lags far behind that of halide perovskite semiconductor counterparts. In this study, we investigated ammonium-based additives, including halide-based ammonium salts and organic cations, to enhance the performance of OFETs. Among the investigated additives, tetrabutylammonium chloride (TBACl) resulted in enhanced charge transport and device performance when incorporated into poly(3-hexylthiophene) OFETs. Specifically, the TBACl-based OFETs exhibited an optimized average field-effect mobility of 0.24 cm<sup>2</sup> V<sup>−1</sup> s<sup>−1</sup> (best value ≈ 0.48 cm<sup>2</sup> V<sup>−1</sup> s<sup>−1</sup>), which was about 14% higher than that of the pristine counterpart (best value ≈ 0.34 cm<sup>2</sup> V<sup>−1</sup> s<sup>−1</sup>). These charge transport enhancements are due to improved film crystallinity, enhanced surface morphology, reduced interface traps, and chemical interactions between the chlorine ion in the TBACl additive and adjacent sulfur atoms in the thiophene units due to favorable electronegativity of the chlorine atom.
