Multifunctional textiles combining ultraviolet protection, thermal insulation and superhydrophobic and aromatic performance were successfully prepared using an aluminum-doped zinc oxide (AZO)-embedded lemon microcapsule and SiO₂ dual-layer coating. AZO-loaded lemon microcapsules with average diameter of 1.5 µm were obtained via interfacial polymerization. Results showed that the high concentration of the AZO-embedded lemon microcapsule contributed to enhancing the waterproof property, aromatic performance, and visible and near-infrared light transmittance. The lemon content was up to 2.789 mg/g (weight of essence:weight of fabric). The water contact angle was high at 153.35°, exhibiting an outstanding superhydrophobic performance. The light transmittance decreased as the amount of AZO-embedded lemon microcapsule increased. The ultraviolet protection factor value reached 88.78 when the dosage of the AZO-embedded lemon microcapsule was 6%. Given the above research results, the cotton fabric coated with the AZO-embedded lemon microcapsule and SiO₂ dual-layer composite coating would have potential applications in the water/oil purification field and functional protective fabrics.

Textile textures formed through woven, knitted or nonwoven weaving technology have critical effects on the electrical and electrochemical properties of flexible electrodes. Therefore, the effects of textile structures, including porosity and pore configuration, on the loading amount of reduction graphene (RGO), the electrical and electrochemical properties were systematically studied. The results show that knitted fabric had the highest mass loading of RGO sheets and lowest sheet resistance among these three fabrics. However, the specific capacitance of woven fabric was optimum 40.5 F g⁻¹ at a scan rate of 5 mV s⁻¹ within the voltage window of 0–0.8 V, which was ascribed to its suitable porosity and pore size firmly anchoring the RGO sheets. Also, the RGO/woven cotton electrodes exhibited good cycling stability and excellent electrochemical stability without an obvious loss in the capacitive performance. The above results provide a theoretical basis for the selection of textile substrates for high-performance flexible electrodes.
